We have a lot of aspen up here in the northwoods (most people call is popple around here) and I've started playing around with it. It is relatively soft and very stringy so there is a lot of tear-out. I generally turn other hardwoods with either a 40/40 grind or a sweptback gouge with a nose angle of about 50-55 degrees and get a fairly clean cut. Anyone have experience using other gouge angles/grinds on aspen?
