Alright, well i guess an update is overdue...

I reinforced underneath the cap where i intend to bolt in the tower. I cut to fit a piece of wood, then epoxied & clamped it into position. Then I came back and smoothed the edges with fillets and glassed it in with 2 layers of 1702.

Here's a shot of the underside of the cap, with just the wood expoxied in, before fillets & glassing.


I didn't have the right clamping setup, so I had to improvise.
