Thanks Jole, The shoe is 1/4 of an inch thick, I used 1 1/4 phillips tapered stainless screws and pre drilled all holes first, Then I tapered the UHMW so the screw were flush and would't get caught on any thing, then I mixed some epoxy up and brushed it on the keel and layed down the shoe and screwed it down to seal it so far no problems.
