I am designing a multipurpose work table for the shop. The table will be 4’x8’ and will be an assembly, cross and rip cut surface for sheet goods, router table, and storage. I plan on putting the router on one of the 4’ ends. Since I am not constrained to a certain amount of space such as my old setup in the wing of a Tablesaw, I am undecided on how far to put the router from the edge of the table. If you had a blank canvas, how far would you have the bit of the router from the edge of the table?
