Default And another ring roller

I did not want to steal Scratch's thread. Here are some pictures of the ring roller that I built some years ago. It will bend a 3/8 X 1 inch flat bar and maybe some more.
The first pic showes the chain drive, I was going to drive the gear box with a drill motor but to get the power out of the drill it would turned the rollers too fast and you would over run the bar ends and the end of the bar would drop between the rollers.
The second pic is a head on look at the rollers and the pressure bar. The bolts on top of the bar push down on the roller bearing block. Brass bushing are used as bearings for the rollers.
Pic 3 is pretty much the same as Pic 2.

Pic 4 shows the pressure bar at the top of the frame, the bolts push down on the bearing block. To remove the ring you pull the two pins( the bolt and the one with the cottor key) on both sides and lift out the top roller.

The ends of the ring do not form completely if the material is cut to the correct circumfrence. I either leave the material extra long than cut off after forming or I will cut to the correct length and weld the two ends togeather, grind the weld and put the ring back in the roller and reroll the ring. This way the ring comes out a true ring.
