Thanks WOK! I’m going to look over it again and make sure I got it all right 😆 after a couple hours it all looks the same 😆 😆
Got some SWEET groups in yesterday also and found out by accident that holding the gun oh so lightly I was able to shoot a couple groups 3/8″ groups @ 35 yards!!!! woot! normally I’m lucky to get a 7/8″ group…funny last night I read Bod and a couple others mention lightly holding the gun gave them thier best groups 😆 it sure worked for me!
Jim.
Blackops,
That is an awesome post. It must of taken a lot of time to compile. I am going to file it in the reference section.
Thanks
Dang I wish I had that Condor tank 😡 I’m thinking there might be some efficiency gain from using a large valve only opened a little and for a short time… I’ll test that out later.
➡ Do you guys like that charts with notes or all the numbers and notes or both? or neither 😆
Jim.
Hey Bod, they leave the threads short so the set screws don’t crush the threads…my screws tighten onto the flat unthreaded part.
For now I’m using a steel washer that I leave in there.
When I get home I’m going to make new 1 piece valve stems and an assortment of “shims” prolly nylon washers with a little slot cut into it so it “clips” onto the stem and won’t fall off. I’ll tune them to thickness and swap them depending on the exact power I want IE 6’ish fpe for Pigeons in a barn or basement plinking, 12 fpe super quiet suburban hunting or 12 fpe limit field target, 20 fpe regular USFT and normal hunting, ?? fpe no shim when I want max power for some reason?
😆 my back is aching! 2 hours last night and 2 hours today WOOT! very happy I’m getting in my shooting FINALLY! I’ll take the back ache and 😀
Jim.
Jim hows the back today?
Be nice if we could add some threads to the stem as this would make shimming obsolete. I have tried with a hand die, and got a spin around. Felt like i could mess the stem up if i forced it so i stopped. I assume they thread the stem prior to drilling and porting it. Any ideas on this?? I see where your going with this and it would be awesome to have a fully adjustable tophat one in which you could turn it almost all the way down.
What are you using as a shim/s now?
