We bought it back in 2006 and found then that we couldn't accurately bend it in a way that suited our needs.
I'll PM you a screenshot of our claw so you can get a better idea of what we're going for. |
Our team built its own pipe bender to bend 3/4" 1/16" wall tubing. It took about three days to build and was fairly cheap (considering it was built from scrap). We were able to bend a 27" diameter ring with no kinking or deformation.
If you are interested, PM me and I'll explain how it was done.
Before we did it ourselves, we recieved an estimate from a pipe bending company that wanted to charge us $2000 (including discount
) with a lead time of 20 days!
