I decided to make my frame a little more mobile, so I cut some angle, put some cheap harbor freight casters on the bottom and welded posts to the frame. I can fine tune the level when needed and roll it in, out and around the garage which is *very, very important* since Mama still needs to park in there.
Spent about 2 hours knocking out rivets and removing un-necessary crap. Still have a bunch to go, those rusty rivets are a pain. My method is to cut an X in the head with a grinder/cut-off wheel then knock the heads off with an air hammer and punch them out. Works like a charm!
