Thanks guys! I promise more pictures soon.. got all the rivets back in it tonight, and got one of the spindles all lubed up and stuck in place. Seems like small progress, but anything moving forward is good!
Found out last night that air compressors require occasional maintenance. It was running then made a very, very loud noise as the pressure release valve popped open. Then of course it lost all it's pressure and started to run again.. was loud enough to make me jump. I pulled the plug on it...
Tonight I actually read all the warning stickers all over the thing, drained (first time in 3 years?) it - cleaned the air filter, checked the lines... plugged it back in and it seemed to work..but I only let it run about to about 100lbs, then shut off while I used it for a bit, plugged it back in.. so on, and so forth.
It got me through all the rivets, so I'm happy.
