This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment I have installed two of these sets of Miracle-Wips, one in my own piano and one for a customer. On my own B, they provided a better touch-weight than the Renner wips (even with the springs disengaged), and I was able to remove some lead and easily regulate the springs to achieve an extremely even touch. Now for the bad news - over time, many of the centers have experienced a sudden increase in friction. This seems to be particularly the case with the jack springs, where I measured the friction at between 20 and 40 grams! Another rebuilder I know had the same problem (and was sued over it). My shop partner has also had similar problems with at least one set that he installed. Repinning seems to be a permanent cure for this malady. The other set that I installed has not had any pinning issues so far (about 18 months), but my piano just had two more jacks seize in the last couple of days (the first in more than a year). I would say that I've repined about 25% of them so far. The other problem is with friction in the repetition spring slots. After a while, you'll get a little "tick, tick" sound as the spring slides in the slot. This seems to come with use, and has been a problem on both of the sets that I installed. At Bob Maranelli's suggestion, I applied McLube to the slots, but the problem returned in both cases. I've since tied protek, but too recently to predict the long term success. I also just repined a complete set of Tokiwa shanks that had virtually seized. Touch-weight was well into the 80's! My advice is to stay away from these parts, unless they are going into a piano that is serviced constantly so you can keep an eye on them. - Mark Dierauf - St Pauls School - Concord, NH -----Original Message----- From: Chris Solliday [mailto:solliday@ptd.net] Sent: Wednesday, March 30, 2005 4:53 PM To: College and University Technicians Subject: Re: [CAUT] Re: Leads, Magnets, Springs, etc. The other cost effective, and easier to install, and MUCH easier to regulate option is the Miracle-Wip from Pianotek or Pacific. These are made by Tokiwa and have excellent centers, adjustable heel positions forward aand back in a slot, etiher angled or straight and once you have used an adjustment screw for setting the weight you probably won't settle for anything else.

His new invention or application of magnets to piano action is called "Magnetic Friction Reduction". This is viewable at the inventor's website as peviously posted. The new information is about retrofitting an action to this system. While the cost is less than the previous system used in the Fazioli, it seems to me it would be less costly if replacing whippens to go with the new Turbo-whippens w/assist springs, rather than buy a set of new whippens, and this retrofit kit, and have to retrofit each whippen AND hammer shank. I think as nice as it sounds, I'll have to pass. Until someone manufactures replacement parts w/the magnets already installed, at a price comparable to a set of turbo whippens, I don't think this is a cost effective way to go. Maybe one of you deep pockets guys will give it a try and report back? Anyhow, here's the hot poop on this hot and magnetic topic: >>>>>>>>>>>>>>>>>>>>>>>> The MFR system is indeed available as retrofit kit. The retrofit kit contains magnets, magnets already glued on the adjustment screws, two magnet positioning tools and glue. An mounting instruction manual is also available and will be send by e- mail. The price is Euro 600,00, exclusive transportation costs. The estimated time needed to install the system is about 1 or 2 working days. The kit can be ordered by the firm Evert Snel: e-mail: info@evertsnel.nl I hope I have sufficiently informed you, if not let me know. Best regards, Hans Velo H.J.
