Several months ago a woodworker I met on another forum was helping a lady sell her deceased husbands tools. I had bought a few things and he asked if I wanted a box of router fences, and without hesitation I said sure. I think this might be the same or similar to the Oak Park system but the box is marked West Oak's Inc. spacer fence system. Included 1/4", 3/8", and 1/2" fences, a small block with a dovetail and straight grooves and a longer block that has a straight groove and a half dovetail. The 3/8" fence has 4 holes and the other 2 have no holes.
Since only the distance matters from the fence to the bit, I assume that I could drill and mount one end of the fence in the back of the fence then using an appropriate sized brass bar adjust the fence to the bit, then mark drill and mount the front of the fence. Should the fence in the table be slightly sloted to allow minor adjustment? Are 4 holes needed in each fence to secure to the table, or will one at the top and one at the bottome be good enough?
Thanks!
