In a class in Austin, TX, Bill Garlick described the use of this tool by the NY technicians. He called it a "tomahawk" tool because it is kind of shaped that way. He said (as you might expect) that this can certainly be over used. Occasionally I see a key from a NY piano that has a dent from the half-round bearing where the wood was crushed by an overly enthusiastic use of this tool. I think with the bearings used by NY, causing a very narrow contact point, the wood is easily crushed. dave *********** REPLY SEPARATOR *********** On 7/30/00 at 10:13 PM markbolsius@optusnet.com.au wrote: >In my last rush of responses ...

The lever uses the pinblock to rest against as you gently press block against the key until you get the result you need. It has definite limitations...it really depends on how many punchings are under the key...the more there are the more compression is achieveable. > >I wondered about the longevity of the "adjustment" but they assured me it was fine...as they would! > >If anyone's interested I'll attempt a drawing and put it on my website... email me privately and I'll determine the interest level to see if it's worth the trouble > >...I realise my description lacks clarity...Sorry, but it's Sunday night here...my brain atrophied a few hours ago. > >Nite all >Mark Bolsius >Canberra Australia David M.
