Hi Jim,

Yes, Paul is doing some good work. We have developed an approach
which seems to be quite similar to what Paul is doing. After
polishing the inner surface we are EN plating the agraffes and heat
treating. The results have been quite good. The piano we took to
Rochester last June had agraffes with this work.
