OK, I have an "Aw S*%t!" moment. I have a hard point with a bolt hole drilled out of alignment and I am trying to fix it rather scrap the part. The part is big and very time consuming to build... Don't even ask how I got the hole out of position - I am just crushed that I could make such a huge error.
The hard point has a laminated plywood core, a light fiberglass layup on one side, a heavy one on the other side, and an aluminum plate bonded and bolted on each side. Then the whole assembly was drilled and a bushing was bonded in too. The aluminum plates provide support for the bushing, so I do not think that I can just fill the hole and re-drill.
I know that we can not really bond aluminum to anything long term, so I am hoping that someone has had experience in how to help the aluminum let go of the epoxy so that I can remove these parts from the wood/fiberglass. If I can remove the plates, I can fill the hole with a thick mix of epoxy and glass, mount new plates, and drill in the right place. Any ideas?
The alternative is to fill the hole with a high density filler and drill for a larger bolt bushing with the hole drilled eccentric.
