  1. I spent some time gluing up the parts. One thing I noticed whilst I was watching the laser cut was that around 2 thirds of the lines would cut with a single pass of the laser. These resulted in nice clean cuts. However, the remaining lines each had up to 10 or more passes which resulted in scorching and small holes from I assume reflections of the aluminium grid it was resting on as the beam repeatedly passed over the same path. As can be seen in the two images, some of the joints are spot on. However, there were other joints where the wood had been scorched away from repeated passes of the laser. This resulted in gaps in some of the joints. I have highlighted problem areas in the two images. The scorch mark are obvious in the images I posted above. That is the top side view of the board. The underside was much worse. I suspect the person operating the laser (I wasn't inducted) did not know how to correctly setup for the cherry. I did not notice a setting in the software for wood except MDF or Plywood. I shall be modifying my approach to this piece. I used 1 1/4" cherry and after cleaning the scorch marks and correcting a very slight bow I induced from the glueup, To glue up I will be using pins and a board to hold the pieces flat whilst drying. This attempt though I did not. (I used my Proxxon Planer then Thicknesser to flatten and clean up both sides.) I ended up with a flat stem at 210 thou instead of 250 thou. It shall be remade and I am considering changing from Cherry to another wood that I can source in Australia. Poplar or Huon Pine. I have also attached an image of two other laser cuts I made on the same wood panel. This show the underside though with the scorching. Unfortunately I did not get an image of the stem panel underside.
  2. A little bit of progress on Pegasus. The wales were sanded flush to each other, masked and then tamiya flat black with mlt to thin was sprayed on the wales. There is also one row of the 2nd planking above the wales on both sides. I have yet to decide how to trim the rear of the wales as I don't yet understand the run where they should finish and what shape they should be.
  3. Hi Everyone. I bought the plans and downloaded them several weeks ago. I was contemplating having Chuck send the starter kit to me in Australia. It seemed the easier way. However, I have chanced up a community makers space a few miles away which provides access to laser cutters, and woodworking machinery that I don't have. I bought a block of Cherry a while ago and thought I would see if they could assist with sizing it into 3 x sections by ripping the 1 1/4" slab on a bandsaw. The bandsaw was waiting a new blade so they used a table saw. I sized the slices to 1/4" on their thicknesser. I then used 2 of the pdfs I had for the stem to test out their laser cutter. It has a bed size of 1300mm x 900mm. My little piece was accommodated with ease. One question I have though regards the bulkheads and keel pieces. They are 1/4" ply. That size is problematic in Australia being a metric country. I can source 6mm or with some difficulty 6.5mm plywood. Both are fine? grades for exposed faces in furniture production. 1/4" though is 6.35mm. If I substitute the 6mm OR 6.5mm ply, what issues could be expected further down the build? Thoughts or workarounds?
  4. I shall be posting updates as I go. I have a build log here. I am currently finishing the two layers of the 1mm x 4mm Wales in the kit. This is a problem area for me as I am trying to work out how the Wales finish and are shaped at the stern.
  5. I think this method makes sense to me. It may be what I do on my next model.
  6. Cheers for that, I am being flooded with information from youtube builds, a few of my books, and suggestions here. They all make sense. However, with this being my first build in 40+ years, I plan on this method to try and get just basic techniques down pat. I want to find out the shortcomings and then perhaps look at adapting what I did on this model and then adapt and modify what I did to the next model. I have seen 4 of Chucks videos on shaping the planks. Nice method but I do not have enough info at this stage to go further.
  7. Hmm, I haven't noticed any posts. I shall do a search. Cheers for that.
  8. Thank you for that. I plan on doing 5 or 6 and then remeasure the gap and redo the calculations. The hull will be coppered but I do want to do the best I can to learn the techniques for when I do a hull that is not coppered.
  9. Hi, I will be edge setting and bending the planks as supplied in the kit. I plan to lay down 5 or so planks each side to thee size suggested and then redo the planking calculations based on new measurements. I plan to redo that every 5 or so planks. Regarding the taper from the last bulkhead, I plan on assessing those as I fit each plank. I have yet to come up with a solution so will assess on each plank.
