Year: 2026

Whilst I await the arrival of suitably long bolts to continue the work on the centerplate case, I decided to hang the rudder since this would require some adjustments to the rubbing strake just added to the top of the transom due to its increased size.

First up was the rounding of the ends to something a little less right-angular.

Looks a lot better this way and will also hold the varnish for longer. Varnish and paint do not seem to like right angle corners.

Then I worked on the strake and the gudgen backing pad. This is not finished yet, but I needed to hang the rudder in order to find out how much of the strake to remove. The gudgeon fitting itself is bolted through the transom with bronze bolts for addition strength.

And the rudder in place.

It moves freely over its entire travel…

…in both directions. You will notice that there is quite a large gap between the top surface of the gudgeon and the bottom surface of the pintle. At some point a piece of copper, I think, has been wrapped around the upper part of the pin and it no longer goes down into the hole in the gudgeon, presumably to stop the two from rattling after being worn away after years of use. I am loath to remove the extra copper bit, so instead I will get some copper washers to fill in the gap between the two faces such that the rudder is resting on both of its fitting instead of the bottom one only which is what is happening now.

It is the pintle fitting at the bottom that is limiting the travel, not the gudgeon fitting just added. Good news.

So, another task can be crossed off the list. Hanging the rudder, that is, the rubbing strake is not finished yet.

Time for a cup of tea.

I took a short break mid-afternoon and made the next modification to the rubbing strake.

This replaces the screwed in eye that I believe contributed to the rot in the transom. I’ve used a nylon guide and a piece of copper folded over the strake. The purpose of the original eye and now this guide is to pull the downhaul line aside from the rudder stock so that it does not foul the rudder stock itself. The uphaul will just need a piece of copper over the strake as it is already off to one side.

Once the strake is properly fitted and varnished, Stockholm Tar will be spread on the undersides of the copper chafe guards and the will be nailed to the strake with copper nails. But that is in the future.

Back to work.

After work I continued the tasks.

This is how the chafe protection for the uphaul looks, albeit with the copper nails.

Here is the downhaul but not lead through the eye.

When the rudder is turned to port, then the line gets pinched and possible jammed by the rudder stock.

With the line fed through the eye, there is no real possibility of this happening.

The uphaul, however, leads differently, as you can see.

And even with the rudder hard over, the line is not pinched.

The bad news is that I found more rot, this time in the rudder blade. A group of barnacles, or is it a colony, on the inside of the rudder stock have worn away the layers of paint and exposed the plywood of the blade and over time, rot has set in.

I used a small chisel to dig out the soft wood as far as I could, really this is a project for next season and to be done properly, the rotten section needs to be removed and replace. But not this time.

The soft wood went deep into the wood by the line, deeper than I wanted to poke.

So, I mixed up 20ml of the penetrating epoxy and liberally flooded the area with the mix.

And by flooded, I do mean flooded. The hollow here was filled with the stuff.

This part of Shoal Waters has been waiting for the next batch of penetrating epoxy to be mixed and this got a liberal flooding as well. Again, this is a repair for another maintenance season, but for now, the penetrating epoxy will do the trick.

Time for a cup of tea.

The new, longer bolts arrive late afternoon, so I took the time to get those installed.

These three are in the forward end of the sides.

And these are in the aft end. However, I’m not happy with the diameter of the washers, so I’ve ordered some bigger ones. These will help to spread the load a little better.

I’ve used standard nuts for the dry fit as the nuts that will be put on for assembly are self-locking and I don’t want to be taking those off and on again more than once. For this purpose, the standard nuts are fine. The bolts will be cut down to the correct length once I am ready to install everything.

That’s it for today,

Time for a cup of tea.

The first task of the day was to check that the new template I cut yesterday actually fitted the camber of the aft deck.

The template was nailed back onto the transom and checked. Thankfully, this time the fit was good. The next task for the template was to cut the same curve but on the bottom edge and concave. This will be used to cut the underside of the messed up strake.

Whilst I was working on this I was pondering the forthcoming centerplate case sides installation and the final preparations. The bit that concerned me was screwing the new sides into the old wood of the fore and aft blocks. Although the sides will be stuck to the blocks with SikaFlex 291i, having the screws as well means that there will not be a need to clamp this in position. But I’m not sure that screws in the old wood will afford sufficient holding power.

