Re: 1st big project, bronze thru-hull

I have Sikaflex 291 to use to seal the machine screws. I guess I didn't mean glass over the heads, I just meant to put some thickened epoxy over them. You're saying that's not necessary?

The existing fitting is on the keel slot, so it's on a sharply curved surfaced. I plan on putting the new thru-hull off to the side of that, on a flat part of the hull.

My plan is to cut off the "horn" and fill the hole with a thickened epoxy plug, then fiberglass over that plug on both sides.

I've never used epoxy or fiberglass before, so this weekend I'm going to play around a bit on some scrap wood to get the feeling for the stuff.
