I think another update is in order. Box, many thanks but actually the frames on the photo were roughly cut , they were later finished to the exact pattern. Keith, it was actually very easy to glue the mirror pattern on the back. I am pretty sure there are already significant tolerances in the build, a bit more to the left or to the right will make no difference I think! I just managed to scrape a few moments here and there to work on the boat. I first finished all the frames to the exact pattern using the disc sander and mostly diamond files, which remove a lot of wood quickly. This took a while as the plywood at 6 mm is pretty thick. Then, I printed mirror patterns for all frames and with scissors cut the outline. Then I simply glued the frames to the back of the pattern. It actually worked pretty well. I could not resist aligning the frames, nice curves I must say... The straight parts that ruin the poetry will later be cut off, they are there just to help to set up the frames. However, this was the easier part. I now need to cut the bevels, both for the outer and the inner planking. This is pretty challenging. The diamond files are not useful here. The disc sander is far too aggressive and far too large. What actually made the task easier was to attach round sand paper to the Dremel. I like this trick, it sands not too aggressively but also is flexible and can fit in tight spaces. A mountain of work left, I ve only sanded the bevels for two frames. I also printed the patterns for the keel and stem. I think I will cut the deadwood en block instead of building it up. I am not 100% certain how the boat will be assembled, probably the right side up as the frames will be permanent so need to somehow be well attached to the keel. We ll see. Regards Vaddoc

Do not worry. The smoother the better. You will not regret the work you put in preparing the surface for paint. The primer magnifies faults 10 times, the paint a hundred. 0000 wool is something like 400-600 grit I would think. No issues, both acrylics and enamels will love your smooth primed surface.

A bit over 2 ft Bob, around 70 cm. The longest plank should be 80 cm in length.

Now, I need to correct a couple of mistakes. The actual frame count is 16 as No 17 would be the transom. Furthermore, there only 14 frames in the above arrangement as somehow I missed two! In any case, the templates have been glued to the 6 mm plywood sheet. This is very thick plywood bought from Cornwall models, it is very good quality with no voids, it reminds me of marine plywood although the wood is soft birch. The little Dremel Motosaw is actually doing a pretty good job and is cutting the plywood with relative ease. The frames at 6 mm thick I think will be sturdy enough for the job. All frames will need to be finished to the exact lines. Then, somehow a mirror paper pattern will need to accurately be glued to the other side to allow for the inner bevel to be cut. There is a lot of cutting and finishing to be done though!

Dear all, many thanks for your comments and likes. Unfortunately It took me a while to come back to my log as life has gone into hyperdrive again. All the frames are now in place and strengthened with pieces of wood. The boat is ready to be planked! However, I will temporarily hold the build and concentrate bringing the Launch to the same point. I think it will be interesting, these two boats are completely different in shape and I am curious how the planking arrangement will compare. A few final photos, the log will continue with the (clinker) planking, provided I will manage to get the 2 mm beech planks to bend.

Brian, you wheel came out fantastic! Very impressive and precise work. Your log is a joy to follow

You know how it goes Bob. Good times follow bad times until things go bad again. We just need to enjoy the good breaks and soldier on during the bad ones. Soon you ll be back on your boat, scratching your head trying to figure out the rigging. Stay safe Vaddoc

Beech is cheap Bob, I think around £4-5 per sheet 1000 x 100 mm. Pear, cherry and the other premium woods are much more expensive. If you visit both sites you can check the prices. Yes, it is a wood I very much like. It bends nicely and I like how it combines with pear. Now, for the Deben I used maple which is a fantastic wood for planking. I did not appreciate however that beech, although it bends as nicely, is also much harder. I foresee troubles ahead!

