what mollers said works good .....also i have found drilling a small pilot hole then use a wide head countersink bit first before drilling the final hole size.

another one i use is a lathe centre drill ....this gives you a small pilot hole and 60 degree countersink all in one.
I have also found a slightly blunt drill is better.. a nice new hss drill bit will grab and crack/tear surrounding gelcoat ....


regards

Ian

Yeah, I wondered whether that would be a good way to go. Never had an issue with munched holes myself. When the screw, bolt/washer or fitting etc is fitted the hole is covered.

There are some drills on the market which are more like a trepanning tool. They have two teeth on the OD which scores the OD of the hole. These are brilliant, if used slowly and carefully.

I think the biggest problem is being impatient. Does it really mtter if it takes three minutes to drill a hole rather than fifteen seconds.

The drills mentioned above are also neat on the inside since the OD breaks through first.

i think weve all done that at some point .......for me the best by far was the countersink .......on another note ....when i removed my console i found myself with a 1/2 thick layer of fibreglass the full size of my console needing removed ....rather than grinding i opted for a heavy duty electric planer ...with dull blades .....brilliant at removing fibreglass and leaves a reasonably flat surface only needing minor surgery after (topcoat).
