Tubing Roller math and physics
I can't get my head around this one.
I intend to build a tubing roller (different than a tubing bender).
I'm having trouble with the math/physics of the roller placement.
What does the distance between the two bottom rollers affect?
I [I]think[/I] it affects the minimum possible diameter of the arc/circle.
The closer the bottom two rollers are to each other, the smaller the potential radius of the arc/circle.
But the maximum potential radius is not affected by the distance between the two bottom rollers.
The distanced between the two bottom rollers will also determine the maximum size of the tubing that can be rolled.
And I [I]think[/I], for the same distance between bottom rollers,
using a larger tube will result in a smaller radius.
Right?
