You should
modify the tubing bender. This one is made by General Tools, and came from
Avery. Rigid
also makes a good one of similar design, found at Home Depot. On the
RT end of the grooves in this picture (upper arrow) is where the moving arm comes down
over the curved portion of the tubing bender. This was a rather abrupt
edge, and it was denting the tubing sometimes, when I swung the arm over the
tubing to begin the bending. I beveled the edge with a round file,
then polished the whole edge, including the groove, on my fine scotchbrite
wheel. It seemed to make a big difference in the quality of my
bends. A drop of oil in the groove on this arm
will also help make the bends nice and smooth, and free of nicks and dents.
Also radius and
polish the fixed arm where the lower arrow is. This, too, can dent your
tubing with an out-of-the-box tool.
The edges
shown here also need to be radiused and polished, too, or you can get denting and
scratching.
