  1. People build models for different reasons, and chances are that when you start your project you have an idea of what you want it to look like when it is finished. It is is entirely possible to built a model shown under construction that satisfies your reason for building it. The best example of this that I know of are the models in Harold Hahn’s exquisite shipyard diorama. There are also models in the NMM collection that are built to demonstrate aspects of shipbuilding technology that show only parts of ships. In my case, I consider a model to be finished when it goes in its glass case. Roger
  2. You don’t mention the metal alloy involved but if they are the usual white metal parts offered by kit model suppliers it’s probably a good ides to prime them. If the white metal contains lead, it can oxidize to a white powder. Priming supposedly limits this. Roger
  3. Maury, Thanks for posting this. The Naval architecture concept of tonnage developed from the large barrel that you show called a Tun. In the 1500’s wine was a major commodity imported by England and the king, either Henry VII or VIII, needed a way to levy taxes associated with shipping. The easiest method was to rate a ship by the number of Tuns that she could stow. This morphed into a system where Tunnage could be predicted by multiplying length x width x depth under the main deck and dividing the result by 100. This concept still survives to this day but the calculations are more complex. Tonnage is therefore a measure of volume, not weight. The weight measurement Ton also derives from the carriage of wine as a Tun of wine weighed 2240 lbs, one “long ton.” Roger
  4. The amount of detail incorporated in such a small scale model is remarkable. Nice work. Roger
  5. Joe, If negotiations fail, declare eminent domain. Cite Covid19 emergency. No one is welcoming house guests these days. Roger
  6. A good marketing ploy would be to send OC a bottle of their paint to try along with their topcoat. The cost, not price, of a bottle of acrylic model paint must be pennies, or pence. Roger
  7. I have read that Dornier produced a Diesel powered bomber that was apparently satisfactory. Diesels are not usually associated with avaiation. Is this the plane? Roger
  8. Hand tools! You need a plane, a spoke shave and some chisels. A gouge is also very useful for heavy material removal to shape the stern. You also need sharpening materials. These can be as simple as 600-1000 grit wet dry sandpaper fixed to a dead flat surface. A glass sheet will do. A good craftsman uses a mallet to drive his chisels and gouge, not a hammer. A homemade mallet works fine. A coping saw with a package of wood blades will also be required. With the possible exception of the gouge all of these tools should be available from a hardware store. Presumably you have a “lines drawing” showing the contours of the hull; like a topographic map except in three views, a top view, called a plan view, a side view called a sheer plan, and an end view, called a body plan. The body plan can be confusing as one side of the plan is viewed from the bow and one from the stern. You will use the sheer plan and the body plan to cut templates. You will need a template for the bow profile and the stern profile. You will also need a template for each body plan station and you need to mark the corresponding stations on the hull. A hint- look on a body plan section within the vessel’s parallel midbody- that long straight hull section. It should indicate the bilge radius. If to scale, it is an even fractional radius; 1/4in, 3/8in, etc you’re in luck if you have a friend who owns a router as this is easily cut using the correctly sized router bit. To shape the stern, I would project vertical lines representing the sternpost on each side of the hull block. These vertical lines are also vertical projections of the point where the two lines that you have drawn on the bottom of the hull come together. Also draw a horizontal line around the stern at the level where the vertical sternpost intersects with the curved stern. Now, using the coping saw, carefully cut along these lines. Your hull will now have a rectangular notch cut out. Now using carving tools start removing material checking often with your templates. And remember- Bondo is your friend! Roger
  9. Yeah, right! A good excuse. Today business is all about branding. It is interesting to learn, at least in the USA about the many projects made by one manufaturer who then sticks different labels representing different brands. Roger
  10. For a modern steel built vessel, I’d just carve the hull. I make two half models from laminations shaped from buttock lines. A ship like this does not have a pronounced keel like a sailing vessel but with this type of construction you can sandwich a brass or if you must, a plastic center plate between the two half hulls. This helps to preserve the bow and stern profiles. The benefit of carving two half hulls is that you now have a flat surface, the vessel’s centerline that can be laid on a flat surface to check contours with templates. I drill holes for locator pins in each half hull block prior to shaping. Once the half hulls are shaped these automatically ensure accurate alignment. If you try to build this as a planked POB model there are some areas like the sharp bilge radii, the bow, and the stern where planking will be difficult. Furthermore, once your planking is done you’re going to have to hide it by filling the seams with some kind of goop, with concerns about them later opening up or by covering the whole thing with fiberglass, a messy job. Roger
