This plate receives new hitch pins. With a nail punch like this, the old pins are punched out from underneath. Pay attention not to enlarge the holes.

This is another ongoing tribute, in my life, to Piano Technology mentor Mr. David Betts and Ms. Debbie Cyr.

At the piano shop, the owner prefers DMT diamond stones. They are heavy and solid. I work with his set the best I can but found that the course stone looses its grit very quickly, and quickly it becomes close to "fine". Recommended by fine woodworker Mr. John Cameron located in Gloucester, MA, I bought a set of water stone. They work much better, not loosing grit. The stone brand and price vary greatly. So far, this set of Naniwa water stone from Sharpeningsupplies is working well.

The preparation takes about an hour yet it is essential for a good stringing job without much damage on the piano case. First, the top surface is covered by blankets and cardboards for protection. The little rings to fasten blankets are chopped from PVC pipes.