So i decided that I will use stainless steel bolts instead with large washers. The downside of this will be the bolts sticking out of the case sides with the possibility of scraping hands. I’ll have to make sure that the bolts are as short as possible and with no sharp ends. The upside is, of course, that no holding power in the old wood is required.

During my lunch break my task on the rubbing strake fix continued.

The template was nailed to the strake and used with a table router to cut the correct shape into the strake. It turned out fairly well.

This cannot be said of my first attempt to cut the concave curve on the template.

As you can see, it is less than ideal. However, I used the newly cut curve on the strake to draw the line on the template and I’ll use a jigsaw to cut near the line and an oscillating sander to sand down to the line and then use that to cut the curve on the other side of the strake.

I noted that the temperature so far today has reached 15º C, so I will aim to get the centerplate case sides fitted tomorrow starting first thing and by that I mean as soon as it is light and before breakfast. The aim will be to get the first side, probably the port, installed with the other side in place but not glued. This is necessary as the pivot bolt needs to be in place with the spacer, drawing the two sides together.

Once the SikaFlex has cured sufficiently I’ll repeat the process with the starboard case side.

So, as soon as work is done for the day I shall carry out the final preparation work for the case sides fitting and if there is any time left, bearing in mind the things I have to do this evening, then I’ll continue with the rubbing strake.

Time for a cup of tea.

I was unable to carry out all the preparation tasks for the case sides due to the epoxy not really being cured enough, so I moved on.

Careful use of the jigsaw saw the concave side of the template cut pretty close to the line.

The sander made short work of smoothing the curve right up to the line. It is nice having the correct tools for the job.

The template was nailed t o the strake and the excess removed with the router. Quite a lot of shavings, good for using as tinder !

Here both sides are done.

I rounded the aft facing corners and then screwed the strake to the boat with two 2″ No.10 bronze screws. I may put another screw in the centre of the strake but otherwise, it will be stuck to the transom and deck with an exterior grade non-adhesive sealant as I’ll want to get it off next off season to make the other transom repairs.

It is a bit thicker that the previous strake and I need to round the ends off a little.

Otherwise, I think it is looking pretty good.

That’s all on the boat for today, I’ve other tasks to do in the house this evening.

Time for a cup of tea.

No varnishing today so I did nothing until my first tea break.

The first task was to remove all the cramps from the glue ups and see how they look. Not too bad and during my next break I’ll run them through the planer.

The case top looks good. It is a little thinner that the original pieces, but since most of it is under the bridge deck, I doubt that this will matter much.

The rubbing strake look fairly good too.

There’s a little section that I left unplanned since the strake will be shaped and the slightly lower part will mostly be removed.

However, when I tied it to the transom I noticed that there is a problem. The starboard end is lined up. with the top of the aft deck.

As is the port end.

But the middle is about 10mm lower than the deck. I screwed up somewhere ! The strake is not curved enough to fit the camber of the deck.

There are two ways to fix this. The first, and easiest, would be to add another laminate or two on top and then shape the top wth a plane to get the curve correct. The downside of this is that the underside of the strake will be a different curvature unless it is also reshaped.

The second method is to shape the top surface until it fits and then the bottom. The downside is that this will reduce the 40mm high batten to 30mm. And that means having to be very careful with the mounting screws.

I’ll sleep on this one but right now, I’m tending towards the just reshape and make it thinner option.

Still, whichever option I choose, I need to make an accurate template.

And that means removing the chain plates that are screwed to the transom. I don’t know what these are for, one suggestion is that they were for running back stays. Still, they need to come off.

Of the six screws holding these fittings in place, three were stainless and the other three were the remains of old brass screws and had to be drilled out.

With the fittings removed I nailed a piece of plywood to the transom such that it protruded above the deck level at the highest and was about 100mm wide. Then I used a carpenter’s pencil laid flat on the deck and slid along the deck the point touching the plywood. I checked it several times and then took it into the workshop, cut the wood stating clear of the line and then used the belt sander to sand down to the line.

The new template shows just how much error there is in the new strake.

Both ends are way off.

Still, with a fairly accurate template I can hot glue this to the strake and then use a follower bit in the table router to remove the excess. But that’s for another day as I have some non-boat projects that need to be done and I must make a start on those.

Time for a cup of tea.

