Me too Bob, that's a great arrangement. Susan it keeps the #1 chord always under the middle finger, the # 4 chord under the index and the # 5 chord under the ring finger. I am no fan of the three row harps but that is because I have large fingers. Smaller fingers may find this a good set up to have three rows.

Ducco cement will glue down the felts if they come loose and it works on the chord buttons on the two row (B Model Harps). The C models or three row harps generally don't glue down the buttons as the big chord bar cover holds them in place. I have never seen a three row, 15 Bar conversion before and they may be a different kettle of fish.

Go back and search Autoharp threads. The felt has been addressed before. There are two camps on using silicone to level the felt surfaces. People are either for or agin it. Those for have no trouble with it. Those against tend to be rabidly against. I have used silicone successfully on many harps. EMail me and I'll send you a description of what I'm talking about and I'll out line clearly the pros and cons.
