We learned this at Oberlin 2 years ago for the Steinway seminar. I was amazed how much better it sounded.

Was-----Yamaha Hammer Suggestion Randy /Tom You mean like this S & S Model B? 95 % of our steinway hammer lines look sometyhing like this. They arne't the only ones that benefit Dale Erwin Randy With regards to the "sweet spot" it's a matter of experimenting with several guide hammers with only a dry fit to the shank. Play around with the action by sliding it in and out ever so slightly. It's rather obvious when you've arrived at the sweet point as the tone will spike once the true spot is found. I find that about 90% of the pianos you are safe with a straight hammer strike line from 1-88. That's how most factory jobs are completed. However I find that the older Steinways can benefit from a varied line from #70 and up. You just need to experiment and find the general parameters and off you go.

The attention to detail can be overlooked for sure by some and end up with a bigger problem. The hard work starts at the beginning no matter who you get your parts from. Its the detailed work that pays off. I still hear of techs who buy, for example pre hung Steinway hammers :( . I did that once early on and, oh my gosh!!!Never, never again. I would be very interested in how you or anybody else find the proper hammer line/sweet spot. I can ALWAYS learn something. I have one of those diseases that I have to keep learning. There's just so much out there that I can't help myself. I live in the San Francisco bay area and I wish there was a better way for me to continue to learn after 15 years of this. I have it.
