<HTML><HTML>Greetings,              I g= ot a really good idea!  I have done about 5 hammer carding & needli= ng jobs for customers who own old, old uprights and I take the actions home = to card and do basic deeep shoulder needling.             &nbs= p; However, when I return the action  to the piano, I find I need to cu= stom or individually needle the hammers to tonally match/blend the octaves, = or rather, make the side by side notes sound homogonous/alike next to one an= other, blending the sections.             &nbs= p;  With the action in place, when I attemp this, my voicing tool's han= dle gets in the way and is too big to use in the small space between the ham= mers and the strings. I don't like the idea of swinging the action back and = forth to needle, listen, needle, listen...etc.             &nbs= p;  The great idea is to dismantle the voicing tool, saw off the 1" or = so handle insert thereby having just the needle (cartridge?) head in hand so= that I can work quickly with the upright action in place. Is this a good id= ea?  Julia Gottchall, Reading, PA </HTML>
