Can I still call this a work 'stand' if it doesn't actually stand on the ground...? Lately I've been needing to adjust both my front and read derailleurs, and have been trying to figure out how to jury-rig a work stand without shelling out a couple of hundred bucks for a half-decent one. I read a few ideas online this morning, one of which mentioned that 3/4" black steel plumbing pipe is actually the exact same diameter as a seat post. Bingo! What I did was attach a 1" pipe flange to the main beam that runs through the garage, and I threaded a 30" x 1" pipe into it. At the end of this pipe is a 1" to 3/4" reducer coupling and then a 6" length of 3/4" pipe which I slide into the frame and clamp using the seatpost. It's very rigid and sturdy, and when I'm done working on the bike I can just unscrew the whole thing from the pipe flange and put it on a shelf!