Today was going to be a little bitty since the epoxy and glue work that needed doing meant that other tasks had to wait until the epoxy set cured and the glue dried properly. The varnish work was completed before breakfast. Later I made a start on glueing things.

The first item on the list is the block extender. I placed the new piece on top of the block and drew the outline of the block on the underside with a soft pencil, then sanded the sides of the block away until it was down to the pencilled line. This piece was glued on with a temporary screw since clamping is not possible just here. As with all the other temporary screws, the holes will be filled later.

Next up were the case sides. The adjustments that were made during the dry fit meant that unsealed plywood edges were exposed and these all had to be coated with neat epoxy.

This means that not further work on the case can be carried out until the new piece of wood on the aft block is firmly stuck and then shaped and the epoxy on the cases has cured.

The new plywood on the transom needed another coat of stain as they were still obviously lighter that the rest of the transom.

Something I did forget when I had the stain out yesterday was the gudgeon backing pad.

So that was next. This is the second coat and I think that one more will be enough to match the transom.

Time for a cup of tea.

Once the glue had set enough to withstand some strong sanding, I took a sanding disk on an angle grinder and the belt sander to shape the aft block.

It’ not perfect just yet, for that I need the case sides in place.

Now comes the task of laminating a new rubbing strake on the transom. The original was 30mm wide and as you can see, the centre line for the screws goes straight through the transom/deck joint. This is not good. You can see in the photo above that the joint has cracked and I’ve no doubt that this was due to the screw acting like a small wedge as it was screwed in. The crack may not have occurred immediately, but the pressure trying to open the joint was there until the point that the glue failed.

So, I cut the laminates such that the strake is 40mm wide and this will move the screw holes down into the top of the transom.

The next task after cutting the laminates was to make the jig. I used the cardboard template that I made previously to draw the curve on a suitable piece of gash wood, in this case MDF, then screwed blocks to the board against which the laminates will be clamped.

Like this. The jig was covered in film to prevent the laminates from being glued to the jig and the laminates covered in glue on both sides except for the outermost ones which only had glue on one face. These were stacked and put into the jig and clamped in place.

Laminating can take a fair number of cramps.

And you can never have too many cramps in the boat building business.

One more glue up was required and that is the above which will form the missing top of the centerplate case as I did not have a single piece the correct size.

So far, a good day.

Time for a cup of tea.

Annoyingly, as I was drinking my tea I realised that I had forgotten to coat one of the centerplate case sides on one end. So I mixed up another shot of epoxy and rectified that omission.

This was the missed section and once I had coated that I still had a lot of epoxy left. I went around trying to find things where I could use up the remainder of the shot rather than waste it. I didn’t have a lot of time for this as I used the fast hardener and I could feel the heat of the reaction as I held the plastic cup in which I mixed the epoxy. I had perhaps five minutes before it became unusable.

Some went in this screw hole.

And I used some more coating the top of the transom where the rubbing strake had been and also the edge of the plywood that makes up the aft deck.

Since I was in a hurry I didn’t clean these areas up first, just slapped on the rapidly curing epoxy. If it subsequently falls off when I’m fitting the new rubbing strake, then I’ll just clean up the area and put more fresh on.

I think that is all the construction, epoxy and glueing work done for today and I think I have covered everything that was on the critical path, so I can get one with other tasks now the were previously blocked.

Back to my cup of tea.

Have had a break I started on the Shoal Waters name plate.

The old fixing holes were plugged and once the glue had dried sufficiently, the plugs were sanded flush. The board was then mounted on the CNC Router table and given a surface cut just deep enough to cover the entire surface.

Then a 6mm bit was used to cut out the larger areas of waste.

Followed by 1/8″ bit.

Finally a 1/16″ bit was used to finish the letters. I messed up the positioning of the two right hand side mounting holes, I’ll have to fix that later. The board was given a light sanding to remove any fuzzies and taken inside to warm up.

After about an hour the board was warm so I applied a coat of clear epoxy.

The letters are 3mm deep and will be filled with epoxy coloured with white pigment. However, if you skip this coating stage you run the risk of the coloured epoxy bleeding in to the surrounding wood, especially if it is porous. The clear coating serves as a barrier to prevent the bleeding.

The epoxy used will not be cured for 24 hours, so the next stage of this task will not be carried out until tomorrow evening at the earliest.

