Hi all,
I fiited a new log to my boat, and the diameter of the new skin fitting is slightly less than the old. So the original hole is to to large leaving a 5mm gap all the way round the fitting.
The flange on the outside of the fitting is wide enough to cover this gap, but I'd prefer it to be a nice snug fit, so my plan is to fill the whole and then redrill with a correctly size hole cutter.
I used a file to bevel the edge of the hole to roughly 60 degrees and plan to fill it with SP Epoxy thickened with microfibres. Most of this will go to waste when I redrill, but never mind.
Any comments on the suitablitly of this technique and materials are most welcome.
But my question is, should I used slow hardening epoxy, or will the fast stuff be OK. I have fast on the boat, but will have to buy slow hardener especially for the job. The hull is about 10-15mm thick, so I'll be applying epoxy to that depth.
I'm guessing that the fast epoxy may generate heat while curing and get too hot, which can affect its stength. Is this correct and will it be a problem for the job I'm describing? I can build up the filler in layers if necessary, if so how what length of time should I leave between applying each layer and what would be a sensible thickness. Say 3 x 5mm layers with 2-hours between each, for example.
Or am I being to much of a worrier. It's only a little job. Can I just slap the stuff on?
Comments and advice much appreciated.
Thanks,
Mark.
