In regards to this an all other extension hammers. =20 A few years ago I attended the class of Charles Faulk and his = designing of the titanium tuning lever.. I purposely did not save his = class notes so I could go through the same adventure of trial and error. = However he was my inspiration to go down this particular road. It = inspired me to work on my own along the same path.=20 All extension levers have the same charactieristic. The = compression fitting is at the business end of the steel or whatever = material is used. No matter how long the shaft extends into the handle = it is effectively rendered useless as the flex begins right at the = compression fitting. To me the logical solution for this is to make = the lever not adjustable. I have designed mine to fit as far into the = handle as possible. The more shaft and the more solidly it contacts the = inside of the handle the more positive the hammer is going to feel. I = have chosen to use Schaff's lever shafts which accepts a variety of = tuning heads. In the hammers I have made, I have used not extremely = heavy exotic woods on the bulk of the handle but attached a larger = piece of denser wood to the end so a ball like end is able to be = turned. The handle is also not just uniformly round but shaped more to = fit the contour of your partailly closed hand gripping it. This way it = gives you a choice of grips. 1. Along the handle and close to where the = shaft comes out of the handle or 2. at the ball end and because of the = extra weight of the denser hardwood it sort of acts like an impact type = feel giving you a little more ooomph on moving tight pins. =20 On the matter of the threads of the shaft I believe that = Schaff plates the shaft after the threads are cut which can leave them = sort of rough. Finally the tuning head will cut through the plating and = then the tips can be put on and took off easily. I was always one to = prefer a light hammer as I felt it allowed me to fel more what the pin = was doing or not doing.. =20 Whatver kind of hammer you get, it also needs to be gotten = comfortable with through use every day on all kinds of pianos. Just my opinion. http://www.neesium.com/piano/jahn/ Scott Jackson Jurjens Pianos Wollongong Australia ----- Original Message -----=20 From: DTuner=20 To: Pianotech=20 Sent: Monday, 6 January 2003 4:44 Subject: Juan Tuning Lever Does anyone know where I can get info on the Juan Tuning Lever I will be doing a technical at a PTG meeting this month about = different types of tuning levers Daryl Durand, RPT ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