Time for a cup of tea.

I made an early start thing morning, but only for the varnishing which I carried out before breakfast. After that I started making some muffins. English ones not the American kind.

Spoiler alert, this is how they came out a couple of hours later.

There were eight, but we had to try them out. This is the first time I’ve made muffins like this and they worked out well.

Whilst the transom was still warming up, it might have been reading 13º C at the weather station but the mass of the boat takes a little time to warm up, I put masking tape on the graving pieces…

…and on the transom. Epoxy will squeeze out of the seams when the graving pieces are put in and the tape helps to prevent that from getting on the rest of the transom.

I used an infrared temperature meter to check the temperature of the transom and once it had reached 13º C I applied neat epoxy to all the edges of the graving pieces and the recesses, then applied some thickened epoxy to the mating surfaces. This was to fill any gaps between the mating surfaces and was just a thin layer, not loads. I used the fast hardener since I want this to kick off quickly and to be cured before the temperature drops below 10ºC. You can see where I have scraped off the squeeze out.

You may also notice that I’ve used some modified truss head screws to hold the graving pieces in place since there is no practical way to clamp them. I’ll fill in the screw holes once the epoxy has reached full strength.

It is imperative to epoxy all the edges of the plywood to prevent the inner cores from soaking up water. Some of the remaining epoxy was liberally spread in the top of the new transom piece.

It is also fairly important to remove the tape before the epoxy hardens too much. When the seams stop oozing then it’s time to get the tape off. I will have to apply more stain to the graving pieces, I’ll do that later.

Once that was out of the way it was time to dry fit the case sides. they are a pretty good fit, just a couple of slight modifications to make them fit without needing a mallet.

The new top part of the aft block is too short and I will have to make a piece to fit on top of this to bring it up to the level of the case sides.

The pivot bolt almost fitted through but I did have to widen the hole in the starboard side slightly to allow the bolt to go in easily. It is out of focus, but you can see the pivot spacer in position. I wrapped a wire coat hanger around the spacer to be able to get it in the correct place and so that it doesn’t drop out when I take the bolt out. I needed to tighten this up to the point where the spacer is hard against the case sides as this draws the sides together a little.

I was delighted to see that the two original top pieces that came off the old case fit perfectly on the new on. I must be doing something right.

There is virtually no step between the new case and the tops.

The top piece that went in here was destroyed in the removal, unfortunately, but I have some Sapele left and can make up another one easily enough.

I stopped at this point as I made three mistakes one after the other. Getting tired and there isn’t really any hurry any more.

Time for a cup of tea.

So then, moving on…

I put another coat of stain on the graving pieces and then gave the entire transom another coat of the stain. As you can see, it has made a complete difference. The graving pieces are not so noticeable now and the entire transom is darker. I expect that this will lighten a little once it has dried, but it is looking pretty good.

These are the cutoffs from when I made the new aft block top and I can use one one them to make the piece I need to heighten the block.

Like this. The new piece will be glued onto the top of the block and shaped to fit. Once the case sides have been properly fitted I’ll cut it down to the correct height since it is deliberately too high.

Finally, for work on Shoal Waters today, I removed the end pieces of the rubbing strake at the top of the transom, making space for the new one once I have made it.

The deck and transom under the rubbing strake seems to be in good condition. This is the area where the repair was made…

…and this looks to be original.

Time for a cup of tea.

With the weather forecast for the next few days indicating that the temperature is going to be 10º C or above, I have a shed load of things to get done on Shoal Waters. Here’s the list in no particular order:

1. Sand the transom and the graving pieces.
2. Stain the transom & graving pieces.
3. Epoxy in the three graving pieces.
4. Dry fit the centerplate case sides & adjust where required.
5. Fit the case sides.
6. Cut back the aft deck to good wood.
7. Epoxy glue in plywood to repair the aft deck.
8. Fit the through deck fitting for the aft navigation light.
9. Laminate a new rubbing strake for the top of the transom.
10. Epoxy glue the backing pad on the transom that was cut away for access.
11. Carve ‘Shoal Waters’ into the old name plate.
12. Carve ‘Maldon’ on to a new name plate or the existing one. TBD

That is what I can think of right now and it is a fair bit of work to get done in the time I have.

