[pianotech] Ivers & Pond Upright #24422 (John Ross)

[Sigurd]

After you have replaced the but plates the next thing to happen is the brass 
rail tongues will start to break. To keep yourself out of trouble remove the 
brass rail with the but plates still fastened. Have the brass rail heat 
treated. Heat treating will soften the brass and you won't have any more 
cracked brass for as long as you are in the tuning business.
