slow speed. don't skip grits. once you get it going you'll figger it out......be sure and hold your lower lip slightly left of your upper lip [unless you are left handed of coarse]:rotflm:
Keep a light touch and let the sandpaper do the work. When going from the hard to soft wood in a bowl you can get quite a "dip" if you apply a lot of pressure. Make sure your vacuum works.
That all I screwed up so that’s all I can add.
Oh, make sure you do not heat up the wood too much. It is easy to do since your fingers are not in contact. Add many heat cracks to my list. And melted grippers on the pads. And...If I remember the others I will post again. I'm sure I messed up more than those few things. That is hardly even a list for me. :rotflm:
