Blodnob valve more numbers and adjusted tophat.
Alright played with the valve again todaymoved the tophat in to 2.4mm still factory hammer spring, 75g hammer, 21g kodiaks, 12″ barrel. Managed to gain another 20fps with a minimal shot spread. I’ll dial in the tophat just abit more in the future and see what happens just.1mm gained me 20fps its the only thing i changed can’t think of anything else to account for the gain in velocity.
01. 868.1
02. 880.1
03. 878.8

20. 851.1 20shot avg.871.5=35.6fpe extreme spread of 38.9fps still under 2 fps per shot π Eun jins next, we’ll see some higher fpes only have 12 left will pst in a bit.

Swallow your soul, swallow your soul!!!
Very evil dead that breed.
Somebody kill that thing, it cant be happy its still alive.
Here’s a pic’ of Baz
Think its one o them dogs from the film “Turner and Hooche”.
“Doggy de bordo” or summet.
Thats rough! π Is that a mastiff, Sharpei? The wrinkles look like a sharpei, but the face what youcan make out looks mastiff.
This just about sums it up. π
Sean.
Many breeds of Dogs out there, what breed might you be? π
Myself it’d be a mutt of some kind, not regal enough to be pure bred π
so what you are trying t tell us in a nutshell is we are all dogs on here!!i already know i am,hahaha
Sean, i’d say the valve performs above that of a modded talon valve. Cygsx doesn’t get that kind of energy from a modded Talon valve. Don’t know what Mike has all done with his valve but its a rare one if it makes that kind of energy. 30-32fpe is about all i can get out of a modded talon valve. So to get 35fpe avg. using a standard hammer spring and a pretty consistent string i think the valve is great. If anything its the 12″ barrel which is hurting me the most. I know i gain some extra air when using the 18″ and the numbers will show that when i drop it in. Its a great valve, like having the high flo, Talon and micro meter all in one.
Here’s my 2 cents.
i started making these valves a few years ago cos i saw what i thaught to be a shortcoming in the origonal design. That problem being ( in my opinion only ) the position of the valve spring. It occured to me that the further the standard valve opened, the more coil bound the spring became. The air has to find a path through the coils of the spring to exit. But as the spring compresses, the path is more and more resticted. So i put the spring on the low pressure side. Problem solved.
Ive tried all sizes of stem ID from 2mm to 13mm. I settled on 4mm (for .22) as that continued the power available from what the standard “moded” valve produced. I dont think any one’s going to get much more than the guys on this forum from the standard layout valve.
Nor from the ones i do, without putting more energy in.
It seems peaple are a bit lothe to put stronger springs in and use heavy ( 100gram +) hammers and use over 190-200 bar.
Newtons 3rd β law. You put more energy in, you get more out. I dont think high fps/ftlbs can be reasonably expected with standard springs and hammers on mine or standard moded valves. If you want to get more out, you have to put more in. It’s physics.
Try a .25 with a 120g hammer , a spring that’ll break yer thumb and run at 300bar ( not recomend) and see what you get from a moded valve n one ov mine.
As for consistancy, well , these guns are dogs. They’re poorly made, unrefined shooting “tools”. And thats why i love em. You are what you shoot kinda thing π . If any of us was really that finiky over QC and constancy we’d all have steyrs or HW’s or summet similair and be griping about the .0001fps spread or somthing really trvial ( have you seen BBS). All any of us are doing is making the best of a bad job. And avin fun in the proccess. At least thats what i do.
Well thats my 2cents worth. Hope it explains why i think my valve is only equal to a moded AF/GP unit but with the ptential for better things.
Atb, and sorry for goin on so long, Sean. π³
sorry again, this should,ve gone on TedQ’s thread. π³ π³ π³
Nice string Bodhisdad and out of a 12″ barrel……………….sweet π
If you can get it to shoot pretty consistent thatΓ’β¬β’s best it would seem. ItΓ’β¬β’s the shootin that counts. Then like you say one can always configure the rifle to what sort of shootin you want to do.
Course in all this the madness continues. π β π

Tuning is the whole rig.
Tell me about it, with Sean’s valve the versatility is endless. I’m out of Jins but am going to install a different valve spring. I’ve had Jins up much higher in the past but with a different configuration valve spring/ hammer spring. Had a 25lb in this week and bent my nice cocking knob π― . i was getting numbers a bit higher but had the tophat out to far (2.8mm) so the spread was off and the hammer spring just to heavy. As you look at the string you can see a up and down pattern, i think with a lighter valve spring behind the tophat will even things out. But with my luck this will throw off the nice shot spread i got π . Ahhhh always trying to improve on what is just fine to begin with. Should just quit wasting time and get that 18″ in. Let the barrel length do the work.
Always figure one is Γ’β¬ΕwastingΓ’β¬

well that Baz is one orrible looking motha trucka,imagine hopping a wall to take a piss and him taking a snap at ya ass,the first one of ole wrinkly looks like my kinda mutt,if i come back as a four leged dog thats who i wana be,hahahaha,nice one sean, π π
