My basement shop is relatively small. I have tools and cabinets on the outside walls, and only enough room in the center for my cabinet saw with extension table and a my workbench which doubles as my TS outfeed. I've routed miter slots in the workbench to allow the miter gauge full travel. I've had the same setup at my last 2 shops and it's worked good.
The "problem" is that I finally am going to upgrade from a 2x4 and MDF workbench to a solid maple workbench with tail/front vises, and I don't really want to route miter slots in a nice solid top. My current plan is to have the new workbench/outfeed about 1/2" lower than the TS, and use a piece of 1/2" MDF when I'm using the saw.
The other thought I had was to place the workbench 6" or so away from the TS at the same height, and make a spacer that has the miter slots.
Any other thoughts or suggestions?
