I have a feeling it's not going to work as well with the scales on as it doesn't seem to rotate as freely as it would without them, but I will continue this through the night and see how it looks tomorrow morning.
I will then take a blade my itself and see how long that takes.

I do have a question. Has anyone tried a very fine silica sand or a silica flour? I would think a silica flour would work quite well but I was wondering if the edges of the grit while very fine would still be too sharp and cause damage?
