Query: Poor fit until I used the Dremel tool on it.

The relief area where the two mounting screw holes are was too tight and would not allow the insert to sit flush. Used the dremel to open up the area a little bit and now it slips right in place. It could be due to variations in the saw, 10" Deltas aren't exactly "high precision" machines. Any way, it fits now and serves it purpose. The price was worth not going through any aggrevation of trying to make one.
