[Rhodes22-list] Bow Chocks

[Dennis]

Hi Rummy - 

The countersink is for the bedding compound, not the screw head. It allows
minor (thermal) movement of the boat, screw, and hardware without stressing
the bedding compound or the fiberglass where the screw leaves the hardware
and enters the fiberglass.

Countersink what screw holes? The screws you use will be determined by the
hardware you choose. It would be nice if the chocks had a countersunk hole
in  them to hide the screw head, but you can't hide the head in the fibe
rglass since  the chock is sitting on top of it. Drill a small pilot hole
through the gel coat  and glass. Then drill a larger hole at slow speed so
you won't heat up the gel  coat and cause it to crack. I've known some
people that like to put masking tape  where they are going to drill. It
never helped me. 
Fill the holes with a  good bedding compound and install the chock and
screws. Ta Dah! It's not rocket  science, just good craftsmanship.
