After the pins are smooth, I always spray them with McLube 1725 (front and back pins). I also graphite/burnish or McLube the whippen tops, brush the under whippen felt then iron it lightly then brush the felt with microfine teflon powder, brush the knuckles then brush on teflon powder there, too. You can also put drops of Protek on the key bushings. SLICK!!!!!! This makes a dramatic improvement in the customers eyes. Careful not to overdo it for the customer that likes a heavy touch. I also mic the balance pins and ease the balance hole if needed. I put a drill bit that is a few thousandths larger than the pin chucked into a T-handle BACKWARDS. I then slip the bit into the balance hole from the bottom. I can grab a few keys at a time and do them very quickly. Carefull you have the right size bit - no pully keys.