Welcome aboard Bob and Patrick! I am really sorry it has taken me so long to post a reply-life has gone into hyperdrive. Still, I managed to do a bit of work on the boat!The Yawl is ready for planking, so time to bring the launch to the same level. First, I ordered some more wood, this time not from Oliver at Arcowood but from Massive Holz. Once again I find that the former provider indeed selects the timber that is sent out. The latter does not seem to do this as much. I received some sheets that have defects and colour variation which I think should not have been sent out, considering we pay £10 or so for a little plank. (I edited this part to be fair as most of the sheets were fine) Then, I finished the whole boat on CAD, based on plywood frames 4 mm thick. The reason being I have 2 large sheets of 4 mm plywood I had laminated myself for the Yawl. These frames will be completely hidden so no need to sweat making them from expensive pear or cherry. However, after I had finished, I cut half a frame and realised that my plywood was delaminating but also that 4 mm would not be thick enough to withstand the pressure during planking. I will use beech which might bend nicely but at 2 mm, is also a very strong wood. So, back to the drawing board. I ordered some plywood 6.5 mm thick from Cornwall models and changed the frames to 6.5 mm. This took a decent amount of work! So, here is where we are now There will be 17 frames, initially very long to form the building jig, then cut to length. This is how to fit 17 frames in a 600 x 300 mm sheet! It is great fun building this boat, it builds like a clipper with its rabet, horn timber, dead wood and all but it is such a tiny boat! It will even have a bit of deck... Next update hopefully will have a bit of saw dust. Take care Vaddoc

Deadeyes, like photo bellow

Take a small piece of plank material, rest it on the frame, slide it down on to the rabet line, cut the bevel so the plank thickness is all in the rabet groove, with the plank piece resting on wood in both surfaces. Do the same for all frames (the angle will constantly change). Connect all the rabet segments you ve cut eyeballing things and/or using pieced of plank material. Rabet done

It might be easier to paint the hull upside down or something may go horribly wrong and the whole thing needing to sand down and re-do. If you paint the hull, it will need sanding and sealing anyway so that means treating it rough. I would finish with the hull and then proceed. For the rest of the build, rest the hull on something that will not scratch it.

Vlad, I ve only just managed to catch up with your progress, you are doing a fantastic job, both your deck and your boats came out great. Some of your photos are truly amazing. You are clearly having too much fun!

Brian, this looks lovely, looking forward for the rest of the journey. Enjoy your vacation!

Replace the wood with something better?

Fantastic work Gary. That machine on the deck is amazing.

Now this is a proper job! Very nice. Looking how long, wide and flat this boat is and how shallow draft it has and with all this armor on top, I can't help thinking that it would twist very easily. The pumps would probably work round the clock to manage leaks.

Nice work Keith. Quick question, these smoothbore guns, were they still firing round balls?

3 jibs/staysails, one with a boom, 2 sets of backstays, top sail on a yard and a gaff sail with reef lines etc - simples. Hats off to you Spyglass! 😄

Very nice Dick. I only just realised it has a flat bottom. This is a bit unexpected, the Mediterranean sea and especially the Aegean sea can be difficult, I did not know they were using this design back then.

Some more progress, time for another update. Things are getting now a bit complex, I ll try to explain as best I can I have been able to work on and off on the boat so far but this is now becoming increasingly difficult, for the next few months, I ll be working 6 (and a bit) days a week so I expect things to slow down to snail pace. First of all, I decided to lighten the frames significantly. After the planking is completed, I will need to install steam bend ribs in between the frames and simply there will not be enough space for my hand to fit in. So, I cut large pieces off but left two cross beams, one at the base and one mid-frame that will be easy to cut off later on with the dremel wheel. The frames are still very solid. Next was the big job of cutting the rabet and shaping the hog. Now, this was properly difficult. It is impossible to follow the lines in the printed templates due to the large tolerances of my work but I am not too far off either. One interesting thing though is that the boat seems to have corrected my draft error. In my plans I had made the rabet a curved line but now it seems to have flattened. I started cutting the rabet mid ships where the planks meet the keel almost vertically, still however it made a difference in the fit. First photo is fit without rabet, second with. Difficult to capture but it is better. I then took a break to clean and sand the transom as it will soon need to be fitted. Lovely solid piece of pear wood. Then I thought I wood install the sternpost knee. This is screwed and glued. In the photo above I have also added some wood next to the knee, cutting notches for the two aft frames. Let me explain why: It is very important for the garboard plank to be fully supported along its bottom edge. The rabet is not enough, this is why the hog is needed to add more supporting timber. However, I made two mistakes. One is that I did not make it long enough. It should extend from the sternpost to the stem so that after bevelling, it will support the plank for all its length. So, I am adding wood to the stern and will do the same for a short distance at the bow. Second mistake is that I did not make it thick enough. Putting the bevels, it gets very thin. So the pieces that I had screwed on top of the keel, thinking they will be just temporary and used to hold the frames in position will need to be permanent. These will also help with the ribs later on as their position on the keel will be already defined. I have replaced the pieces that will not be used for gluing the frames, the ones that will be sacrificed are marked with an X, these will be removed with the frames after planking and replaced with nice wood without screw holes. Then I cut the rabet. Forget about plans! It was done with just eyeballing the angles and using small pieces of wood. This is where more wood needs to be added to support the gardboard up to the stem edge. I tried a piece of 2 mm cardboard to see how the planking would go. It looks ok! Then with a big push I finished the rabet. A bit more material needs to be removed from the sternpost Now, another task was actually to reshape and sharpen my 4 mm chisel. So far I have been sharpening it free hand but now the bevel is so curved that it affects its function. Now, a few years ago I had made a simple honing guide with scrap wood, metal and bearings. I dug it out and used it. Perfect results! The next photos show the jig and how curved the chisel was. Since I ve honed it to a mirror finish There is also another thing that is troubling me, the wood I chose for the planking. I chose 2 mm beech. For the Deben I had used 2 mm maple which was perfect and very pleasant to work with, easy to cut, easy to shape and bend. However, the beech I received is much harder and resists bending plus it is 2,2 mm instead of 2. The planks will be cut with a knife so I expect a big struggle. I hope at least that the wood will respond well to steam bending (it should really being beech). As Brexit is getting much closer I put in another big timber order from Germany. I will have enough lovely wood to last me for years, pear, beech and cherry. I hope it will not rot or cup with the huge variations in temperature and humidity we have hear in Britain. Regards Vaddoc

