basic regulating question

[Fenton Murray]

Hmmm, 
You didn't mention capstan adjustment, my first thought, oh yea you did. I assume you mean the amount of escapement, or aftertouch is different. This can be tricky to get right, but is at the core of very high level regulation IMO, keep at it. A very small difference in key dip or capstan adjustment or let off or key height or hammer bore distance or hammer filing or or or or can make a difference, maddening isn't it. Start with dead level keys, precise dip and capstan adjustment, and work from there, if you have the patience. Old uprights are going to give you fits if you want everything to come out to spec. The butt leather is usually worn so setting lost motion is all over the place. Chucking keys and everything else is conspiring against you.

  Greetings,

             This may seem like a dumb question but after I level the keys and insure even key dip in an upright, why dont all the jacks have the same distance between the jack tip and the hammer butt after I depress the key and hold it there? Are my capstans uneven? Maybe its been too long a time since I learned this, and having only done about 4 regulations, maybe I am not remembering something.
