I completely follow you and have one of your posts on AGN open where you're discussing various reg pressures, wheel settings, and extending the little hammer set screw that contacts the valve.
I think it simply overran the hammer yesterday, too much pressure for the hammer to open the valve with...
"Very little effect only near 5"? So it doesn't do anything until 5 on the PW or only up to 5? Based on what I saw, I'd guess the wheel started working once to 5.
My goal isn't necessarily to tame it down for Premiers. Maybe it was or still is a pipe dream, but I was hoping that I could find a reg pressure with the lighter spring that would give the PW more spread, sending various pellets downrange @ 900fps. Heck, I may have been close before I swapped...
The factory spring, .051", with the reg @ 110 and the 18.13 JSBs were coming out hot 980-1000fps) with the PW on MIN. The shot also sounded really airy and wasteful, but being new to this, it could be wrong. The 25gr JSBs were about spot on, 890ish give or take no matter where the power wheel...
So Tristan over at Atlas Airguns sent me a light hammer spring for my Ghost HP and it arrived this today. A quick change out and I began a new tune. My initial though was, set the PW to MIN and start cranking the Reg up until I can shoot the el Cheapo Crosman Premiers @ 900fps. Then toss the...
Well, that's pretty much exactly how I clocked my Reg side gauge. I was a tiny bit perplexed when I saw the passageway just under the threads knowing o-rings size under the base of the threaded part would probably only obstruct air altogether. Sealing washer less than ¼ turn from bottom out...
How did you "time the gauges"? I ordered a 25mm digital gauge from Huma and figured the right sized o-ring would help me time mine. Once I removed the factory gauge and realized that the air is introduced into the side of the bore just below the threads, I kind of figured that using an o-ring...
I'm a newbie to PCPs but the leak issues I've seen so far with leaks have been the main valve not seating, causing air to come out the barrel. You can put a balloon over the barrel and see if that's where it's escaping, provided you don't know where the air is escaping.
I emptied my Ghost per the instructions to lower the reg and the hammer got stuck in the forward position. It wouldn't cock because of that. Will your gun cock?
Thanks for the links. I ordered the spring kit and set the o-ring kit in one of my "lists". I need to decipher the sizes on the o-rings to see how many of them are useful for my needs. Message me please about the spring you chose to lighten the trigger. I've cranked my 2nd stage weight down...
Do tell more about this o-ring kit and trigger spring. Are they generic parts or specifically for the Ghost? Also, what did they do to help your situation?
I was looking at that Berger Twist rate calculator this weekend and was wondering how good it is for us airgunners. What I seem to recall was it was saying that I needed speeds on pellets for my 17.7 twist rate that exceed the typical known speed limits, in excess of 890, or even 1000fps. Like...
Glad to see you figured it out. Not too pleased knowing that bolts are backing out on their own. I too found my cocking holding bolt backed out this weekend.
