While I like it, I'm not sure what the cantilever platform off the bench face buys you?
Hauling it up and down every time you need it sure precludes any convenience. If on a hinged or pinned pivot, I can't seem to see it from my network's firewall.
If in need of space, you need to put that grinder on one of those articulating parrellel swing arms like the t.v's in the hospital rooms or those used in ICU rooms for monitors and equip.
Heavy duty and two arms mounted on 3 pivot points.
Or go moveable pedestal on the floor.
If your grinder is in the way of bench space, the bench surface behind it would become a tool "sh&t collector" sadly in my world.
Even swing down does not get the grinder out of the way in that pic. Grinder still in the way of getting to the bench.
Swing arm that pushes over in front of the double bank box, winnah!!!!!!
