I've had this idea to use a power steering box/pump to drive a tubing bender for quite some time.Recently a member on OFN,Vern Lee was ballsy enough to give it a try.So far it seems like he is very happy with it and I thank him again for testing my idea.(even though I knew it would work.)Most of this idea was discussed on another board,here is a link that thread.

It was also requestd that I post the pics here so that members here dont have to join another board.Some of these pics were already posted somewhere here but I dont remember where.Some of these pics are of Verns bender,hopefully he doesnt have a problem with me posting them here.If he does ,I will remove them.One of the sketches is a little hard to see but its a scan so nothing I can do about it.

Heres the link to OFN also,basically the same as here but Vern is a member there so he can answer any questions I cant.

I know speechless right?

Speechless? No, links are no good.

Woops,my bad ,I'll fix it.
Fixed and added another link.
Sorry Fabr.

Cool!

IF it will bend as fast as you can spin the handle, then I would think you could either change the pulley ratios or go with a smaller displacement pump. Doing so might cost you a little speed, but would allow for a smaller motor running off 110 instead of the 220 one he had to fit.
I would also think the running the dies on a well supported shaft and driving the end of that shaft would be a stronger design than running the dies right on the steering box output shaft.
The big question though, is will a pick up steering box have enough power? Or is a big truck box a necessity.

"The big question though, is will a pick up steering box have enough power?"
You nailed it! I'm going to say yes.I'll find out soon,I'm planing on finally doing some mock-up tests.
I'm sticking with the die on the shaft,I dont want any extra moving parts.
