You can get 50mm wide woven tape which is good for this sort of job. When that has gone off seal that with gel coat.
How easily did the glass come off the ply core when you cut the hole?
It may be delaminating if it fell off easily.
Was the ply wet? That might explain why the cutter was binding.
I hate those multi-size hole cutters. I am impressed you got anywhere with that one.
Cheers mark, that sounds like a good idea
- if its any consilation with a boat as small as mine its a pig of a job as theres no room, I sweating like a pig inhaling burning wood/fibreglass fumes,deafened by drilling and fastly catching the tourettes syndrome -
the glass needed a bit of poking, ply was thick, bone dry, and made of many intact layers
thanks all for your replies
