Default Re: Exhaust tube bending

I played around with some 3/4 conduit tubing to make a cargo rack. Using the sand filing method I got some crimping on about a 1.5 inch radius bend but not too bad. I really think could have tamped better though.

I tried the same bend with a dowel inside the tube and the tube crimped MUCH more severely. Sand filling is clearly superior.
