....I have decided to go one step further with this repair.

Since the thick steel bar at the bottom has two, large bolts reaching up into the hollow cavity, I thought I would further stabilize the structure by mixing and pouring a high-strength, shock-resistant epoxy into the interior of the cavity after sealing off all possible openings through which it might otherwise leak out. I have selected 3M 2216 epoxy since I have a lot of experience with it. It is not my expectation that the epoxy will actually, strongly adhere to all the interior surfaces. What it will do though, is surround the large studs and fill the space between them and all of the intact sheet metal, and repaired sheet metal that I installed last week. I think that filling the cavity with the epoxy will add enough additional strength that the repair will last a lot longer than it would otherwise. One problem with this approach is that 2216 costs about $150 per quart. So it is not cheap.

Cheers to all DIY'ers.

So how did this work out for you?

I'm thinking that mixing glass fibers into the epoxy would give it even more strength.

I love seeing old threads come back from a long sleep, some topics are truly timeless and it would be good to know how the ideas discussed tested out over the long haul :hmm