So, after the morning varnish application, during a tea break, I made a cardboard template for the curve of the aft deck.

The idea is to laminate a new rubbing strake for the entire width of the transom. The pieces I did not cut off before will be removed and replaced by this new one. The reasoning is that I will need to remove the rubbing strake the next time Shoal Waters is out of the water for maintenance so that I can repair the repair that is giving soft returns. If I make an entire new timber, screw it on with 304 stainless screws, with a non-adhesive sealant between it and the transom and aft deck edge, then I will be able to remove it without damaging it when the time comes to make the repair. It will be alot easier to make the whole thing rather than pieces here and there.

Hence the template. I’ll also use this template to replace the timber on the transom that is under the aft deck on the inside. This was originally a single piece, I think, but has been cut away in sections over the years. Now that the aft lockers have been removed, there is no need for the timber to be in pieces, so I’ll do the same, laminate a new timber as part of the transom repair next time.

The next task was to clear up the work tables again. Lots of odd pieces of wood went either into the burn barrel of into the useful bits of wood box. I need to find somewhere to put all the pieces of wood that I have cut out or otherwise removed from the boat.

I also need to service the CNC Router as it hasn’t been used in two or three months and it needs to be cleaned up, oiled and the calibration checked before I do any work on the name places. I have several other non-boat projects that need the CNC Laser and the CNC Router and I hope to get these done before the temperature drops again.

The staining needs to be done and dry before the epoxy work and since it was 10º C I took my tea break and applied a coat of stain. To show you the difference I’m putting up a set of three photos showing before, after scraping and after staining

I think the stained version is quite good and, unlike the coloured varnish or paint that was applied before, it does not hide the problems. It may lighten a bit once it has dried and I’ll decide then whether to put on another coat.

The graving pieces also received a coat of stain.

The reason for staining all these before gluing in the repairs is that if you glue first and then stain, unless you are ultra careful not to get glue or epoxy on the wood you will find that the glue stops the stain from soaking into the wood fibres and you get blotchy bits. Doing it this way prevents that and the glue does not have any problems being applied after the stain.

So far, so good.

Time for a cup of tea.

This little fitting was the reason that there was rot or water damage in the transom.

Its purpose was to guide the up and down hauls form the rudder into the cockit.

You can see it this photo on the aft deck above and to the left of the gudgeon fitting.

In this photo with the transom opened up, you can see where it was screwed through the deck and into the top of the transom. There is some sealant left in the wood where the screw holes was cut in half.

The problem was that despite the sealant, the two rudder lines pulled in such a way that the fitting was twisted slightly one way and then the other each time the rudder was hauled up or down. Eventually, this broke the watertight seal and allowed water, probably mainly rainwater, to seep into the wood resulting the damage you can see.

I will not be putting this fitting back. If you look in the phot prior to the one above, you can just see a groove in the rubbing strake where the uphaul has worn into the wood over the years.

What I will do instead is to nail a piece of copper over the rubbing strake where the two hauling line pass. That should stop both problems.

This is another thing that needs a little bit of attention, the aft navigation light. It was screwed to the support with steel (rusted) screws and the cable won’t go through either the hole in the back of the light, nor the hole in the deck, due to the crimp connectors. So, I shall fix both of these issues so that I can put in the deck gland.

Tomorrow !

After looking at the nav light I spent some time checking the CNC Router, cleaning it, oiling the linear bearings and so on. Nothing appears to be wrong, nothing is binding. All good news.

Time for a cup of tea.

Varnishing first thing and I shall be very glad when all this brightwork is done !

The first task of the day, apart from the varnishing, that is, was to check that the epoxied templates, now a solid block, fitted into the transom. I am very pleased to report that it fitted without any modifications. I hadn’t trimmed the top edge as there was no point doing that if modifications were required.

The fit from the inside.

It was a simple job to trim back the tops to match the inner laminate and then give it a quick sand to smooth any rough bits.

With the graving block in place now, you can see that the tops all match the line of the underside of the deck.

This part will be out aside far a few days as the next stop on its journey is to be epoxied into place and for that, the temperature needs to rise a bit.

