  1. Lots and lots of info on MSW, some dedicated threads as well, a wealth of info. Test on scrap wood, not the model! I would however suggest to buy good brushes straight away - System 3 if still around are great Modern paints are so good that with a bit of practice and attention you ll have excellent results Vaddoc
  2. @allanyed This is it pretty much Allan. Actually the hole left when the screw is removed is smaller and can even be filled with a smaller 0.7 mm wood nail dipped in PVA (or copper or brass wire dipped in CA which is a much faster process).
  3. In my experience, there is a world of difference between cheap and higher end CA glue. An issue to consider with any glue is the degree of contact between the mating surfaces. PVA needs excellent contact and pressure, not always possible with planks. CA just a bit of contact as it is incredibly strong. Thickened epoxy will bridge any gap but is very messy. Expanding glues like the amber Gorilla one are even messier. I would not trust contact cement for this task. Hide glue I have no experience with. If I was gluing planks to frames I d probably go for CA. Have debonder at hand though to detach your finger from your eyelid!
  4. I use 1 mm screws which I then replace with wooden nails. In the past I ve used brass wire dipped in CA glue. All planks in all of my models are fastened this way - no plank is glued. Once I thought of threading brass wire and using it without glue but the amount of work needed would be far too huge.
  5. Dear all A bit of progress but a also a bit of a milestone: The deck is done! Still needs lots of work, treenails, sanding, caulking etc but the arrangement seems ok - I hope in the end it will look more tidy. The wood is maple but has a different color than the maple used for the inner planking. One of the planks aft stands out as, not sure where I cut it from but it needs to be replaced. Take care all Vaddoc
  6. Thank you John and Nils @Mark Pearse Mark, the wood is already sealed inside and out! It has reduced the movement but not completely. Maple that I ve used in the past, does not move at all. Isn't boat building fun! Vaddoc
  7. Dear all Many thanks for your comments and likes. @Dr PR You are right re: epoxy Phil, but I ve used beech wood - couldn't have made a worse choice! I ve lost count how many times I have had to go back to the hull. It keeps on changing shape, new cracks appearing, planks shifting, it follows the change of seasons and when it reaches equilibrium with the ambient moisture the planks go walkabout. I am waiting for the weather to get warmer so I can paint and varnish it and then leave it to cycle through its moods. For now, I ve just used some more filler - Ill sand it smooth tomorrow. I am using Osmo filler which is wonderfull stuff, run out of beech colour so using colourless but I ll prime the hull so it does not matter. I finished the inner planking and sand it smooth - ish. I ve been scratching my head for some time now, not sure how the floorboards should be arranged. There is a substantial curve at the sides where the floor meets the side planking. Not sure how this would have been made In the meantime, I made another model with my 7 year old daughter - a school project. The photos are terrible but you may just make out the cotton at the top of the chimneys. We really enjoyed the juice previously contained in the hull. Till next time Vaddoc
  8. Ok, so I ve used this sander a bit and these are my thoughts. Really quiet, this is a massive advantage. Also the 150 mm usable disc is very useful. The guide is solid and totally usable. Now, the negatives. There is a run out of about 1 mm at the very edge, this however is not a huge issue as the disc rotates fast and also nearer the centre this run out reduces a lot - overall, it would be nice to be dead flat but it is not an issue for me. However, it comes with 80 grit paper which I changed to 120. Oh dear! This took me 3 days and was a Herculean task. The disc it comes with is some kind of very high industrial quality disc, with a thick plastic backing. Unfortunately all of the glue was left stuck to the disc which is not smooth but rough. I destroyed my finger tips rolling off the glue. Heat did nothing. Isopropyl alcohol and methylated spirits also were ineffective. Acetone however did the job well. I used cheap toothbrushes and finally all the glue came off. I assume and hope the glue of the replacement paper discs will be less vicious. I put the new paper on which did not stick well and comes off if left unused. I may not have allowed enough time for the chemicals to evaporate or not degreased the disc well. As I am still traumatised I just press it it back and ignore it for now. Overall, a good buy and a good tool, I do not regret getting it and I ve been using it a lot. Regards Vaddoc
