Lol, Carl this would mean going to waste the 150 m of rope I spent weeks making! Maybe best to press on...Indeed, Mark, not all countries are continents!😄 In England we are like sardines in a can.

I did a tiny bit of work today but I managed a breakthrough! To complete the rails, I needed discs made of brass at 7 mm diameter with a central hole of 2 mm. I looked for brass washers but could not find them in these exact dimensions. There are Jewellers tools that cut discs of any size but are expensive. I ve been scratcing my head for days now but finally I figured a way to make discs from brass sheet. Needs a fair bit of tools but nothing too specialised. I used the Dremel bit for mounting grinding discs, the screw has a diameter of 1.3 mm. I drew 7 mm circles in thin scrap wood and drilled a 1.3 mm hole in the middle. I cut small pieces of brass with a hole in the middle. I sandwitched it all, mounded the assembly on my cordless drill and started grinding against the rotating disc sander. The result was excellent. This is a process to make a few discs, not for mass production. I opened the hole to 2 mm on my drill press. This needs care as it is easy to make the hole off center This is how each rail is supposed to be, The shaft, the disc and the sleeve at the bottom will all be soldered together. The shaft will be glued through the deck and there will be 4 brass nails through the disc and into the deck. The next photo shows scrap pieces but the final rail will be something like this.

Mark and Carl, it is a BIG baby! Even as a half hull! I think after completion I will take the masts down in all my models and pack them away, to come out in 20 years time... Bedford, I tried the hairdryer and it seemed the wrong tool for the job. The heat gun came in and it was much better, more controlled and consistent. Safer as well as it was the admiral's hairdryer!

Just caught up GL. Great news she is safely back. The boat looks fantastic, I enjoyed going through the planking very much! I am surprised that you had so many straight edges and so little spilling was needed. This is a very elegant hull, pure wood poetry! Bad luck with the crushed wood. 2.5 mm strips can be very hard to bend into place. Did you use any heat? You may have mentioned it but I must have missed it, what wood are you using for the planks?

Well Keith, the Yawl is I think next on line but at 1:10 scale it will be equally huge so the Deben needs to leave the shipyard first (and go where? I do not have the answer)

Thanks GL I used Beadalon wire, I think this is 0.65 mm. This is a great wire as it is encased in a plastic transparent wrap. It is served with ordinary black thread in my home made serving machine. Brass electric wire crimps are used for thimbles. The seizing in these is beadalon crimps blackened with black gesso, as they were made a long time ago but now I would use the smallest size fishing crimps wrapped in thread-this gives a more elegant result.

Hi from Azores and thank you all in advance

Welcome Marco, good luck with your boat! -
I think maybe another update might be in order as I was allowed to spend quite some time in the garage. First of all, a photo of the finished belaying pins. They have a coat of Tung oil on but the colour of the wood barely changed. I also took a photo of my drill inventory-part of it at least. You can never have enough drills. I did an experiment with seizing the lines. This is wire rope, seized with black thread and encased in shrink tube. The crimps are fishing crimps cut in three. It looks ok I think. One side done. Note that the ropes are not touching but I think after the crimps have been seized with thread they will come closer together. I attached a piece of wire rope to temporarily hold the spreaders in place. The other spreader was badly attached so I had to remove it, fill the pivot hole and re-drill. A few more photos, the boat is large and is difficult to get good shots I also installed the forestay. The bowsprit had taken some nasty bumps over the last few months and I noticed it was loose. I glued it again but I must remember to be careful. With the bob stay on, it should be more secure. Suddenly it feels that the end is very close! A couple more photos

Thanks to all! Deuxey, the shafts on the pins were temporary to allow spinning of the heads for shaping. The pins now have very long shafts that will be cut to length later on Keith,making shackles is easy and actually fun! You will find very useful the thin grinding discs that Proxon sells to cut and shape the brass. Mark, I have drawn up the rigging (most of it anyway) except for the sheets for the jib and staysails-no idea how these will be. There is always the chance I ll need more than I have. I was not aware it is called "becket", learned a new word! Regards Vaddoc

Many thanks to all for your likes and comments. Like many we are not allowed to leave the house so plenty of time to work on the boat! I ve made lots of blocks, many more than these in the picture. I hope they will be enough, making blocks is very complex and time consuming and I would not want to go back to it. I also made two hearts for tensioning the stay sail. I had to make them 4 times before I was finally happy. I then made some belaying pins. I do not want to buy wood at this time so I used whatever I had. I found a 3 mm dowel in my stash, I think it is Birch and used also toothpicks. It was a bit tricky to drill and then shape it but I used a wooden peg which worked very well. I then made the reefing comb, again fully functional with brass sheaves. I then finished and install the spreaders and then attached the 3 pairs of shrouds with shackles I then polished all my shackles. I think they will not be enough but making more is easy and relatively fast. In the end I used CA glue to secure the pin Now, to attach the shrouds and define their length, the mast needs to be up and somehow secure in place. I used scrap wood to secure it in place. I then made some templates from scrap plywood to hold the eyes in a fixed position The (dreadful) figure is 1.75 cm in height. It looks a bit out of scale, I think I ll need to recheck things. On the other hand the Deben is about 7 m long so it is not a big boat. There will be pin rails on the shrouds and I roughly checked the height the need to be placed at for a comfortable reach I will use black shrink tube as Michael suggested earlier in the log, I think it is a very elegant solution. I also got some fishing crimps which I cut to size and should give a very tidy result. However I need a heat gun which I ordered. So waiting for the gun to arrive, I started work on the rails. These proved very fiddly. I need 8 and after I had spent hours making them, I managed to ruin them all by carelessly drilling at random places for the second rope to go through and not parallel to the first rope I realised my mistake after I had marked or drilled all 8 pieces and run out of brass rod. Next day however, I thought of just soldering a piece over and re-drilling. There will be more pieces soldered to the base so I think in the end it will look fine This was good progress and I think I should be able to do a bit more work this week

Welcome David, from the other side of the Atlantic!

