basic regulating question

[Alan Barnard]

True enough BUT with worn felt and leather, etc., often you need a bit more of a wink if for these old beaters to work right when it comes to jack resetting and hammers not bobbling. I'm sure if you can do a full regulation, you can get everything working with almost no lost motion, but in the field, on the run, with worn hammers, etc., sometimes you have to employ a bit of sugar, chocolate, butter, and evaporated milk, i.e., fudge.

There should no space between the top of the jack and the hammer but. You eliminate this space by adjusting the capstans. The adjustment should be so that when the hammer rest rail is pulled back, there should be just the slightest movement back of the hammer. But the hammer should move forward when you push the hammer rest rail forward. If the hammer rest rail doesn't move, you can still check for proper adjustment by barely touching the key, and watching the catcher. It should move almost instantaneously.
