HMS Ulysses, a Roebuck class vessel. Built using the Hahn method
Adding new pieces for the building board jig.
Frame layout added
Some more modificatopns to the jig
Hi Kevin,
Very precise work, nicely done. Is the keel, stem and knee of the head temporarily in place? The reason I ask is that it would be a lot easier to taper the knee of the head before everything is assembled. From The Shipbuilder's Repository and The Elements and Practice of Naval Architecture, for a 44 gun frigate, the head reduced from 14.5" at the stem to 4.75" at the forepart, which is quite noticeable. I noticed in my Hahn book that he ignores this prominent feature except where there does appear to be a slight taper on his drawings of the Alfred and the Cromwell.
Happy modeling in 2025!

The keel , stem and stern are all temporary to assist in figuring out how to build the jig. The stem will be tapered and as you can see i can adjust the clamps to cater for the tapering. I added the alan key bolts with 1/2” movement on both sides of the centerline. This was my latest modification. I am not starting this build until the Thorn is complete. This should between June to September next year. I cant build two models at the same time. I wanted to spend time developing the jig so that i do not start with any errors that can accumulate and cause headaches later in the build.

Following the build with much interest Kevin. 
Very clever idea Kevin. Something for me to keep in mind for the future. Nicely done!

Looking forward to watching this progress. Big project no doubt.

I wish you a lot of fun with your new project. I am little bit surprised, that yougo back to the less detailed Hahn method after the success with your sloop Thorn.
