---------------------- multipart/alternative attachment HI Boy & Girls WOW ,All this talk of unison cracking made my brain numb so I thought I'd take a different road for fun to distract you 'all I my quest to learn all I can about Balancing actions , choosing the right parts & balance weights and such has led me once again happy to be reminded that I Love the Steinway company for providing me yet another oppurtunity of endless proportions & to make Bank having fun making the differing macinations & incarnations of the illustrious Steinway actions work properly. It is a challenge & honestly if wern't for them I wouldn't know any thing about this stuff because they have given me endless oppurtunitys ..............................etc. So I'm grateful. You disadvantaged European guys probably don't' get this rich opportunity with the German Stwy engineering. unt I heer dee have zee jeegs & feexteures over daer too so theey make zee actions uniform ...shhhhhhh New york Might find out! You gotta watch out for these factory tricksters. There always coming up with a new action brain storm. Seriously though it is what it is & I enjoy making a living fixing this stuff. It give me creative license I'm currently working over a wonderful sounding 1966 Steinway B with the keys -O- lead syndrome. Interesting case study.. The high ratio action always has it's tell tale indicators. . i.e.. 48 mm blow or longer & .375 dip, or less at the pin & keys full of lead starting at the balance rail Installing the new shanks & flanges side by side with the old ones revealed the location of the teflon enraptured center pin to be roughly 146mm above keybed. 145 to 146mm ....This fairly typical However the new parts pin location is almost 2 mm higher. The pin sits low in the Teflon flange. Why? dun no Hmm... The hammers were bored short for a B at 1 3/4 " or 46 mm. which was correct for the old parts. The wippen pin height was also higher than the standard 3 1/4 inch by more than 2 mm. The beginning action ration was 6 to 1. with 16.5 knuckles. Using 17 mms knuckles with the different pin placement made the spread a squeak wider 4 7/16ths but still brought the ratio down to around 5.7ish Still to high. I also chose to reduce the action height by whittling away the action cleats 2 mm to get the center pins & hammer bore into a more typical range. The capstans fortunately will be able to be moved forward 2 or 3 mm which will bring the ratio down closer to 5.5 to 5.3 which would be really great. At this ratio I can of course remove lead, reduce inertia , increase hammer bore length, Increase hammer weight a bit & improve regulation parameters to 1/3/4 ish blow & .390 dip, which is more typical for Many Stwy pianos. It was suggested that another fix for this would be to get a modern stack & strat over.& I beleive thsi idea has merit but wasn't really necessary. Any body do this? All this change of course allows a pianist to access the tonal potential of a great instrument, in this case, of a really good original B belly set up. It's a lot of fun. By the way the Wurzen hammers on this piano were right where they needed to be right out of the box. Power without noise & lots of color. No needling. It's to good to be true......naaahhhhh! Happy Saturday Dale . ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
