Has anyone used one of these to bend pipe for exhaust? If so, how'd it do?

Nevermind, I searched this issue. My bad. You can delete please.

I tried to use that exact bender to bend 1/8 thick 1.5" tubing to build a roll cage. All it did was make 3 dents in the pipe. I even tried filling the damn thing with sand and it did the same thing.

 

After I got rid of it a friend told me that he used the same bender on a rollcage (same material) but had excellent results. He said that had to alter the die to make it bend without creasing. He also said that a couple sheet aluminum shims on the sides of the pipe helped a lot also.

I bought one of those a couple weeks ago. Haven't even opened the box yet. Plan on using it to bend pipe for a frame on a custom Subie Trike.

 

Iwill keep your tips in mind BoostedBalls when I get around to actually doing some thing with those plans. May consider a bit of heat as well!

Thanks, Stumpy
