It is my variation on the Hugh McDonald Rolling Mill. I didn't bother with the cam mechanism at the bottom of the over-center lever, as it strikes me as unecessary. Rather than putting the lower die on a swing arm, I made a carriage that is constrained by means of two 1/2" shoulder bolts on either side; this arrangement allows for the dies to ...

You wouldn't believe how fast power requirements scale up with roll size! For instance, a flat rolling mill with 36" diameter rolls may need 15,000 HP at 60RPM. (And still stall.) Now, one other thing. If you are using a McDonald-type roll gap adjustment with the foot pedal, that's all the protection your mill needs.

2 rollers, the top keeps rolling and the bottom gets squeezed by lever action with the step of a foot. Yep. That's about it. The top roller goes real slow, something like 20 rpm. You can't really take big bites on the steel, meaning you are not going to turn a 1" x 6"" square stock into 1/4" very fast.

760. Jul 8, 2002. #2. I just completed my rolling mill about 2 weeks ago. It has 8 1/4" diameter rollers and turns at about 35 to 45 rpm. It does a fantastic job of rolling damascus. I completed my MS test knife using 52100 and 15N20. The only thing that I see is that if you want a pattern, you have to put it in.
