<html> <body> Hi Ed,              Grip the regulating button with a pair of parallel pliers and drive the screw further into the button. A very common problem with Baldwin Grands. SF10 should regulate at 1 7/8" blow at .400" dip.   If you still have a problem, check the magic line. capstan should bisect the line at half blow. It would not be the first one that I have found with the wippen rail set incorrectly. Don't have my note book with the spreads handy.  But setting the spread at half blow, and the magic line, usually works for me in most cases. Hope this helps.

BUT, there is an action problem. When dip is set to a standard block (Steinway), there is very excessive aftertouch. The owner says it has always been like this. When I lower the capstans to decrease aftertouch, the shanks knock on the repetition lever regulating screw. The only choice is excessive aftertouch or shallow dip. The prof. does a lot of performing, so he wants standard keydip on his practice instrument. Something is wrong with this instrument.  Possibly the string height is low, and they let it go? I could shorten the hammer bore distance...or just file down the hammers? Is there some regulation, shimming or rail adjustment I'm missing? Thank you. Ed Sutton</blockquote></body> </html>
