    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