Next up is the gudgeon backing pad that had to be chiselled off. This is fairly straightforward, two piece of marine plywood the correct size, glued together, shaped and sanded. The only difficulty in this is that the original backing pad is half an inch thick and my two pieces of plywood measure 12 mm, nearly 1 mm thinner. Now that shouldn’t make a huge difference over the distance between the upper and lower fittings, but if it does, then I have some bronze washers that are 1 mm thick which I can put between the bronze gudgeon fitting and the backing pad.

It might be that the layers of varnish on the backing pad and the thin layer of sealant between the pad and the transom will compensate for that 1 mm difference. I shall only find out when it comes time to fit the pad and fitting.

For now, I cut the two pieces of marine plywood from some of the offcuts I have from the centerplate case sides, drilled three locating holes and glued them together. NOt epoxy this time as this pad is not structural. Why three holes and not four? With three you can’t get the pieces the wrong way round.

There are two remaining tasks to complete before the transom repair can be completed. Firstly, glue the large backing pad on the inside of the transom back together. It was cut away to allow the construction of the graving block. Secondly make the other two smaller graving pieces for the minor damage to the transom and route out the transom to accept the graving pieces.

After work I set about making the other graving pieces for the transom .

Firstly the larger of the two damaged area which was a little tricky due to the bronze fitting that impeded the router. I could have taken the fitting off, I suppose, but that was a rabbit hole down which I did not wish to fall.

Instead I used a chisel to finish off the recess.

A short while later, the graving pieces was completed and I moved on to the other area.

This time the recess was well clear of the bronze fitting, but I still had to modify the upper right corner.

And here is the graving piece for this recess.

That is all the graving pieces and recesses done for the transom. The next time Shoal Waters is out of the water for the off season, the repair that you can see in the photo will need to be removed and redone as it is virtually all giving soft returns when tapped. I’ll probably start in the middle of the upper piece and cut it away and then explore the damage from there, but I suspect that it all has to be removed.

A job for another Winter season, methinks.

One thing I need to remember to do is to make a template for the rubbing strake at the top of the transom. Or rather the bit that is missing. I can get most of it from the top of the main transom graving block but I need to extend the curve on the template to meet the strake where I’ve had to cut it away. The reason for this is that I want to laminate a new piece to fit in the gap rather than get an oversize piece and curve it top and bottom.

Finally, for today, the shaped gudgeon backing pad.

Time for a cup of tea.

Just to give myself a change from the normal morning routine, I didn’t varnish the brightwork until this afternoon. Translation, I overslept and didn’t have any time before starting work !

Nevertheless, these items did get a coat of varnish but on the reverse side to the sides coats before. These all have four new coats of varnish on the first side and I’ll do four on this side as well.

I checked the new bolt length for fit on the centerplate case sides and there is plenty of length now.

The next task was to get the laminates for the transom repair made, starting with the outermost. As this is the face that will be seen, it needs to be as perfect as possible. Grain going in the same direction as the wood surrounding it and with as few gaps around the edges as possible. This is not difficult, it just requires a bit of to and fro as you dial the size in to fit exactly. I normally cut the piece about 1mm too large, offer it up the the gap and cut off fractions until it fits exactly.

What I did not do was the same thing for the top edge. I made the sides fit, as you can see, but left the rest too large. This will be fitted later when the inner laminate is done and the three pieces glued together.

Time for a cup of tea.

After work I set about making the other two laminates for the transom repair.

This is the inner laminate and like the outer one, the top edge was not finished.

And this is the inner laminate.

This one wasn’t quite such a good fit, but this will be filled with thickened epoxy when the plug is glued in place.

I traced the curve of the underside of the deck on the inner laminate. It is quite rough so I decided to smooth it out.

I clamped a flexible batten to the wood such that the edge ran along the pencilled line, more or less and then drew a dark pencil line along the batten.

Now the curve is fair and I can cut it out.

The result looks lopsided and that is because it is. The repair is not quite centred on the transom, so the curve is not symmetrical.

But, as you can see, it is a pretty good fit.

All that remained was to locate the laminates and I did this by drilling four 3.2 mm holes in the inner laminate, putting all the laminates in place and drilling through the holes right through the inner laminate and halfway through the outer such that the holes did not appear on the outside of the outer face.

Short piece of bamboo skewer were inserted into the holes to hold the laminates in position. This was dry fit to check that I hadn’t messed it up and then the laminates were brought inside to warm up.

Once the laminates had warmed up it was time to epoxy them together.

