Prior to my shelling out $$ for buffing equipment I would ask a couple
questions.
Let's assume I have turned my bowl and sanded to around 220 or so. I
then apply some Watco Danish oil, or BLO. I sand more to around 500
grit. After sanding to 500 would be the point to start the buffing,
yes? After buffing I could then apply shellac if that was my
preference, yes?
