[CAUT] Stripped tuning pin head

[Norman Cantrell]

Jim

You are showing you lack of experience in tuning Square Grands as many of them 
have oblong tuing pins.  Basically they are flat on two sides and round on the 
other two.  Instead of a square top that is tapered you see an flat sided oval 
when viewed from the top.  Some harpsichord makers still employ oblong pins on 
their instruments.

Hi,

Sorry. But no experience with oblongs. What the heck is it?

Hi Jim,

I'll give that a shot when my tuning pin supplies come in.  Good idea.  I've 
never used it on 1/0 by 2" tuning pins. Have you had any experience using one of 
the oblong heads?
