---------------------- multipart/alternative attachment The easiest way to increase touchweight on an upright is to install Jiffy=20 Leads. The benefit of these is that they are equally easy to remove or alter their= =20 position. Make sure the action is properly regulated so as to be certain that weight= is actually all that is desired. I think it was mentioned that having the=20 dampers lift a little sooner will add their resistance sooner in the keystroke thus raise= th touchweight, check the damper spring tension as well as well as the jack= =20 spring and hammer return springs.
