Talk about big big rollers
There is a Guy in America with a lot of time, scrap metal, and tins of paint on his hands that made a low budget big stone roller grain mill for crushing malt.
This is what this McGuyver came up with:
Start with a couple tins of paint as a mold and fill with concrete, using some metal pins for mounting the rollers later on in the frame. He said the most difficult part was making sure the holes were perfectly centred to get a good roll.

Mount into a frame with motor. Note: 63 rpm seemed too fast for these big rollers.

Steal SWMBOs high tech grain hopper, or in this case a Light Reflector housing.

And crush that malt.

Hats off for ingenuity, not sure If I'd buiild a stone grain mill myself unless I really was into the big rollers
Cheers,
Brewer Pete
EDIT: Fixed any problems?
Seems like stones would wear down over time, fix any issues with perfect centre alignment? There are two yellow plastic jigs on the bench in the second photo that are used to quickly set the roller gap. Probably could make a few sets up depending on the crush level you would want.
