I'm sure you all caught the minor error in the articulation of my question yesterday, but the issue is still the same. I should have said that by moving the stack out and the hammers in, I could then move the capstans out about .6mm, not .25mm. I know that I will just have to experiment and compare different solutions, but my question was really if anyone has some good ideas, opinions or data comparing change in key ratio with change in shank leverage or change in wip ratio, as Kieth suggested by moving the heels? ________ At 4:52 PM 6/20/95 -0600, Kam544@aol.com wrote: >Will someone please re-educate me as to the method of placing a string or >thread from the hammer flange center to some other action part to determine >appropiate alignments? > Keith, I don't think I am able to quickly put together a complete, accurate and clear demonstration of whatever I have so far learned of proper action geometry here on the internet. Perhaps someone else will jump in with a summary for you. If not, the Convention next month will be an ideal place for you to grab someone and raise questions. I think that the CAUT forum will cover this subject at an advanced level this year and I regret not being able to go myself. In the meantime (and forever after) I recommend studying Walter Pfeiffer. Much of his work is translated into English and I would start with "The Piano Key and Wippen". There are other books too, but this will have more than enough to chew on. Has anyone ever moved heels on Steinway wippens? Dennis Johnson St. Olaf College
