in a universal confluence I found a bucket of pulleys in the metals area at work while thinking about custom moped chopper exhaust systems.
I used two pulleys as bending dies. The rest is scrap cutoffs, hence the ugly shapes. Let me stress this is only a test, so i will prolly make a better system, but I just wanted to (quickly) see if this would work.
The flat stock on the back of the assembly fits the groove of the metal table. The big flange is to clamp the bender to the table. There is also a flange welded perpedicularly to the end of the flat stock- it holds the tube while bending - I will measure this next time. NBD, but could be improved.
The pulleys are configured so that one is fixed to the table and the other orbits it. I used the rectangle tube to attach the pulleys because I could insert a lever/handle in it, and my only real work was drilling holes.
I drilled one hole, mounted a pulley, positioned a cuttoff of EMT, placed the other wheel, and marked the center of the axle, before drilling.
