[QUOTE=take a potter;270943]So just to go down this rabbit hole.
What would the layup schedule be if you were going to glass in a half of a 3" pipe?
FIRST - This is my FIRST project like this. Lots of guidance from folks here and elsewhere, but there ya go.
I cut a SIX inch drainage pipe in half. First, I ran 3 layers of 1708 down the keel after grinding out all of the old tabbing and cleaning up the glass there. I ran it wide enough to make sure the pipe and the fillet would fall inside of it and that the glass over there pipe when I glassed it in would make contact with it.
I scuffed the pipe, shaped it a little up front to get it to lay down nice and laid it on a bed of cab thickened epoxy along its edges. I then filleted the running edges with thickened cab.
I ran three layers of 1708 over the top of the pipe.
As to other keel support/transverse support etc, I'm sure others on here have more experience than I do.
I added bulkheads between the stringers and ran low transverse supports under my fuel tank beds that were filleted and tabbed in with 1700.
