It's ok, I know my way around a garage pretty well. I pre-drilled with a 1/8" bit first (went thru 4 drill bits) but I got them drilled and tapped. I only went about 5/8 deep, but I dry fit the pipes on, all bolts (i'm going with stainless Socket Head Cap Screws instead of studs) threaded in well, so I think I'm good to go (knock on wood). Took the pipes back off, got a good coat of 2000 deg paint on them, and now I just have to wait until I get this industrial rust stain remover in the mail so I can get this thing cleaned up. Mount the pipes...and I'm all done. Part of me is saying "who cares if all the aluminum is red, just put it back together already"...but that ain't me. I want it to be purtty in there. In the end I'll have about $400 and lots of labor, so if it keeps running well I'd still say I got a pretty good deal.
