Mandrel tubing bender-can it be home built?

the sketch in your link is very similar to the one I was thinking of

but the one I saw, and it may have used this diagram

showed in pictures the total construction of the bender, from turning the egg on a lathe to making bends..

great link though, I have it saved this time
thanks!

 

This bender requires NO 180* (half round) tubing support from the die or the follower, yet it gives perfect distortion free bends?

Man...thats just TOO frickin' EASY to build to work that good!!!

Wouldn't be hard to make that thing hydraulic either...

 

Anybody else have ideas on this old thread? I found a pretty good one here... http://www.offroadfabnet.com/forums/showthread.php?t=1661

 

I can tell you with absolute certainty that design is a BITCH to bend 120 wall DOM by hand, as in, it won't do it. Gotta go hydraulic or thinnner wall. Needless to say, mine is still in process.
