Found this old 3" Barrett grinder in my late gramp's garage. I think it was a tool post grinder, or at least was used as one, considering the various mounting plates he'd welded up. One mount it didn't have was something just to set it on a workbench for light duty use.

This is that mount.

Here's the onshape doc: https://cad.onshape.com/documents/afcc45b71cf8658a13c2705f/w/80d1ca8e987cca5c85628979/e/7c4eed724aa6c6e7bc5b2b18

The machine tag on the grinder reads:

If there's another one of these out there, may you find this of use.
