derailer,as chain tensioneer?

[jackofalltrades]

I used an old Schwinn derailleur and mounted it with a muffler clamp. It worked very well. I also used a skateboard wheel that I made a groove in with a drill and file...chucked the wheel into a drill press and used a file to "route" the groove...as a chain guide and mounted this with a muffler clamp also. The muffler clamp "legs are long enough to extend into the chain path there by making them very useful for improvised guides, tensioners etc. This was on a homebuilt recumbent a few years ago.