  9. @håkan, @Jim Lad, @Mirabell61, many thanks! To all that hit the like button, many thanks as well! A bit more work done, I feel I understand the boat better now. I made the frame for the fish well, needs its veneer to be added on. I also added most of the inner planking on the starboard side. It went really well, I only had to spill the aft part of the lower plank. There is a bit more planking left to do towards the bow. Screwing and drilling at such angles is pretty difficult, mainly at the bow. I also cut a piece of wood for the breasthook/small deck, it will be sanded curved later on after the sheer shelf is added. The inner planking is maple, so will be much easier to sand than beech. At 1 mm thick it allowed generous edge bending but I do need to be careful when sanding. Vaddoc
  10. Ok, time for a wee update! I have not gone into hibernation and have done a bit of work, just did not have the time to take photos and post the progress. A lot of head scratching though, it's been a long time since I did the 3D plans and I had forgotten how everything come together. I also had forgotten that I ve used beech for the hull and generally cut a few corners in this boat. Now these are biting back! I simply cannot understand why I used for the frames the cheapest, nastiest plywood ever made! So, first I had to deal with the hull and the dancing/shrinking beech wood. I filled the cracks but brought the boat inside as it was freezing cold in the garage. Yep, the wood contracted again and the sims opened once again! I filled again, sanded, filled, sanded... I have now settled with Osmo water based filler and Decoart water based sealer - excellent products. So, after lots of filling, sanding, scraping etc, the hull looks decent, is sanded to 400 grit and is sealed inside and out. This took time, effort, a few lungfuls of dust and lots of cursing. Ok, time to free the boat from its cradle! Now, the boat needs inside planking, bulkheads a bit of deck fore and aft, floor boards, the engine box, the fish well, a rudder, and this elusive vertical rudder. So here it goes: I could not remember how all were supposed to come together and it took me a long time to figure the boat out again. I am still not sure how the floor boards and inner planking should be arranged. In any case, I installed the sheer clamps and the two bulkheads fore and aft. I had to deviate a bit from the plans due to my corner cutting. I also cut several of the frame extensions and made two braces to make sure the hull does not loose its shape. I also bought a new water stone 1000/6000 and honed again all my chisels - they are now truly razor sharp. I also did all the kitchen knives including the serrated bread knives - all now very sharp! Much to do and at some point I must paint the hull. I have no doubt the beech will find a new moisture equilibrium and the sims will open up again so it needs to be done asap but it is -2C in England currently so painting will have to wait. I 've decided to use enamels and top it up with enamel varnish - all brush painted. Have not used enamels in many years! Till next time, my very best wishes for the New Year! Vaddoc
  11. If I need really flat strong plywood, I make it my self. If I need 6 mm, I take two sheets 2.5 mm each on a flat surface. Thicken epoxy with gypsum, spread onto one sheet, cover with the other and put something very heavy on top. 12 h later I get very flat, very rigid 6 mm ply.
  12. Try Rennaisance wax. Invisible, dead easy to apply and will keep them shiny for ever. This is I think what museums use. My experience has been very good - I have brass pieces stay shiny for 10 years now
  13. Allan, if you google "1mm Philips self tapping screws" you ll get lots of results. I buy mine from Aliexpress, different lengths with 5 and 6 mm more useful. Last time I bought 20k! Best is to use 0.8 mm drill. The stainless steel are better than mild steel as the head resists deforming which can make removal impossible. I have had difficulty recently finding good quality proper hard stainless steel ones (if they are non magnetic they are the good ones) Smaller screws are extremely expensive available in very few specialist shops. However, you can thread brass wire and use it to screw things together but it is very labour intensive, vaddoc
  14. 1 mm screws can be useful. I ve used tens of thousands of them - replaced by treenails later.
