So, let me get this straight.
I would need a tuning fork in order to see if the valve train is in sync?
Bogus! Another tool to buy.
Does Palmers sell this doodad?

And so, I'm foiled again!
I always thought that for 12g efficiency, t'was best to use a heavy hammer, light main, heavy valve spring.
No wonder I'm buying twelvee's by the case

That's mostly true though, just the same.

It's all a juggling act to keep the valve closed as much as possible.

I did pick up some handy elf magic though, now to find a beast to test it on.

I'll test it for you

I always wondered why my PMI 1 sounded like a B Flat

Different combinations can have similar effects.

A heavy hammer and a light main spring will mean a heavier mass traveling slowly. A light hammer and a heavy main spring will mean a lighter mass traveling faster. Both can impart a similar force.

But lighter will be better. Like the fluted Nelson hammers that are all the rage.

It was always a little tone-deaf.

So, hard vavle, light hammer, hard main? I might have to mess ith this when i get the chance

essentially you want the valve to be as stiff as possible so it doesn't stay open any longer than you need it to, and the hammer and mainspring combination to hit it just hard enough to give you as much air as you need to get shooting velocity.

So, you want to either shove something light into the valve with a lot of force, something moderately weighted with a moderate force or something heavy with a bit of force.

The reason something light is most desired is so that when the hammer bounces back off the valve pin you don't want it to have enough mass to bounce back off the mainspring hard enough to open the valve again (see:hammer bounce) ..
