I need to shape some 3/4 MDF for guitar molds. I have a router table, PC 7539 router. I am looking for advice on pattern bits (top or bottom bearings), bit diameter, etc. There will be a good amount of shaping, so longevity is a big factor. 1/2" shanks (but I do have reducers).
Honestly, I know very little about pattern cutting and pattern bits, so I am asking the pros. Assuming ignorance on my part is a very good assumption (not all things!! for now, just this issue)
