<html> Hi Gang, The broaches I developed are sold by Schaff pPiano Supply, I think it's part #220. The include some brief instructions on their use. The hard part on upright pianos is taking parts on and off the rail - the pinning goes pretty quick, and when you are done you will be very confident that the action will perform well. Alcohol / water sizing is good as far as it goes, but unfortunately it doesn't always treat the real problem.  I size the bushings if I feel they are spongy (bushing cloth is too soft), then repin the parts with a larger pin to get a nice, solid center that moves freely. If the bushings have been contaminated with inappropriate lubricants, or if the pins themselves have burrs or corrosion, then the sizing will give temporary results.  In the end, your action refurbishing job will not be very good for your reputation!

Can I assume the broaches are the uniform diameter broaches available from the supply shops? Never heard of the anvils, but sound interesting. Thanks.
