Thanks to everyone for the likes. Thank you, druxey. Your explanation was much more explanatory than anything I would have said. The fashion piece was a pain to fabricate because of the compound curves. But by following the little-bit-at-a time approach, I ended up pleased with the result. As you can see in the picture, the model does not have a fashion piece. In fact, the aft ends of the hull planks are unusual; typically the lapstrake would have gradually diminished to a smooth surface.

It has been almost two months since my last post but I have been busy doing small projects. Having recently completed a capstan in 1:16 scale, it was time to duplicate my efforts at 1:48. If you have purchased the Capstan Project, I used the approach outlined in the advanced version. The capstan on a ship of this size and from this era has five whelps and six bars. I turned the spindle in a lathe and then used a mill to make it ten-sided. The pencil marks are to help the edges stand out. The whelps were glued-up as a sandwich; the thickness was the maximal thickness of the whelp. The sandwich was then glued to a block of wood, which was put into the mill vice. The face was milled and the whelps were separated by soaking in isopropanol. I made a few extra to allow for mistakes. The whelp is wider at the bottom and on its face. The final shape was achieved with a sanding stick. The drumhead was made from four semicircular pieces and a cap. I used thin adhesive-backed copper sheet as the iron ring. I used liver of sulfur to give the copper a patina. After the whelps were glued to the spindle, the chocks were made and installed and the bolts were installed. The iron ring looks much better than the photo would suggest. And the final result... The next item I needed to address was the decorative molding. The plans show the molding at the level of the bottom of the gunports. The model shows the molding halfway up the gun ports. The plan shows the bottom of the oar ports raised by the width of the molding. The model shows them at the same level as the gun ports. As it turned out, I (accidentally) built them at the same level, as shown on the model. If I left the molding where it is seen in the plan, it would have gone through the oar ports. So my choices were to rebuild the upper works to lower the oar ports or raise the molding, as seen on the model. I went to the RMG site and looked at other models with oar ports; they were most commonly positioned at the same level as the gun ports. Therefore, I decided to move the molding instead of the oar ports. The ship has eleven swivel gun mounts on each side, although she only carried eight guns. These were located per the plan. They were notched to fit over the rail. Bolt holes were drilled. The metal work will be installed later. The cathead and cathead knee were made next. The cathead was sawn from a single piece wood. Two sheaves were installed. The cathead knee was made up of three pieces, as seen in the picture below; the final shape was attained with sanding drum and disc. The cathead and knee were then temporarily installed. No finish has been applied to either the swivel posts or the cathead. As you can see in the third picture, the tops of the swivel posts have not been shaped yet. They will be horizontal across ship and will parallel the shear when seen from the side. Also temporarily fitted are the first oar port and gun port covers. They will all be hinged horizontally. Other small items which have been installed are the cleats (three per side) and the mast coats. The entry ladders, pumps and capstan are temorarily in place.

NRG VIRTUAL WORKSHOP - AUGUST 21

Thanks for being there. -
Thanks for joining us this morning. The redo looks much better. Just remember, isopropanol goes on the model; ethanol goes down the hatch.

Justin, three sheets have changes in them. The changes are referenced on the pertinent sheets. Intermediate version- Part 104 on sheet 13, Part 012 on sheet 15 and sheet 23. Advanced version- Part 104 on sheet 13, Parts 012 and 013 o sheet 14 and sheet 23. -
Tom just brought to my attention a problem with the printed plans. The plans themselves are correct but the scale on Part 104 (and possibly others) is off. I will go back and double check everything over the next few days. The takeaway lesson here is that you need to build from the measurements, not the printed page. I can hear the four engineers who reviewed my work now...they did not want me to put any scale on the drawings for this very reason.

Paper wrapped around the bit works also.

I am unable to give you any insight as to the purpose of the heavy rings. Sorry. -

The bollard timber heads have been remade. As I was making version one, I knew there was something wrong but could not figure it out. As druxey stated, the inner and outer (athwartship) faces of the bollard head runs parallel to the keel. I have made an opening in the sheer rail for the timber rather than gluing it on top, as I did in version one. A thin piece of boxwood was bent around a dowel and used to fill simulate the bollard timbers alongside and below the bowsprit. Treenails in the grating were simulated with a punch. A pencil was twisted in the depression to represent the treenail. Bolts made of blackened brass wire have been added to the bowsprit step, bitts and anchor lining. Mast wedges for the fore and main masts were made up from four smaller pieces of castelo, glued together. These were turned on the lathe. The opening was made using a mill with a rotary table since I did not have bits the correct diameter. The multiple wedges were simulated with an 11 blade. The skylight was glazed with sheet mica. Most of the external details (other than the channels and deadeyes) have been finished. While it was still safe to hold the hull upside down, I installed the horse shoes, ribbons and gudgeons. The horse shoes and ribbons are left over from the photoetch sheet once sold by Admiralty Models. Recesses were carved in the stem, sternpost and keel for them. The pintles and gudgeons were made from brass square stock, strips and wire. They were silver soldered and blackened. I used the method shown in TFFM. The sequence is shown in the diagram. First the brass rod and strips are cut to length. Next, slots are filed into the brass rod to accept the strips. They are soldered and the face of the rod is shaped. A hole is drilled near the front. For the pintles, wire is inserted into the hole and soldered in place. Once I was sure that the rudder could be unshipped, I removed it for safe storage. Question: would a ship of this size have a spectacle plate or would some other way to secure the rudder been used? There is no spectacle plate shown on the plan or the model.

About the NRG
If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.
The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.
The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