  10. Evening, I am starting to get close to 2nd planking on my Victory Models HMS Pegasus. I think I have the idea of a planking fan sorted out. Does this look a reasonable way to approach this? Do the calculated tapers seem reasonable? I have seen other more involved methods but being my 1st wooden model in 40plus yrs, I think this will do for this one.
  11. Work has continued on the Pegasus. The last few days has seen the 3 strips on each side placed. The stern of these strips needs to be placed securely. So far they are not fixed correctly. These 3 strips each side will have another layer of strip on top. This will then be the wales completed. The 2nd layer of planking will then be tackled. The Keel, Beakhead, and Stem were also located and glued into position. The rear counter at the stern was also planked.
  12. The last few days have been spent filling in the last 2 rows of planks. That was time consuming but satisfying work. There were small gaps in the rows that I could live with. The more planking I did, the more I refined my techniques so the planking got better as I got more experience. The next step was to sand the hull done to give a relatively smooth finish. A few hours was spent on this yesterday hand sanding as well as using my small detail sander to get most lumps out of the planking. This morning I filled the bumps, gaps and problem areas with an epoxy resin to enable me to do finish sanding and to bring the hull to a uniform level ready for the 2nd layer of planking. The next step I have to do though is to fit the beakhead, keel, and stem to the boat. That will then be ready for the final planking to go on. I need to study the correct method to plank the hull. Even though it will be coppered and thus hidden, I still need to do the best I can on this layer so I can gain experience before I do a non coppered hull.
  13. I am now 12 rows in of the 1st planking. As the curves at the bow and stern become steeper, I needed a method to bend planks along the thick section of the plank as well as the thin section of the plank. The planks are 2 mm thick so I used offcuts of 2mm planks to form a bending jig on some spare flat wood I had laying around. I did not measure the curve precisely, I just wanted some curves to test out the jig. With the plank to be bent forced into the channel in the jig, I laid a hot iron onto the jig for a minute or so. This heated the lignin in the plank and softened it allowing it to retain the new shape when it cooled down in the jig. This worked surprisingly well. The idea for the bending jig came from videos I saw by Chuck Passaro? and Ohla Batchvarov. With the plank bent, I then cut a small taper from the bow around 100mm back. I then sanded slightly a slight angle on the edge of the plank. This allowed the plank to sit better against the previous plank. With the bend and the taper, the 3 planks I placed each side went on with little effort. Bar of course the tapered tip of the last port side plank. This splintered due to a nail miss when I hit it. It is visible in one of the images. The planking is not something I ham happy with but it will not be visible after I smooth it all to remove dips and fill holes.
  14. I used heat to soften the glue on the problem joins on the bulwarks and much better clamping to ensure the joints were solid. I have now progressed to 6 rows of planking along with a stealer at the stern. The 1st plank is an issue at the stern but I shall tackle that with water, heat, and clamping. I am just concentrating on the planking technique so far. I tapered the 6th plank at the bow and will see what effect that has on the 7th row.
  15. Evening all, I suspect I have an issue with the fairing of the 2nd last bulkhead at the stern. Putting on the 3rd plank each side and I am finding a lot of curvature is required. I suspect I did not take enough off when fairing the frames. Although, as can be seen in the two images, the 2nd last bulkhead has been faired to the last bulkhead. So, what options do I have? Remove the planks and re-fair the stern or use my electric plank bender or Amati manual plank bender to put more shape into the planks at this area. Thoughts? Brickbats?
  16. Chris, Thanks for that. In Ohlas videos of this model, I see she has scalloping as well but not to the same degree as me. I guess it's time to face the planking now.
