I made a tool to straighten out coils of tubing. Makes it much easier to work with if it's straight and your bends will be more accurate. The tool works perfectly, tubing comes out arrow straight. Angle iron and patio door rollers.

Now that's cool. I don't know how many times I've had a coil of tubing I had to straighten. Can never get it good and straight by hand
