Best trade ever. 😉

glad you got it working ! Nice use of them there new spare parts as well

After trying a lot of different springs and a couple different hammers, I've ended up at around 270-280psi with the IVG in two turns. I'm thinking the fact that it's a Minicocker-spec Trilogy body might have something to do with the higher operating pressure?

It's pretty consistent at the moment, around 270fps, but I'll finish tweaking at the field the next time I'm there... my little Radarchron is good enough to ballpark stuff but I find the red chronies are better at reading consistently.

I also swapped out the u-cup seal for a 009-70 buna, seems to have resolved my intermittent barrel leak. (Or it's a coincidence.)

Keep in mind the nut driver can’t have an OD larger than .6875(ish)… I bought 3 nut drivers from Lowe’s/Home Depot and all of them were .75 OD (stupid blister packs prevent you from being able to measure).. I ended up just turning down the OD on my lathe

Jay, the Nova guys suggest using a nut driver instead of a socket since they usually have thinner walls and can more easily fit into the hole in cocker bodies.

Is there a special tool used to install the Nova valve? I was at ION this past weekend and the guy at the NFG tent said he didn't have the right tool to insert the Nova valve that I bought.. in addition to that, the guys at the Nova tent said they could not install the valve I just bought from them because my current hammer inside my 2K had a divot and they suggested I buy a flat-faced hammer instead.

What happened with the Laz? I didn’t make it out to the field.. kiddo decided to wake up at 1am and cry incessantly for no apparent reason…. I was “le tired”

Ran my Nova valved Sniper today and it was perfect. My Lazarus valve not so much. Going to have to do more tinkering with it as it was useless today.

[Frmrspec]

How are you measuring the pressure? Hopefully not the gauge that comes on the snipers because those are terribly inaccurate..

[Frmrspec]

I built a 2K with Nova valve, a sniper with morph valve and a sniper with laz valve just to compare them all.. hopefully will get some film tomorrow..

Both me and my friend have them in our empire snipers, Jenny hammers and springs. They are both at 150psi. To me it sounds like yall are not able to get most other cockers down that low?

[latches109]

increasing pressure definitely increases velocity. I choose to try and hit 190-210psi because I like the sound and how it shoots. If you are trying to max out the lightness in the hammer spring, or lowest LPR pressure, then dancing with both pressure and IVG tension will be needed.

[Psycho91]

I have been wondering this myself, so with the laz valve you just kinda pick a pressure to set the reg at and then adjust with the ivg and then tune from there

[latches109]

no sweet spotting in the traditional sense. All of the 14 Laz valves I have installed so far sat around 180-240 PSI depending on body, hammer, spring etc. Try to hit 190-210 PSI, seems to be the correct pressure for the stock valve spring.

My mistake.
