Andrew; I restrung a 6'2" Hazelton some time ago that had a cracked plate in two places. It cracked because of the stress put on the plate that was bolted into the structure and the pin block in a position that caused the two struts to crack in an obvious weak spot in the design. I splinted the crack and reinforced the strut by extending the splint past the weak spots. I used PSCALE to check the scale and converted 6 notes above the bass break from trichord plain to bichord wound. I still have the before and after scales that I could print out for you if you like. I'd have to mail them to you, cause I'm not sure I could get them out on e-mail. Call me at 1-408/984-0482 if you like and I can tell you more about the stress the plate was in. Best to call 8-9 am pacific daylight time. > [Original Message] > From: <ANRPiano@AOL.COM> > To: <pianotech@ptg.org> > Date: 6/28/00 8:36:42 PM > Subject: rescaling tension > > I am attempting to rescale a Hazelton 5' grand I had asked you all about > awhile back.
