The builder of this harpsichord is a retired Cornell engineering  
professor named Al Clark. He has been a woodworking hobbyist for a  
long time and has built some beautiful pieces. Several years ago he  
decided to try his hand at making harpsichords. Attached are pictures  
of the instrument we have. It is his second and modeled after Tibaut.  
As you can see, it is not an amateur looking case. He even made his  
own jacks;  wood + no adjustment screws = yikes! :-)

While Jon's suggestion of using zither style pins has crossed my  
mind, I want to preserve the look Al wanted for the instrument. He  
told me what the pinblock material is but I cannot remember if it was  
oak or walnut. I'm not a builder but I don't think either of those  
woods works well for a pinblock. Not sure where he got the idea to  
use an open pore wood.

I am fairly proficient with wrapping a string around the current pins  
without becket holes; I just don't like it. It is a bit quicker with  
becket holes and if I can get the pins I want I'll be a happy camper!

I am aware that whatever I eventually do, I have to be careful of the  
pin hole size. The point is well taken that there is the possibility  
of splitting. I have measured the pins Willard uses and they are  
similar in diameter to the thicker part of the tapered pins and, they  
are the same height. If I can get pins like Willard uses I do not  
expect to modify the holes too much.

Many thanks to Bill and Chris for connecting with Willard and David  
Doremus for the Marc Vogel link!

Regards,
Don
