Hypothetical situation

[Dean May]

Assuming reasonably level keys and consistent dip, I would use a capstan
regulator to both raise the hammer line and adjust let off. 

 

Next in importance to me is drop, next is rep spring tension ( of course I
rough in checking here as well if needed). Adjust these things on an old
neglected grand and you'll have an amazing result for a quick and dirty
regulation. YMMV

I just worked on a forty year old Weber grand action: shape hammers, rep
springs, let off, the usual. As I was working, a thought occurred to me.
What if I was given one tool, and one hour, what would I do to make the
action play better. 

So that is my question to your guys.  What regulation would you do in one
hour, using only one tool? (You may do two regulations, but you are still
only allowed to use that same tool). Please explain what you would do, and
why? No repairs are needed, and the time does not include tuning.

Have fun.
