If you are going to use the router to remove waste why not use a bigger diameter bit, clamp a back stop , and rout free hand? This way automatically provides a precision cut at the back of each socket plus a smooth accurate bottom at the correct depth. You are then left a small wedge in each corner to remove by chisel, having already established a clean reference .
Having a router with a circular base makes it simple to set the back stop at the correct distance which is a function of bit diameter plus base radius.
You have already defined the edge limit of each tail by hand sawing so guiding the router by hand only involves stopping before the bit cuts into the saw cut at each side of the socket, which is very easy as the saw cut is like a very thick pencil mark ie it is hard to overshoot.....
