I’m a pro at resurrecting dead threads. Anyway, here’s my problem, I broke a bunch of the 3/8” stainless beam bolts in my N20 taking the boat apart and now I’m screwed (no pun intended).

Attempt 1) Used a fairly small diameter titanium drill bit to drill into the first broken beam bolt. I was making good progress but then the drill bit broke. Then I proceeded to use larger diameter drill bits to continue to drill into the bolt, but the broken titanium drill bit dulled the new drill bits. I suppose if I just keep going through drill bits, I’ll get to the end eventually. Any thoughts on this problem?

Attempt 2) For the second broken beam bolt, I switched out titanium drill bits for carbide drill bits with hope that if I break another drill bit, it’ll be easier to drill through a carbide drill bit. Ended up drilling through the bolt, but realized I wasn’t even close to center on the bottom of the bolt. Now, I don’t want to keep going up in size because I’ll chew into the fiberglass. Maybe I can use a small diamond tip dremel and wear away at the sides of the bolt?

Besides the two beam bolts that I’ve already f’d up, I have two more to go. I’m thinking with the next two, I’ll use this product… http://www.quikcenter.com/ Thoughts?

If worse comes to worse, my plan would be to cut out the broken beam bolts from the hull and 5200 new inserts into the hull, but that seems sketchy.
