Flat bar ring roller

[Charlie C]

Hi all,
A few days ago I asked about a rebar ring roller, it seems that there is not too many plans for a machine to roll rebar rings. So I guess I will make a machine based on the machine it the pictures for rolling rebar rings.

I built the machine to roll flat bar and now I would like to have a machine that would roll round/rebar.

The machine in the pic will bend a 1-1/4x3/8 flat bar into a 12 inch ring or smaller.

Instead of having the rollers in the center I am going to put them on the out side, this way the machine can be made narrower.

What do you think?

Keep us posted with photos on your new design. How does the center roller adjust? From the photos the center shaft bearing can not be raised due to the knotch in the side rails. What am I missing.

Just have someone cut a couple grooves the radius you need in your rollers for round stock, and you can still use it for flatbar. Mine has 2 round grooves and a square one for sq tube...Bob

Looks like the bearing blocks are slotted to ride up and down the slots in the side plates. Should work well.

Nice project.

Sorry I have not answered your question Jim. WB5 is correct the bearing blocks do slide up and down in the slots. The bolt through the the bar is what puts pressure on the blocks.
