I need to bend some 1" tubing to 90 deg, would it work if I packed the tube
with ball bearings and bent with a press? I tried packing with sand but it
didn't work too well.

You know what I do when I need a neat tight-radius bend in pipe or tube?
I buy the elbow from Wagner and weld it on and sand off the welds. With
care you can barely see it was welded, and their bazillion-dollar bender
makes bends PERFECTLY.

On thin wall tubing, you might be able to use a heavy duty spring.

^^^^^^^^^^^^^^^^^
If you try it, please send me a picture of the result. I visualize
something like a cucumber. :-)

Are you supporting the sidewalls? I've seen homemade benders made up
out of stacked disks of plywood with grooves for the tubing. No idea
how well they work, but it seems to me that supporting both the inside
and the outside might work better than just one or the other...?

Ideas to play with, anyway...
