I've completed construction of frame #1. The tabs on the sides are oversized so I can trim them when I install the stringers and planking. There's been some discussion on the forum about gaps at this area so I figured I'd be ahead of the game a bit. I've marked where the stringers should go. These odd shapes were scrap from the holes cut in the stem spine section.I Won't coat the frames in epoxy until just befor I glue/screw them into place on the building jig. I have also yet to cut the hole for the forward round hatch. Likely it will be 8" diameter.