  17. I have been having issues with gluing the fore and aft bulwarks on the Pegasus. I initially used my electric plank bender to shape but that put in too much shape to fit. I then soaked them in boiling water for a half hour to soften and then pinned and clamped them to the bulkheads to set in the shape needed. After a day or so I released the clamps and glued the front port and starboard bulwarks in position. I did not clamp particularly well it turns out as the tops of the bulwarks pulled away from the top of the bulkheads. I used the bulb on my electric plank bender to soften the Titebond II glue. I reapplied some Titebond II and used much stronger clamps. I let them set for 24 hrs then removed the clamps. The issue is that whilst the joints on the bulkheads are now ok, along the bottom of the bulwarks on both sides, there is now scalloping between the bulkheads. The joint between the fore and aft section is also now showing a perhaps 0.5mm step approximately. I am considering breaking that joint with the heat and trying to reset the joint without the step. The top of the joint steps out, the bottom steps in. The middle of the joint is perfect... 🤣The bulwarks are 1mm plywood. What I am considering is lightly sanding the scallops to reduce the wave. Just take the tops of each scallop off essentially. The 1st planking is 1.5mm thick and starts at the bottom of the bulkhead. That would absorb some of the waviness. Sanding of the planking should enable me to fair the 2nd planking into making the bulwarks smooth. Does that sound reasonable or is there something else to consider...? I appreciate any suggestions.
  18. The port bulwark is proving problematic. When I glued in place I was certain it was clamped correctly. Obviously not as the bottom of the bulwark was proud of the bulkhead instead of rolling around the bulkhead glued in position. I used my Amati electric plank bender to apply heat to the bottom of each bulkhead, soften the glue and nail the wood into position. The bottoms are now fixed in place as seen in the 1st image. The nails have been removed now. In the second image it can be seen that the top of the bulwark has separated from four of the bulkheads. Heat again and better clamp one at a time or try each one straight after the other? Do I reapply another spread of fresh glue or reheat then just clamp? Any other ideas I have missed?
  19. Chris, Thanks for that. I have just finished gluing the strakes on yesterday. I will be unclamping them later this evening. I got it as close as I could but did place a bar clamp on the two halves to pull the bow together. I found otherwise that they just would not sit tight. Looking later I will see how close I got. I am concerned with a slight wave along the bulwarks lower half as you look along the hull. I pinned the bottom in on both sides then glued and clamped the top of the bulwarks. Today I noticed a slight wave. I shall try and get a picture of it later. I appreciate your advice.
  20. In the 1st image below, I show the strakes that I had bent using my electric plank bender. First time user of this bender. I over bent the strakes and had issues fixing the starboard strake. 2 attempts resulted in me removing the strake both times. The fit was just not good. Lining up the fore and rear resulted in a mid length buckle that I was just not happy with. I took a couple of days off to reconsider my approach. I watched Ohlas video of this part but it only showed the bending then fitting. I had a re-read of the supplied instructions which suggested submerging both in boiling water for an hour. Then, pin the strakes whilst damp and let them dry in position. I did this yesterday with the assistance of my son who would nail the strake whilst I held them both in place. Thay are now dry and will be removed tomorrow. I will let them settle in this shape for 2 days, Then remove the nails and glue in place.
  21. I have been a bit slow this week. I have had hot weather, work, and most importantly, family have been visiting. Not much has been accomplished. I have glued the main deck in place as well as pinned the bow and stern deck in place. I have mostly finished fairing the hull and now just need to finish fairing the decking to the bulkheads.
  22. Work has continued this last week or so on the shaping of the bow and stern. At this stage the build seems ok. Reading the instructions and watching Ohla Batchvarovs video build of this kit is helping me get things moving along. Shaping has had to be done outside when the sun is either very early morning or late afternoon so that I have cooler temperatures and shade to do the work in.
  23. The last few days have been spent cutting some basswood filler blocks for the bow and stern. Being the first time I have used this method. I learnt a valuable lesson. In future, trim as much as possible before fitting them in place. Save hacking, cutting and grinding them to shape with my Dremel before I can use my Perma-Grit Tungsten Carbide coarse files top start shaping the bow and stern. So far, the starboard bow has been roughly shaped.
