what bender are you using locktup. I couldn't remember if I asked you or not.
http://www.toolsplus1.com/eztube.htm The only thing I don't like about it is it wont bend past 110 degree's. Other than stingers I haven't needed to bend more than 110. The bender kick butt.
I should get a bunch done on Sunday. Bob keeps adding to the list of things to do which is good.
