After making frames 6 and a pair of frame 7s, I decided to start assembly. I installed glue blocks to the bottom of the sponson insides and engine bay walls as well as the inboard end and bottom of frames 7. To keep weight down in the afterplane, I made frames 5 and 7 out of 1/32 ply rather than the 1/16 ply everything else except the transom was made from, it was 3/16". In the end, I ended up puting both sponson insides, both engine bay walls, the transom and the previously mentioned frames 6 and 7 together using West Systems 105 resin and 209 hardener while at the same time installing a resized and cut aft bottom. The bottom was installed to keep the hull square during the rest of the build. When the epoxy had cured, I added glue blocks to the frames for attaching the nontrips as well as adding frames 5 with it's glueblocks. The glueblocks were all installed at 45 degrees to match the angle I used on the ends of the transom as again drawn on Roger's plans. I included a third picture showing how the frames were clamped together taken from the kit build I ended up doing for the wife(build is being documented in another thread)
