Correction: "in order for the jack to return under the hammer butt..." -----Original Message----- From: paulrevenkojones at aol.com To: pmc033 at earthlink.net; pianotech at ptg.org Sent: Tue, 25 Mar 2008 12:24 am Subject: Re: Steinway repetition problem Just a thought, William, based on what you said. The capstans displayed "free play", what we call lost motion, which later you say you corrected. Lost motion seems to be one of the least understood upright regulations. You have to have zero in order to accomplish some other regulations, then you have to have some to accomplish some others. In the end, you have to have some lost motion (maybe in the range of 1/32", or a wink of the whippen or backcheck) in order for the hammer to return under the hammer butt. Have you got the capstans cranked up too high? Just a thought.

I'd go for replacement. Also, check to see if the damper lever lift felt (end of damper lever) and see if there are divots. The felt on these is very soft and not woven. Sometimes the felt has "melted" something onto the spoons which causes them to become rough. Then they "carve" holes in the damper lift felt. You could also strengthen the hammer return springs. Take out some of the shims from the spring rail, or replace the springs with stronger ones. All the springs are suspect. A stronger jack spring will help too. Easiest is to rebalance the keys. I hate jiffy leads, but in this case, you might need some. Good luck.

I have a customer with a Steinway 42 inch vertical , serial, 331374 that looks like it came out of the 60’s. The piano has what I think to be a Pratt Read action and the problem is with the repetition. This is one of those pianos that have very little mass weight in the keys behind the balance rail. When I started with it, there was a lot of free play in the capstans and of coarse, I thought I would improve it by adjusting them correctly. Now the keys are stalling and I would like to solve the problem. I did take the action out and: shape hammers, clean, lube, tighten screws. I replaced the action and adjusted: level, dip, let off, back checks and like I said; capstans. I have had this problem with other Steinways like this one, but am getting tired of it and would like this one to work. I know I can add weights to the backs of the keys, but that would make the touch heavier. I could take out weights from in front of the balance point, but would like some suggestions on how to remove them carefully, so if it doesn’t work and decide to replace them I can. The customer has been patient and given me my space to create the magic we do, but if it doesn’t play right, then no one is happy. Thanks for any help in advance.
