Making a Jig To Bend Circles etc.

Making a Jig To Bend Circles etc.

I need to bend a perfect circle out of 10-20 mm rebar. I am currently trying to bend around a strong pipe welded to a piece of angle holding it in the vice.
This takes me too much time and is too difficult and takes the enjoyment out of the craft. Cannot afford to buy a tool for this and the tools they do sell are not strong enough for bending 20mm rebar. If anyone could help me out, would be well appreciated.
p.s. image is a small one to bend 12mm rebar cold. Have not yet built one for 20mm rebar. Seeking advice first.

Rolling rerod

There is a shop built rolling machine that I like the looks of. A set of pictures is shown at the Metalworking Dropbox. Just scroll down to the Roller.txt file and also see the pictures that also start with the word Roller.

Rick, thanks a lot for that link. That looks like a brilliant jig. That baby would be perfect for what I need.

Cheers Greg

Tell me about it Greg, I work as a Shuttering Carpenter, sometimes do a little Steelfixing also. I have only worked with a little on site bending jig that could only do a few angles. I can only imagine the types of machinery you get in a rebar shop. Would love to see some of the machines and work you have done. Cheers
