Well, I’ve been thoroughly getting my ass kicked.
After taking the time to make support pieces from regular insulation styrofoam and then transferring them to structural foam, the structural foam doesn’t have the compression that insulation foam does, so I ended up making them multiple times.
Previously I’d push down on each part to set it in its place, but it was compressing on the boat surface AND the pod surface, making it seem like it fit, but really it was just confirming to the cracks and crevices it needed to. Remember, the inside of the pod is a laminated part (B-side) with irregularities. After grinding lumps and seams out, I had a surface that was more true and would conform to a saw cut.
All I’m going to say is it’s harder to suspend a part accurately in space than you think...
Anyway, each piece is fit and supported to be centered and at height, so now I can grind the gel off of the surfaces we’ll be laminating, and I’ve also already started grinding the scarf joints on the inside.
My intent is to grind the external joints and tab the pod pieces where they lie currently with CSM, just to lock the location to each other. After curing, I’ll attach a 2x10 on edge externally right on the keel of the pod. This hopefully will keep the angular relationship of each piece, so when I remove it from the boat, flip it over and laminate the scarf joints, everything will stay reasonably in place. I fully expect some shrinkage, but am trying to minimize it.
Here’s the internal support bulkheads to keep the old pod walls from flexing and to add vertical support for the new pod. These will get filleted and laminated in. Because of the previously mentioned irregular surface, I made these about 4 times, because I would cut one either at a slightly wrong angle, or just a bit too short

Here’s a shot of the support for the rearmost piece. Because the Vee isn’t centered perfectly in the part and the angles are just slightly different, I probably made 3 of these.
Probably shouldn’t have a machinist mind for working on this stuff...

Here’s all of the pieces of the pod suspended and located where they’re supposed to be. Hopefully they stay exactly like this when I join them.

I have to say, I am pleased to finally get to this phase. My vision is becoming a reality.
Really nice work, lots of moving pieces but you got it and it looks great. I was thinking this would be a lot easier if you didn't have that pesky floor in the way, at least that way you wouldn't working blind.
Are you going to "bed" the pod in some goo where it contacts the foam and plywood bulkheads?