Neat epoxy was spread on all the surfaces to be glued and left for a few minutes to soak in a little before the laminates were assembled, using the bamboo skewer pieces to locate the three in the correct relative positions. Lead weight was used to apply clamping pressure and the excess squeeze out removed every quarter of an hour or so the avoid having to deal with hardened epoxy later on.

With the weather due to warm up into the low teens at the weekend, this plug will be ready to be glued into place when a suitable temperature is reached.

All in all, a satisfactory day’s work.

Time for a cup of tea.

After I had lunch I still had some time left on my lunch break, so I decided to cut out the top section of the transom that was damaged and giving soft returns when tapped.

I was surprised to find that the damage was quite extensive.You can see the area that was marked as needing a graving piece, I’ve had to cut entirely through the transom. You can also see that the rotten/damaged wood extends into the aft deck and down behind the backing pad upon which the rudder gudgeon was fixed. That meant that the pad had to come off and in the process of removing the rudder fitting I found that only the lower two screws were holding. The upper two came out without needing to unscrew them.

So, that part of the transom has to be replaced and the reason for that is that if nothing was done and the top part of the rudder broke away from the transom due to the rot behind it, you would be unable to control the boat and that is a safety issue.

I went back to work at this point and continued at my next break.

From this point I have to chase the rot along the deck and the transom to find good wood before I can rebuild the transom.

This is how much needed to be removed of the transom before I found good wood. The deck was also cut back a little but not that far. The rot seems to have travelled downwards.

I have no idea what this feature is, it was filled in with epoxy but you can see that it was painted at some point and may have been an old repair made by cutting out the ‘scoop’ of wood and then sealing and painting it.

On the other side I had to take the beading at the top of the transom back a little further than the plywood./

This is the centre section and I think that the pad of wood glued to the transom from the inside is either a backing pad to spread the strain of the rudder or a repair. Possibly even both.

Still, this now needs to be dealt with.

The repair is not difficult despite looking quite extreme. I’ll cut a plywood router guide and nail that to the transom about 5mm out from the hole and then use a router follower bit to make the edges of the hole square to the face of the transom and square to the sides and bottom of the hole. Then I shall make another plywood template that cuts a hole about 10 mm wider and taller than the hole and remove two thirds of the thickness of the edges of the hole. I’ll repeat this once more such that the edges of the hole are stepped instead of straight. The hole will then be filled with three layers of plywood with each piece filling one of the steps.

I’ll need to remove the big pad on the inside and the batten that runs at the top of the transom since the glueing is done from the outside inwards and those will get in the way. A portion of the aft deck will be removed so that I can graft in a new section once the transom is done.

If all goes well, this should only take a few days to repair.

Time for a cup of tea.

The first thing to do is to cut away the sections of the transom that will impede the router. I decided not to remove the centre backing pad as I do not know how it is fastened on at the back and this way is quicker.

The second thing to do is to make a template for the curvature of the top of the transom since all the filler pieces will need to follow this curve or the deck will not sit flush with the top of the transom when it is repaired.

The transom is three quarters of an inch thick or a fraction over 19 mm. The marine plywood I have is 6 mm so three layers of that plus epoxy will be around that thickness. All well and good.

Time for a cup of tea.

After knocking off from work I set about cutting the stepped opening.

Firstly the curved template. This was fairly easy to do, I just pressed a piece of cardboard on the outside and drew under the aft deck on the inside and cut along the line. Easy.

This is the routing template. It is quite large since the cut out gets bigger each time it is used. This will straighten the edge of the current raggedy hole.

And this is how it is used. The template is nailed to the transom with panel pins and a bottom follower bit in a trim router is used to cut away the excess wood all the way through the transom.

Here is the result of the first pass, nice straight edges.

The only drawback of this method is the rounded corners. The top ones can be cut away with a sharp chisel easily enough, but the bottom ones are a sufficient trial that I round the corners of the inserts instead.

This is the result after three passes, each one larger than the last but a shallower cut.

This is a slightly better view. I checked with a piece of plywood and the two outer cuts are about as perfect as I’m going to get. The inner cut is 1mm deeper than the plywood as three layers of 6mm is 18mm and the original transom is 19 mm so there always was going to be a discrepancy, but I can live with that.

That’s it for today, it’s dark and cold.

Time for a cup of tea.
