Grant, The finished die looks great but I can't figure out how the tools works from the other pic.
I know how the external radius tools work for making knobs etc so I guess its somewhat similar did you make it yourself ?

Colin,

You had asked how the tool worked.

The wheel at the top turns the shaft that holds the small carbide insert. The insert adjusts in and out which is what determines the radius of cut for the die. This cutter will ONLY cut a concave cut. I have another radius turning tool that will cut convex parts (balls). My other tool is slick as $hit and will also cut concave parts, but is limited to cutting into parts that are no larger than 3" OD. The cutter pictured above has no limitations to the size of stock as there are no parts in the way.

Clear as mud now! ;-)

Prolly cooling tubes. We do alot of these. The company I work for, all we do is roll bending. We have six machines and a 12' plate roller that does up to 4" thick matieral. I'll get some pics. The biggest beams we have done are w44" x 292lb. It was awesome. Ill take some pics and post them. The tighest I have gone on the plate roll is 23 3/4" O.D. on 1 1/2 thick plate 24" wide it was pretty cool. Ill take sme pics tom and get them up

I got tired of turning the crank, so I added POWER!
Found one of those cheap 120Volt winches, at a yard sale for 20 bucks, and added it to my HF Roller. Works like a champ.
I have rolled a bunch with it, and the only issue I have so far is some heat build up from the motor.
I just mounted the winch on a slide below the bender, and hooked it up with chain drive.
as the adjustment is turned down the motor lowers with the help of a small spring, and keeps the chain tight.

I drilled out the set screws and replaced them with pins, on the roller itself.
Anyway, it was cheap like me, and it works.

Fawsome!

Your top screw is going to strip out eventually. Mine and everyone I know with one has. We've all added some bracketry for hydraulic jacks on top to replace. We've also welded some square stock the length of the main slot up and down on both sides and added an additional bearing that rides between themt o keep the slot from wearing through the main drive shaft. Adding bracketry out the sides for additional wider bottom holes helps A TON! Finally, we've also broached our dies and replaced out drive shaft with a keyed shaft to eliminate the shitty set screw. Its stupid what all you can do with that cheap harbor freight bender to make it 20x better than the super-expensive ones.

I have been looking at the threads already. Kind of figured that was the next upgrade.

Half the fun is making this thing better.

IS the coil formed simply by offsetting one wheel or two or???? I know how the loop is formed of course.

Also whats everyones take on the bottom two rollers? Is it worth making them adjustable for width? Or jsut set them in one spot and drop the top wheel farther down?

To coil material, you need to adjust the latteral roller guides out. They are the 2 rollers that are slanted at a 45 dgree angle on each side.
