Thanks for the feeback. I guess because I have never used a router before, and my jig was not exactly perfect, there might be some tips to do it better. I used 1/2 inch AC plywood which means I had to cut almost all edges. I do not have a table saw or a router bench. I used a skill saw with a straigh edge for a fence clamped to the plywood I was cutting. Consequently not all cuts were exactly the same hence the jig was not as square or precise as one would like. I was thinking that maybe if I used some other type of wood for the top part of the jig I might get better results.
