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.

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

THE-SHOOTIST Anyone chubbin' like me for this?
mailmanmike Since Monday! That's more than 4 hours though, so according to those cialis ads I should see my doctor.
tlane77 I think for a non-chemical chubby it's 6 hours before its time to see a doctor. So you should be good for another couple hours.
splattttttt I wasn't goin to google "chubbin" because I assumed it had to do with fat. The lard type, not the fun stuff. But what ever feelings Jeff's experiencing, then they must be of the fun like stuff...

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.

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.

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) ..
