on most materials I use abranet, starting at either 120 or 180 grit, up through 400, then switch to MM, 1500 through 12000. When using mixed materials (usually bloodwood/maple or bloodwood/holly for the Texas Flag pens, red dyed maple/holly for Ken's stars and stripes kits, or blackwood/holly for the piano pens) I only use abranet up through 320 in order to minimize contaminating the lighter wood with sanding particles from the darker wood. I'll use a dipped lacquer finish, knock down any rough spots with the buffing wheels after coat 2, put on two more coats and return to the lathe for wet sanding starting with 2400MM up through 12000.
