Baldwin verticals are notorious for extremely tight balance rail holes an=

key bushings. First lift up the wippen off the back of a sample key and l=

up on the front of the key. You should be able to lift up a quarter of an
inch or so and have the key return without any problem. Try easing the
balance rail hole and front and balance rail key bushings if they seem ti=

 Be very careful not to over ease the keys. I have found 30 or 40 year ol=

Baldwin consoles with sluggish actions due to this very problem. If you
still need to use an alcohol and water mixture to size action centers, yo=

can use denatured alcohol (methanol and ethanol mix).=0D

I went to tune for a customer and they commented about their action not=0D
being the same sine they moved from British Columbia to Upstate New=0D
York.  When I pressed down on the sustain pedal, the hammers would only=0D
hit the string once and then not repeat.  I think I need to loosen up=0D
fome friction points, and if you can think of where this might happen,=0D
let me know.  I have to take out the action.  IT was a Baldwin console=0D
upright. Nice piano tune.=0D

Some fellow technicians said that you can use Methanol to loosen up the=0D
action friction and this has worked well for them.  Do you know where=0D
you can purchase Methanol?=0D

Any ideas, suggestions would be appreciated!!!=0D
