I am making some drawers from 1/2" baltic birch plywood. I am doing half blind dovetails. In setting up the jig, the last step is to set the fence the proper distance from the edge of the router base so that you plow the proper depth slots for the pins. In the case of my particular router, that distance would be 3 5/8". However, the slots were too deep and I ended up backing off 3/32" to get the pins at a perfect depth in the slots. Obviously this isn't a crisis as the end product looks great but I am really puzzled about why the fence distance was off. I checked all my measurements many times in computing the 3 5/8" so it is making me a little crazy. If anyone can shed any light on this, it would ease my mind even though the end result of my project looks fine anyway.
TIA.
