One safety note for you. If you try to saw up a bowl blank that is already round to make it shorter, you need to attach a side stabilizing board. Round things and downward motion are NOT good bedfellows....
Don't ask me how I know this....
I don't have to ask. I tried to thin out some segmented rings. I thought I had a jig all worked out.
I did not.
Amazing how much downward pressure that blade can provide. It puts a new spin on things for you, that's for sure.
