I use the mop sander to on my drill press. You just have to go very lightly against the mop or it could take the piece right out of your hand. If I have a lot of fuzzies, i sometimes use those long grill or candle lighters.
Oh yae, Oak can be hard cutting. What size blade did you use. Try some in cedar. They really look good with a few coats of poly on them. It brings out the cedar plus it's a little easier to cut.
