Frame 35 fit pretty squarely in the keelson. However, one of the frames a bit further fore (#33 or 34 maybe, I'm not by the ship to check) was not touching. This is super annoying because I checked a bunch of times but still didn't see it.
I took the opportunity to wire brush the frames on the port side to clean off most of the char. Then I took a stab at fixing it.
I filled the gap with a small piece of wood but I'm not really happy with it. The steps still sit a little too high relative to the frames fore and aft. I could dissolve the glue and try to reseat the frame but then it seems like the steps will sit too low.
I'm not really happy with how the stern frame steps (joggles?) came out either. These were the first ones I did and they are a lot sloppier in comparison to the rest. So... not museum quality. But this is an extreme closeup and looks pretty incredible for a piece intended to sit in the home.
Next, I noticed that one of the frames around 20 was not parallel with the rest. Funny how you start to notice more detail as you get a little experience (this is my 2nd ship, the first being the beginner model, Swift 1805).
The only solution for this was to inject acetone into the space between the frame and where it contacted the hull clamp and inner planking. After a few minutes, the upper two pieces broke free from the rest. I cleaned off the dissolved glue and clamped it back in place, parallel with the rest. It's still drying so I don't have a photo yet.
Next up are lots of little dried globs of Weldbond like these. To deal with them, I'm wiping acetone on with a paper towel and then gently scraping off the remnant. I followed this up with a little light sanding.
