[TheForge] Twister (Was:: housekeeping...)

[Larry Brown]

They make good twisters on cold stock. A guy I used to work for had a set 
up with one that would do up to 3/4" with a homemade gizmo that would shut 
it off at a certain time (Variable setting) Once you set it up you could do 
bar after bar with very little variation until you used steel that was from 
a softer or harder batch. He was a cut and paste shop, but cold twisting 
gives an even twist
Have fun with it anyway
