    I found plans for the JD-Squared Model 3 manual bender on a Chopper site free-of-charge after some searching. It wouldn't be very hard at all to reverse engineer from a pic anyways.

    Here's the Pro/E model of the model 3 bender -- to the print but with a custom die.


    Here are all the materials required: 2" strap, 9" round T6061 bar, some .120 DOM, and some hardware. Off camera is an old sturdy dumb-bell rack which will become the stand for the bender. Total material cost for bender and two die sets is around $250, all off feeBay except the hardware & pins.



    And here is one of the radius cutters we made out of A2 tool steel. Will gouge out most of the meat with a regular cutter, and then make a few passes with the full radii cutter.



    Drive pin holes and all strap piece holes will get drilled on my drill press with XY table. Nice thing about this design is that most of the dimensions have a nice fudge factor. The alignment / spacing of the die to the follow-bar is really the only really important one. The matching strap pieces will get drilled in pairs to ensure a match.

    Some might question my choice for T6061 dies regarding durability, etc. But I'm only planning on bending nothing bigger than 1-1/2" .095 tubing, mostly ERW. Keeping the mechanism and pipe lubed during bends will lengthen their life, too. My immediate use for the die will be to bend some parts for my FL350's (i.e. tree bars, bumpers, etc).

    Not 100% sure on the "clamp" design (holds the end of the tube). The JD design requires more machining, and I can't use their "stub" design to hold the clamp since I'm using T6061, not steel. So I need to leave the die completely round for strength. Also been toying with a design that just uses tube clamp vice grips.

    Stay tuned...

    Learned a lesson when I tried to drill a couple 7/8" holes in my mild steel straps -- DON'T USE CHINESE DRILL BITS! Go to the tool shop and spend the $20-$30 each for good quality bits. Then make sure you've got the right RPM for the drill. Good tools used correctly -- makes a world of difference!!!

    And here is the making of the 1.25" die, 4.5" CLR...

    1. Holes, facing, and OD sizing on the CNC mill
    2. Lathe turning the radius with a homemade cutter

    Now I understand and respect why these dies cost what they cost from the manufacturers. It takes equipment and work -- neither cheap.

    Very nice!!!!!! now you know why custom stuff costs so much. Alot of time and money go ito making things. Big companies stamp them out by the hundreds. Some things are better built at home and others just not cost efffective. Great job with machining.

    Not really any updates on this bender. Spring sprung me all kinds of home projects, plus I bought another Quadzilla project to rebuild. Buggies are on the backburner for April.

    I just need to get the follower block made for this die and try it out. Need time...

    Woo-hoo! Bends like a charm!

    Shown is a piece of 1.25 x .120 DOM. No tool marks, no die marks, no deformation anywhere. Tube bend is .04" out-of-round (flat), but it's well within my tolerance. Anxious to get some .083 thk tube on there to make sure the thinner stuff bends fine, too. Very happy how this turned out!!!!

    Here's my cost breakdown:

    Cost breakdown:
    Plans - FREE (internet)
    Stand - $10 (garage sale pick)
    Aluminum - $40 (eBay @ Detroit)
    Steel bar - $60 (eBay @ Detroit)
    Hardware - $25 (Home Depot)
    Pins - FREE (had them)
    A/H cylinder - $96 (HF, incl shipping)
    1.25" ID x .50" washers - $4 (eBay, used for rear shoe and for front catch)
    Weld & machine work - FREE, except for the case-o-Bud-Select for the mill work
    SWAG mount - $100 (swagofforad.com, incl shipping)
    Grand Total: $335

    Not bad considering these things retail over $1200!!
