Re: pic: Cheap 6WD
Another boat-builder trick for boring holes in wood: drill the hole oversized, and fill it with epoxy with some filler like wood flour (don't use microballoons -- they are too weak) or silica. You can put a 3"x3" patch of fiberglass cloth, not matt, on both sides if you want a little extra strength. Drill your hole right through the middle of the epoxy plug, and stick your fastener through with generous washers on both sides. This is generally done to avoid exposing end-grain to water in the hole, but it also produces a strong way to avoid crushing wood fibers.
I've had bad luck with CA as an adhesive on wood, but using it to saturate end-grain is an interesting idea. Thanks.
