[Rhodes22-list] Bow Chocks

[Graham Stewart]

There is no task relating to boats that is so simple that someone has not
figured how to turn it into a 400 step three-week process. Drilling a hole
into a cored deck is no exception. This information at this link
http://www.pbase.com/mainecruising/sealing_the_deck will explain the
ultimate process very nicely with a multitude of photos. A bit daunting but
well worth the read. It might be overkill for the chocks but still the point
about countersinking the gel coat is explained very well.

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.

Countersinking the screw holes is a great idea. Suggestion to  prevent
cracks
- start by running the drill bit backwards until you're  through the gel
coat, then use a larger drill or countersink in reverse to  finish the hole.

Rummy is probably right. There is no wood core in the edge that  can rot
anyway and the fibreglass is quite thick there. So that would not  be a
concern. If you decide to do that I would countersink slightly the  screw
holes in the gel coat and bed the chock carefully as you will  otherwise
probably get spider cracks in the gel coat around the screws over  time.
