well I had an idea for a really bad ass tubing notcher, like the ones sold by mittler bro. I would get an old motor, slide tables, and a milling vice, and rig up a table to hold it all together. I was also thinking I could get some sort of motor speed control. The hardest part for me to figure out thus far is how to mount the cutters. I have lots of r8 collets and cutting heads, but i need a quil and some bearing for it to ride in, or something like that. any ideas?
