Jim, John, et al, In addition to using the #7 bit recommended by John, I use a burnishing tool made of a piece of brass all-thread, turned down to appropriate size for a length of about 1-1.5" from the tip, and fitted to a 40watt soldering iron. The heated rod not only correctly sizes the felt, but burnishes it as well, providing a smoother bearing surface for the damper wire. (I blatantly stole this idea from Susan Graham.) Best to all.
