I redid my lathe area the other day. I had a bed extension on the lathe and used the extra capacity maybe twice in the last couple of years. I had the grinder across the shop on another cabinet. I took the extension off and brought the grinder to the lathe bench. I built the back so I could put the light over the lathe. It's against the garage door and I didn't have any place for a light and it's kind of dark in this area.
It also allowed me to move my workbench to the place where the lathe was against a wall. This will let me build a wall hanging tool cabinet for my hand tools over the bench and get them all in one location. I will also get better natural light at the bench now.
It is the garage and on occasion I put a vehicle inside to work on when it's cold or hot outside and this arrangement let's me do that much easier.
