Albert, David is spot on. Make sure that the becket is at length and wire correct at the TP hole. That being said... I recall an instance where the beckets were slipping. The TP hole seemed to have some lubricity. Perhaps from short degreasing of the cutting oils in the factory. Thought I can't be certain. The issue was resolved by running an additional 1-2mm piece of wire beyond the pin (hole) and bending it opposite of the winding direction. This was similar to a practice used by Baldwin. I believe,they used a mechanical stringing device. Others on the list might be able to confirm teh equipment used. This technique effectively makes Z through the pin. Although I personally don't care for the finished look, it did stop the issue without having to totally repin.

Are you using blued or nickel and are you sure that the beckets are extending far enough through?

However, since I began restringing pianos with them, I have had to replace anywhere from one to six treble strings per piano because beckets have slipped. I've never had this happen before, and I'm wondering whether anyone else has had a similar experience. Cheers, Albert The new Internet Explorer® 8 - Faster, safer, easier. Optimized for Yahoo!
