upright touchweight

[RicB]

Hi John

Increasing the backweight of the keys will only increase BW. That is to 
say that both UW and DW will increase.  If you bring your DW up to 50 
grams this way you can expect an UP of around 40 since you started out 
at around  40-45/30.  That yields a pretty high BW and the way I read 
your post I dont think thats what you are after.

Increasing friction can be accomplished by making sure your hammer and 
whippen centers are tight enough, making sure key bushings are tight 
enough, and balance pin hole is not too loose.

Other things that can yield a <<sense>> of increased weight is damper 
timing, damper spring strength, and to some degree jack return spring 
strength.  Increasing spring strength tho has the same effect as putting 
more leads in the keys tho... both UW and DW are increased.

Hope this helps a bit.
