Custom A1 Valve spring

[jpx]

Hey guys, I taught I should post this. I got my Nylon hammer and the valve wouldent open enough to get the FPS to 280 so I opened up one of my Valve stem's, took a pen spring, cut it at the same lenght as the spring in it and put it all up together. Now it RIPS.

Settings are:
Dwell 4
HPR 280ish
LPR 60ish
will get exact settings tomorow

NO KICK!!!!! SUPER FAST!!!!!!!! and shot a bag off 2000psi with air left (improvement compared to before, that was while shooting 313FPS kuz i didnt have my allen keys. So I should get a bit more when I lower it to 280FPS)

Can you take a picture of it? I'm sure everyone would like to see how you did it.

Thanks

How did you re-attach the two halves?

I believe he used crazy super glue or similar.

used super glue, if it doesent hold ill use a stronger glue lol, and for the pics, its just a different spring, looks the same.

exact settings are:

dwell 4
HPR: 280
LPR:65
Got a bag off 2000psi with a bit of air left
NO KICK
Shooting hot so i brought tried this:

dwell 4
HPR:280
LPR 61
Shooting at 280-290
Havent tested how many shots yet
NO KICK

In reference the aforementioned modifications I’ve included a few related images.

Assembled A1 Exhaust Valve: (Lightened spring installed)

The exhaust valve was cleaned and re-assembled with a high strength “gel” type cyanoacrylate; the ram was matched with the nylon hammer and pressures/settings were adjusted accordingly.

The marker is presently configured at 57psi (LPR), 275psi (HPR) and 5mS (Dwell). Additional tuning and subsequent testing is needed, although a reduction in recoil is clearly noted; efficiency will be monitored and recorded very shortly.

Clearly this modification does not compare (or complete) with the reported and subsequently pending high efficiency A1 internals; my goal was simply a reduction in recoil; increases in perceived efficiency would be a bonus, although additional testing is necessary.

In closing, it’s advisable that only those with reasonable air-smith experience perform such modifications as it’s very likely to irreversibly damage your exhaust valve.

Thanks!

Addem: The marker is currently stable at 4.5mS dwell; velocity and subsequent consistency is currently recorded via radar at 280, 280, 277, 281, 282, 280 ...
