Double wheel hollow grinder

John Greco built a set-up (possibly two) like that back in the 80's-90's. He allowed me to take some pics of them when I toured his Mississippi shop way back when.

Every time you change grit sizes, the effective distance between belts changes.

How are you adjusting the contact wheel spacing ?

One of the uprights is fixed the other pivots at the bottom. There is a piece all thread that pulls the uprights together and a strong spring that pushes them apart. I turn the adjuster on the all thread to move the wheel on the right.
