First problem - The hole in the router table is only 3.2". But the shank on the bit is long enough that I could put it in a full inch into the collet and still have it above the router table. I then put the panel on a 1/4" plywood so it lined up with the bit. Is that an acceptable method?
Second problem - After setting the router to the minimum speed, I tried a 1.5" cut. It was immediately obvious that it wasn't going to work, but that was as far forward as I could move the fence. So, I clamped some 3/4" stock to the fence and tried again. Better, but still no good. I added a 1/4" piece to the fence. With a 1/2" cut it worked, but still not very well. Am I doing something wrong, or is a 12a router simply not powerful enough to handle a bit that big? (or maybe minimum speed is too slow?) If I have to make 1/4" cuts, a whole door will take forever!
