Some progress…
The foam mold was partially destroyed, but it came out in one piece. If you don’t have enough mold release (wax) it will take more work or be impossible. This one pretty much popped right out (10* relief helped here as well)
Material removal was done with a grider and a cut off wheel, then 60 grit flap disc. Be kind to yoursef and do this part outside with proper safety gear👍
I went right to the edge of the deck, the lip that’s going to take the bolts looks a little skinny in some places, but I’m confident I can squeeze the bolts in. 12s5p here we come!
