a really light weight canoe. A couple of layers of Kevler and
an layer of glass and then stiffen it up with Kevler or Carbon
over a little foam corrigation.
I would use the canoe as a male plug.

I vote for vacuum bagging where possible also. I don't know what
visqueen is, but you can make a serviceable bag with heavy
polyethylene and automotive strip caulk. Paper towels will work for
bleeder material, tho you might need something more. Try web surfing,
I think a lot of the model airplane guys have articles on this. Not
sure about leaving a shop vac on 24 hrs tho (necessary with slow
epoxy).
As far as screws go, I like the self drilling screws that have
something like a mini drill bit on the end. They cause less splitting.

The best way to hold large sheets together is vacuum bagging, which is
really a lot easier than it might seem. Just envelope the sheets in a
visqueen bag and suck the air out with a shop vac. Works great. Gives a
lot more pressure evenly distributed than mechanical fasteners. The
Gougeons have a good pamphlet on it and you can find out more doing a search
on "vacuum bagging"
It's fun too.

Drywall screws are much better - just be careful not to strip them out as
you tighten them. Back 'em out and patch the holes after your glue is set.
