Ya I agree, I'm actually considering making a rotary table for the grinders and drill press. I saw one on pintress that sits in a corner and you just rotate the whole table until you have the tool you want to use in front of you. I think that would be a better option than grinding dust right next to the fine equipment.I also wonder if the clearances around your Bridgeport are narrow. I don't know what you plan for the shelves and cabinets, but are they in an inconvenient location if you constantly have to get things from them or put things in them?
I cringe a bit seeing your sander and grinder where they can throw dust on your mill. I have that problem somewhat and it is a big PITA to have to keep covering things and cleaning as part of the workflow.
I should have plenty of walk around for the mill. I drew the bridgeport up to it's max travel so I can move the table one way or another if I need more room to get next to it. I can have close to 4 feet of wall to table clearance if needed, and 2.5 feet even if the table is fully extended one way or the other.
