If there were questionable ridges, I would have filed them down first. The piece was slightly bent so it didn't have full contact with the magnets. So I had to take light cut to flatten it, lots of light cuts, didn't want it flinging off the chuck.If there were raised ridges on the piece you're fly cutting (if it was around the jagged inner edge, for example), do you do a single pass slower or do multiple passes, each decreasing in height?
Or either approach, depending on the height of the ridges?
