Rolling Mill

[Ralphxyz]

That's funny I knew there might be a conflict with using that term "Rolling Mill".

The screw jacks work well, there are things to watch out for, like the need for the vertical stiffeners.
If you jack one side higher than the other it is surprising how much more torque is needed to to raise the jack further, you understand real fast that you are dealing with considerable weight.

The channel iron is 4" x 12" x 3/8", 18"+ would be more stable, and with 6" channel you could get full swivel with the swiveling castor.
Again one only needs 1/4" ground clearance but it can go higher, with caution when moving. If really jacked up I would only roll front to back and
not try to make any turns.

At 1/4" you can spin it around.

I started think about doing this a year and a half ago, finally got to put it together.
It was fun I got to use my Harbor freight Inverter welder, which was perfect for this job, I got it on sale for $99.99.

I also learned the usage of a boring bar, that was something I had not yet gotten to so that was fun.
I only ruined two carbide boring bars. Finally got the feel for it, I will be doing a lot more boring I am sure.
