<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> Hi Richard. While I agree with your basic assessment I have to go back to what I said at the very beginning of this whole line of threads. You are going to have to decide if whatever gain you can achieve in touch behavior is going to be worth the effort of repining and eventually re-doing the weigh off.. and be able to defend the cost to the owner...cuz I doubt seriously you are going to get Steinway to pay. Sure, such light hammer flange friction will perhaps cause you to make a few different compromises in action regulation then those you are used to in order to achieve a decent enough play. But getting a fast enough repetition and enough power should be plenty doable, and there are no doubt Yin sides to whatever Yangs we are looking at any ways. So before you get yourself in a position where you are going to recommend that the Huskers foot the bill for repining and a new weighoff....I'd make sure that the pianists are simply not happy and cannot be made to be happy with the touch unless you make the change. My advice is to get a feel for regulating these actions and observe pianists reactions over time before bringing on Dracon. Cheers RicB btw.. you can back off a << rats tad >> on rep lever strength when hammer flange friction is low... this will counter to some degree some of your concerns and will not compromise rep speed.   "Richard E.

But setting the drop low works against good repetition and setting the checking high reduces power.  Both are more difficult to set and, I think, less reliable over the long run. To review what some seem to be saying over the past few weeks, does all this mean I'm going to have to repin all new Steinway flanges?  Worse yet, do I have to weigh off new actions because the factory weigh off was done with loose pinning?  </blockquote> <blockquote TYPE=CITE>  Richard West, University of Nebraska _______________________________________________ caut list info: <a href="https://www.moypiano.com/resources/#archives">https://www.moypiano.com/resources/#archives</a></blockquote> -- Richard Brekne RPT, N.P.T.F.
