Didnt see many of these while doing a search so I thought I would post this up. Made it a few months back.
I built this off & on over the course of a couple months. It`s not quite complete, but, it is useable.
After using it, a couple of my suspicions were confirmed:
1) I need to probably double the size of the handle.
2) I need to knurl the two bottom rollers slightly, to help when rolling flat stock 1/4 inch and thicker. I will also be machining guide grooves in the upper roller to aide in rolling solid round stock 1/2 inch and thicker.
Eventually,I would like to make an upper roller for doing 1" or 1 1/2" square tubing, as well as comparable size angle.
The specs. are:
The side plates are 8"x8"x1" thick.
The bottom plate is 6"x8"x1" thick.
The shafts are 1 3/16" dia. by 7" long.
The rollers are 2 3/4" dia. by 3" long.(will be changing the bottom rollers to 5" long. I will also be changing the upper roller to 3" dia.(to enable me to make smaller dia. rings.)
These are the first practice pieces:
1) complete ring, 1/8"x1 1/4" cold rolled approx. 10"
2) small incomplete ring 1/8"x1 1/4" cold rolled approx. 5"
3) "U" shaped piece 1/4"x3" hot rolled approx. 30" in length( this is the one that changed my mind on how big the handle needs to be)
