That way the tuning hammer can be parallel to the straight side of the piano (it would be at "12 o'clock" if you were still sitting on the bench), and your arm can miss the lid prop. You can also see the strings better, looking straight down at them. (Well, I can ... sorry about that.) Unisons in the tenor bichords -- sometimes the wire is just annoying, and the unisons won't come clean. The best you can do is try to make enough peace between them that they are no more obnoxious than they absolutely have to be. Choosing a tuning tip and head, I prefer to have a short head at a steep angle. Schaff carries a 7/8" head at a 15 degree angle: <a class="moz-txt-link-freetext" href="https://istore.schaffpiano.com/istore/product/13F">https://istore.schaffpiano.com/istore/product/13F</a> I believe the head on mine is at 20 degrees. I bought it at a convention. Most of the time this will clear the struts, but if it won't, use a tuning tip extender, also from Schaff. You can put it onto the tuning pin, and just put your tuning lever onto the top of it. <a class="moz-txt-link-freetext" href="https://istore.schaffpiano.com/istore/product/3129">https://istore.schaffpiano.com/istore/product/3129</a> Hope this is of help.

I know sounds odd for a piano tech to be missing a piano lol     Speaking of pianos now, have any of you ever found the last two or three bichord strings in the tennor problematic when striving for a clean crisp unison?  I know much is said about hammer control, but is there ever a possibility that some tuning levers are inferior to others or does tuning strictly have to do with hammer control period no matter how expensive or inexpensive of a hammer one uses?  Is all of this talk about different levers a matter of preference?  I have the schaff 21c lever and I bought the universal head and tip that are one unit because I needed a better head for clearing plate struts in grands when tuning, but for whatever reason the new head doesn't screw on tight.  It tightens so much loosens and then gets too tight again. I'm hoping I can get this off again.  Also what have you found that works when tuning grands in the treble section where the rim and often the lid support get in the way and you have to get in a twisted position in order to tune up there.  What are your thoughts on all of this?  Marshall 215-510-9400 <a moz-do-not-send="true" href="http://www.phillytuner.com">http://www.phillytuner.com</a> </div> </blockquote> </body> </html>
