  • Rebar ring roller.

    Hi fellows.
    I completed my rebar ring roller today and thought that maybe of some interest.
    This will be mainly use to roll rebar into rings to make flower pot holders and any other required rings.
    The rollers that are shown is for 3/8 rebar. To roll other diameter material I will make wheels for that diameter.
    The pressure wheel swings from a 1/2 bar located here at the top corner of the side plates.

    Testing the machine today I was able to roll a 4.5 diameter ring.
    The brass block is the anchor point for the pressure screw.

    The chain is #35 and drives both of the lower axels. The angle drive gear box gives me more controll with less effort turning the rollers but takes more time.

    The pressure screw nut is located behind the top spacer bar, that is the bar that is across the top corner of the side plates. That corner of the side plate may get cut off at some point in the future. At pesent you reach the pressure screw by reaching under the spacer.

    The last picture is the first ring that I rolled. It is an almost perfect 12 inches in dia. At the top left of the side plate is the pivot point for the pressure wheel. That pivot point was used to O/X tourch the arc that the pressure wheel swings through.

    Sorry about the quality of the photo, I was shaking to much and should have used the flash.

    Very cool! Thanks for posting - a ring roller is another one of those projects i've had in my mind for a while but haven't had either time or resources to get around to it. I think your post has illuminated some hazy areas in my mental picture of a ring roller.

    btw - nice job cutting the arc that the wheel moves through...that must be what, inch plate? I've torched the stuff before, but it always comes out lumpy and messy looking

      Nice! Are you going to go all out and put a motor on it?
      I just need one more tool,just one!

        Looks nice... what's the reduction in the gearing.
        Wow... where did the time go. I could of swore I was only out there for an hour.

          what's the reduction in the gearing
          The reduction is 30:1 depending on the size of the ring ,it does take a lot of turns to roll a ring.

          Are you going to go all out and put a motor on it?
          If I should happen to find the right motor, I might or how tired I get from cranking on it.

          The side plates are 3/4 inch plate.

              Very nice and HD Charlie, I like that

              What is the purpose for the arc over a straight vertical adjustment.

              Thanks

                Very cool man, this is one of those projects that I've been wanting to do for a while, good to see someone else has made one also. It actually looks very similar to what I planned on doing. I guess there isn't too much variation on making one of these!

                See, I figure, if I have a machine that can bend roundbar, I can be the next OCC j/k

                  What's the procedure for rolling a ring to a specific diameter? Do you cut the piece a little longer than needed, then chop off the small straight ends before welding? Or do you weld the straight ends together, and then roll it some more to get that part round?

                    HI
                    i'm not awake yet so i probably don't see it, but i'll ask a dumb question anyway.
                    when you get around to changing the roller (die) diameters do you have to change the chain length? or is it built into the arced adjustmentment slot you torched and i don't see it.
                    very nice by the way.
