I have realized that my router insert I made for my table saw could benefit from having a miter slot closer to it, so I decided just to route one into it.
It seemed logical to reinforce the area underneath the slot, since I was taking away half of the 3/4” of plywood and creating a fault line in a piece that supports a motor spinning carbide bits and thousands of rpms seemed less than optimal.
The only drawback is that I don’t have T-slot doing it this way. I don’t see that being a huge drawback at this stage in the game.