Couldn't do this Druxey as it was all covered up by the filler pieces. Maybe it will sort it self out when dry

A bit more work done and time for another update. The boat is progressing very slowly. I cannot work as often as I would like and It takes me a while to remember where I left things, it is a pretty complex boat. Also building (kind of) the Chapelle's boat at the same time is not helping much...Still, some real progress made today. First of all, I printed out the patterns for the bow and stern to check how close to the CAD designs the wood pieces actually are. Happily, they are very close. I then finished the transom. I thought of leaving wood on for a safety margin, as I think is standard practice in actual boat building, however it is much easier to sand the transom now. I then glued and screwed the sternpost to the keel. I first drilled 0.7 mm holes to the keel, then taped the sternpost to the keel and hand drilled the rest of the way in the sternpost. Then I counterdrilled the holes in the keel to accept the head of the screw and screwed the 2 pieces together, with PVA in between. The joint is rock solid, the holes will be filled later on. The procedure was repeated for the stem but here I hit a snug: The keel will need to be notched for the rabet and might hit the screws if placed laterally. So I drilled new holes, this time at the midline. The stem looks like Swiss cheese but I ll fill the holes later on. Then, I made again the hog or apron as the previous piece had some dents. Now, I had to figure out a way to make sure the frames are correctly placed/spaced but also that the keel is secured to the frames but in a non-permanent way, so that the frames can be removed later and replaced with ribs. The way to do this will be to screw wood pieces to the apron and glue the frames to these pieces. Then unscrew these when it is time to remove the frames. So here it goes: The previous apron was cut up and wood inserts were made to go in between the rib spaces. The sides that will be epoxied to the frames were marked. Then these were lightly glued to the paper template of the apron Now, the keel has a slight bend laterally so i used some clamps to bring it in line with the apron..It straightened a lot Next the filler pieces were removed, the paper template removed from the apron which was then sanded clean. Then the pieces were screwed on again and the assemble glued and screwed on the keel This did not go as well as I would like because the apron, being very wide and only 2 mm thick, cupped from the liberal use of PVA. I do not think this will be a problem as it could uncup when dry but either way, a lot of it will be chiselled away and it will be invisible under the floors. Regards Vaddoc

Hi Noel I ve been using Rhino for many years. The real objective is to get a smooth (-ish) outer skin. To do this, you need to first define the rabet at stem, keel and sternpost, define the edge of the transom and the sheer line. These are the boundaries of your outer skin (surface of planking). Then draw all your lines, fair them (ask the computer to do it), then choose the most promising and use these to adjust all the others. Then again choose the most promising lines and try to get an outer surface. When you accomplish this, you are pretty much done. You can get any frame of any thickness including bevels by simply projecting vertical lines to this surface. However don't get too obsessed with CAD accuracy, it is very difficult to transfer it to cut wood as I am actually finding out as we speak! Regards

Long time no see Patrick! Nice to have you back. Sapphire came out fantastic, too many lovely details, took a while but I finally figured out the two level engine room. Jewel of a model Vaddoc
