Very nice. So you machine the contact wheels out of al bar stock to the radius you need for a specific miter, correct?

"I needed one of these for cutting some thin tubes..."

Do you need this because a regular cutter distorts thin tubing?

Off subject here, but in the flicker pictures just before the grinder the red/maroon bike is a gorgeous color. Is that a clear powder coat with a tint that allows the heat coloration of the tubing to be seen? Very, very nice effect!

thanks, Brian
