Not DOWN weights...grin.. frontweights... the only reason suspect them is that I have
compared them to Stannwoods guide to maximum front weights... and they are heavier then
those... by 3 to 8 grams I think I found out... in anycase they are above Stannwoods
recommended maximums.

All this is done first time through. Hammers after proteck swing 7 to 9 times... plenty
loose. Tap test for whippen flanges... again plenty loose. Pins are slik as
willys..er..wait.. anyways they are fine. I think I have some drag centering around the
knuckle / jack relationship.. I will know when I start regulating I suppose. Friction is
pretty much under 15 all the way... shouldnt be tooooo bad there... I thought there were
some odd unevenesses... C4 for example has some weird numbers compared to the rest...
high front weight.... accompanied by a drop in BW of course... sticks out like a sore
thumb really.  Then also F4 C5... front weights here dont tail off much from the middle
of the key board... the strike weights for these curve off slower then a Stannwood curve
would, and it looks like they used this combination to "force" the BW to tail off. But
then that tendency is reversed again in the last octave... where BW rises after FWs tail
rather suddenly off.. but remain well above Stannwoods recommendations for maximums...

Grin... thats too time consuming for this job...and I can only go one way with that
proceedure. I suppose I could take a look at it tho.

I'll let you know more tommorrow, but in the first instance I will be doing friction
things and very moderate SW reduction.... the rest is for diagnose.. I get to play with
this piano a lot in the future....:)

Thanks for the good advice as always Newton... nite nite..