This is just amazing. Getting those eyes done on the brass straps is a herculean act on its own.
-
Maybe just use thin brass or copper wire, served with thread around the block to look like rope, but bare beyond and blackened. A couple of turns will secure the wire/rope to the block
-
Dear all A small update, mainly to keep my log from going into complete hybernation. I finished the second bunch of blocks and then I put a coat of Tung oil on. They came out fine. Without Tung oil And oiled. The block that has the rope on is actually wrong as it is upside down so later on I had to redo it Making these blocks is really gigantic work but one that can be done at the sofa or the dining room table. I now have to attach the ropes. A few months ago I realised that copper wire served with white thread does a much better job imitating rope. I soaked the "rope" with CA glue to keep it from unravelling and to stiffen it up a bit.q A couple of close up photos, the first two show the block that was upside down. I now work 6 days a week + often doing a few bits and bobs on Sundays and with the kids and all there isn't really any time left. C'est la vie!

Wow GL, I have not been able to visit for a while but you have made good progress! Very nice joinery, nice fairing of the frames as well. Another thing you seem to have tackled with ease is the curvature of the deck beams-I struggled with this myself. Did the original boat have only one pair of stringers on the inside the frames?

Bench Top 5" Disk Sander

I foresee these sanders achieving the same legend status as Paul Sellers' recommended chisel set! -
Bench Top 5" Disk Sander
vaddoc replied to DocBlake's topic in Modeling tools and Workshop Equipment
Great price for the Lidl disc sander. It is a bit small but for the price unbeatable. I made a disc sander years ago with a very old, much used corded drill, some thick plywood and timber. I used a £2 regulator for the speed and made the disc from MDF. I converted an arbor I bought cheaply. I chose a diameter of 200mm and I use 120 grit that lasts for ages. Perfect functionality It died after a few years of hard continuous use, I got another cheap drill and still going strong. I also sharpen the kitchen knives there! But for the price, definitely this sander makes a lot of sense. -
Bien venue Besson! Je ne pas parlez francais depuis 1986 mais ca est pas de probleme! Vraimant, ca est un forum charmant. Did my best Allan! Vaddoc

So, I did a massive amount of work and made quite a few blocks in 2 sizes. They are all fully functional with brass sheaves, they just need a coat of Tung oil and their ropes. However, a lot of this work has actually gone to waste, at least for this boat! The reason is that I thought I would need mostly double blocks. Today, I started drawing the rigging arrangements, each part individually and noting the blocks that would be needed. They are mostly single blocks and a lot of them! That means another 2-3 weeks of work on the dining room table... Another issue that I am not sure how I will overcome is that there will be an amazing number of rope ends to be tied somewhere, a cleat, belaying pin or other. Either I will need to add belaying pin rails to the shrouds (if feasible as the middle one due to the spreaders is offset) or a rail on the cabin top. I will of course also need to pepper the boat with cleats. I think the end of this journey may not be that far!

I do Bob, but my models are large and do not live in a case but are temporarily-permanently stored wherever there is space and are moved. I know, not good, in good time this will change. Also, the hull is the first to make and paint and then on it will take years to finish the rest so the hull will have a hard life tilting, scratching and bumping all over the place. I have an old model that had the hardest of lives, spent his life in shelves under direct sunlight constantly falling of its flimsy base, hull is 0.8 mm plywood with automotive primer, humbrol acrylic spray and humbrol enamel varnish on top. Still looks good! I d say Moab, just use the thinner the company offers. Cheap and much better than homemade ones or pure water.
-
Acrylic paint is not tough at all and needs some protective finish. Humbrol gloss varnish is great and can be brushed (on cured acrylics also) with great results but is enamel based. A few years ago I tried Valejo water based acrylic varnishes but could not make them work. At the time I also tried the Valejo polyurethane varnish which I did not like. However, I tried the newer Valejo polyurethane varnish which are different and improved and this time I had very good results with a brush. I could not find any info though whether it should be diluted and what with. I think in the end my conclusion was to use water but not too much otherwise it breaks down. Application is the same as the paint but the self levelling properties are even better than the acrylic paint! I think 2 coats 4 hours apart or something similar. I also think they claim it will not yellow over time. The matt varnish needs very thorough stirring and quick application afterwards with minimal brushing and even then the matt particles might spread unevenly leaving brush-like marks. Still, enamel varnishes are much tougher
-
Just to add regarding the arrangement of planks at the stem, that is being placed as high as possible. There might be a connection with the issue of the "exaggerated sheer" (I think this is the term) It is possible when designing a boat, although the sheer is fair and appropriately curved, when the actual boat is finally built, the sheer to appear flat at the bow. This is just an optical illusion due to the size and flatness of the boat and to avoid this, it is recommended to increase the curvature of the sheer at the bow, thus having an "exaggerated sheer". Maybe this is why these people suggest to push the fore end of the planks higher, to get a more pleasing run of the planks.

So, back to work on the Deben! I think I should be alright having made close to 80 shackles, but I will need also blocks. I had decided from the beginning that all blocks would be fully operational with brass pulleys. I need to make many and they take a very long time to make! I am making them pretty much as the full scale ones are made and really they are complex pieces. I ve made 40 that still need sanding to dimensions and to shape, grooves cutting, Tung oil and then the ropes attached. I think I ll need maybe another 30, huge work for something that no one will ever suspect is there! A few photos:
