    Bender roller combo

    A while back someone posted a unique form of metal bender with rollers for rolling and a die for bending
    I think it was called the ultimate bender or somethin like that
    I liked it well enough to decide to build my own version with a few upgrades

    I put a large bearing where the cams action slide pivots

    just need to insert a bar in the hole to turn the shsaft

    the rollers are cam followers the apex roller has a pipe sleeve pressed over the cam roller with a handle welded to the pipe

    I used 1 bearing cup and 1 end of a u joint cross to be the eccentric drive cam

    All plate parts are from 3/8 ASTM 514 (T1) steel 110,000 PSI tensile WHY? because I have it and I can.

    It works great for the thicker materials 1/4 to 3/8" but for narrow and thin like 1/8 by half the material is too soft for the spacing of my rollers and the apex roller cannot get enough friction to pull the material through.
    I plan on adding pipes and sprockets on the idler rollers then drive them with a chain later on .
    Also I have not added the holes to attach a bending die at this time since I haven't need that yet.
    I made this a couple months ago and yesterday was the first time I needed it
    If someone finds the thread of the other bender please link it to this thread as I would like to give him credit for the idea

    Re visiting this thread as per a request of more information from a member.
    he was wondering what the large bearing under the slide was for.
    I made it with the intention of eventually maybe adding angle iron pieces over the rollers to make sharper more defined bends though never got around to doing so I tried using it to make letters for another project out of light gage 1/2" sq tubing but ultimately used another means to form them.
    By inserting a bar in the shaft that extends below the bottom of the machine and rotating it 90° to the left or right the top movable roller functions as that of punch in a press the 2 stationary rollers serve as the die
