This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Yes, Dale I've been finding that the new S&S parts seem to produce better results than either the Renner or Tokiwa stuff, but I do like the overall quality of Renners more, and they're also considerably cheaper. I'm glad to know about the Abel parts for Masons and will be sure to add them to my bag o' tricks. On my B I could easily have forgone the helper springs, but I wanted to give them a try on my own piano before experimenting with someone else's - Mark -----Original Message----- From: Erwinspiano@aol.com [mailto:Erwinspiano@aol.com] Sent: Thursday, December 04, 2003 10:16 PM To: pianotech@ptg.org Subject: Re: Squeeking rep lever springs on Tokiwa wips In a message dated 12/4/2003 1:58:44 PM Pacific Standard Time, mark@nhpianos.com writes: like the parts, and love the eveness of touchweight that I was able to get on both pianos with the adjustable helper springs. One piano - a Mason AA with Renner wips - went from the mid 60's (grams) to the upper 40's in the middle after the switch over, and I removed 6 lbs. of lead from the keys. The customer was beginning to have muscular problems that limited her practice time but can now play for hours pain-free. The other set went on my own Steinway, and even without the springs I got better touchweight & friction numbers than with the Renner parts. I do have problems with checking on my piano that disappear when I swap out samples with Renner wips, though. Although they appear identical in the important aspects, I suspect that the Tokiwas are shortening the action spread just slightly, but I haven't checked it yet. Can someone remind me of what the spec is for S&S action spread? - Mark Mark I'm not a big fan of helper springs & usually find other ways to handle the weight problems. I have found that one tool to have are the Abel parts for Mason/wessell, nickel & gross actions that are a perfect fit for many & they are the only ones who make an 18 mm nuckel placement. These parts will work well on those that originally had this configuration & on some others depending on key leverage & action spread. Until now no other supplier has provided this dimension of part. Also I like the fact that the center pin location is not moved out as per the Renner parts on there Steinway shanks. The Tokiwa parts are a good fit except that the overall height is taller than original factory wippens which requires techs to lower the capstan perhaps further than the magic line calls for which, can also increase touch weight. On Steinways I gave up & just use the factory wippens as they fit every piano they ever made really well. The Renoir whips tend to be too short & jack placement is really ideal for primarily there 17 mm knuckle execution. Just MHO based on trial & error.
