Nope, didn't even need a fret level Wokks, just goes to show how how important a flat fingerboard is.
I just cannibalized a couple of my Bunnings files for the fret edges. One to get the flush edges was chopped up, and stuck to a block I fashioned out of silkwood, the other for the bevels I ground the sides smooth so it could run on the fingerboard without damaging. Seemed to work sweet.
