Building a custom LPK

mmmmmmmm i think you should just buy one. clicky pen upgrade and any other kind of non-manufactured paintball gun upgrade will ruin your gun. If you mess up you lose more than if you just got the lpk in the first place. save up some dough. sell some junk. buy it.

look for TinMan's marker in the Marker section, he has a nice one

Anything lower pressure than the stock, and the spring tension needs to
be lower. It's not an exact thing, you can fudge it. Tippmann's setup is
just a ratio between spring tension/flow/hammer mass/production cost
that works for them. My 98's LPK consists of Tippmann's LP valve setup
and a heavily milled bolt. I've used a Dark Horizons Titanium hammer in
there too, that works fine.

Mine runs around 400psi and very quiet.

Good writeups on this at model98.org. No exact volumes or spring
weights or anything though.

The volume of the valve isn't really the issue so much as air flow. The
channels in the LP valve are MUCH deeper than the stock. The volumizer,
however, is about 1" diameter and 2.5" long. Walls aren't too thick either.

I imagine you could cut the stock valve spring down and stretch it, or heat
it to soften the temper. Worst that can happen is you have to get a new
spring.

Hope that helps.

I did what you suggested, Monk, and bought the kit. I have another question
though: How do I remove the low pressure chamber from the vertical
adapter without destroying either?

Thank you for the help Monk. I think I'm finally finished. I'll post pics in the
gallery.