  11. I haven’t checked in your project lately. It’s really coming along nicely! Roger
  12. A very serious discrepancy was a lack of armor on horizontal surfaces. Where the Confederates had located forts on high bluffs, several boats were disabled by plunging fire that hit boiler steam drums. This was not a problem unique to the gunboats. Fifty years later ( and still later with HMS Hood in 1941) the Royal Navy was still confronted with inadequately protected horizontal surfaces. Roger
  13. I do find that on metal figures, adhesion of the acrylic paint to the primed surface is not great and it is necessary to touch up edges where the paint has worn off while being handled during painting. A coat of Dulcote after painting seems to provide protection. I have metal figures that were painted with Floquil paints in the 1980’s and were neither primed or sealed with Dulcote after painting. They look like they were just painted. Roger
  14. I don’t know OC. All of my figures are pewter or lead (the older ones). I have not tried a brush on primer. The metal is relatively inert vs the primer. Plastic introduces a new variable. What happens if you apply the colors without priming. Roger
  15. OC, I have been priming my pewter and lead figures with Tamiya fine surface primer. I have been painting them with Acrylic paints- both “Army Painter Warpaints,” sold by Amazon and Vallejo. I have detected no difference between the two brands and they seem to be compatible with each other. I let the Acrylic dry for at least 24 hours, then spray the complete figure with a light coat of Testor’s Dulcote (Outdoors as my wife objects to the smell). I believe that Dulcote is a lacquer. I have had no problems and it dries with a nice matt finish. With the acquisition of Testor’s by Rust-Oleum I am concerned that Dulcote will be discontinued. With that in mind I recently bought a can of Rust-Oleum’s spray matt finish. We’ll see how that works. Roger
  16. My limited knowledge of the Battle of Waterloo dates back many years when I got excited about painting Airfix 54mm plastic figures so my question may be “off the wall” Why did Napoleon expend so much effort on attacking La Haye Sainte? His mission was to rout the Allied Armies. Had he succeeded in breaking Wellington’s main battle line this outpost would have been untenable. Was it so heavily manned to constitute a viable threat to the columns attacking Wellington’s main line? Roger
  17. Brian, Doing the research, figuring out the building process, and sticking with the project through completion is a huge part of scratch building. Without a compelling personal story it is easy to get sidetracked and the uncompleted model gathers dust. Thanks for sharing your story. Roger
  18. OK, you’ve got the model kit. You’re not going to get your money back. There is nothing that you can do that will cause the supplier to change its behavior. Build the model! If the result is disappointing chalk it up to experience and use what you have learned next time to build something from a legitimate supplier. Keep in mind that the kit represents an imaginary vessel. Roger
  19. Many years ago following retirement my father joined an EAA club who were building an airplane. Although the fuselage was welded tubular steel, the wings were fabric covered wood frame. My father had experience with this type of construction so he agreed to build the wings. The FAA specs required the spars to be made from clear straight grained Sitka Spruce. He located company that made ladders for Fire Departments. These ladders that had to be light, strong, and I suppose non-conducting and were, therefore, made from Sitka Spruce. He bought the spar material from them. Just a story. I’m not suggesting ladder manufacturers As a lumber source! Roger
  20. For those us that still draw lines drawings by hand, Sita Spruce makes great splines. I saved all of the offcuts several years ago from a canoe restoration project. Roger
  21. It appears that we are confusing two separate issues. How to orient the grain How to set things up to saw the planks The first will determine how well the wood will bend. If there is “grain run out” in the plane of the wood being bent the wood is more likely to fail. Grain runout means that the grain, not being parallel to axis of the plank reaches the surface. Since the grain boundary is weak the wood separates at this point. Choose the straightest grained pieces that you have. The second has no bearing on the wood’s flexibility. It is a matter of which technique you feel more confident in using. I would rip slabs to the 5mm dimension and then slice .5mm strips but if you can do it the other way OK. Roger
  22. Mounted where they are the rudders would have been ineffective. A better choice would have been to move them inboard where they would have benefited from the fast moving water from the paddle wheel, but that would have posed a structural problem- how to support them. The inboard, center location of the paddle wheel was likely an attempt to shield it from gunfire. Roger
