This shows that the grinders flip, and the closeup shows the locking pin & retaining bolt, which can also be used to attach a water tray. The recessed wheels in the base allow the whole contraption to be moved relatively easily, considering its weight & bulk. I hooked up a ~60' cord (just because I had it) to the outlet box on the stand so it can be used anywhere, but I may swap to a shorter cord once I build a shop.
