.25/.257 Condor Build
Well here is my next build when I have the time. Will be able to switch between .257 and .25 barrels. This Condor will be like no other Condor.
.25 barrel is machined and half the hammer is also. Will machine the .257 barrel next and make a one piece bushing for it. Looking for 200 fpe in .25 and 220 + fpe in .257.

I’m wondering would I have to have a separate hammer knob and breech knob for a .257 build? Is the spring too heavy to have just a breech knob?
awesome build. Wondering if you could build a whole frame as well… :6:
X4 what pablouk said:!:
In fact Pab encouraged me to try what others considered impossible when I decided to convert my 24″.22 high flow Condor to 12″ .177 and tune it down for quiet use in a close neighborhood.
It works so well it is a keeper.
Consider the Girandoni .46 caliber that had a max 800 PSI.

Term “heavy” doesn’t make sense to me.
Imagine a 300g hammer pushed by a MX Shock Absorber…..that hammer cease to be heavy.
So the ideal hammer is the one which control and being controlled by the ideal spring and not the one can’t be controlled by it, resulting an uncontrollable recoil.
….balance is the key!!!….of course that balance depends from the stroke requirement.
Personally i prefer a heavier hammer than a light one with an extremely tight spring….that combination increase triggers pull weight due springs pressure on the sear and accuracy suffered in most cases.
I’ve always maintained that a light and fast hammer gives best results. When Lang and I were making valves and hammers and wot not(well Lang did the making, I helped with the designing) we found that a light hammer travelling fast overcame any little imperfections in the frame (muck or grit etc). It also made for a much faster locktime of course and generally made the gun easier to shoot accurately.
This hammer weight and hammer spring thing confuses me. Is it the amount of momentum (momentum=mass times velocity) of the hammer that hits the valve mechanism or the amount of kinetic energy (KE=one half mass times velocity squared) of the hammer hitting the valve mechanism that counts (goal being consistent yet fast fps)?
What would work better, a light hammer traveling very fast or a heavier hammer traveling slower? Or is it basically a trial and error process to find that optimal hammer weight and spring combo? Last question, is there a optimal spring length (to achieve fast hammer velocity)?
Doug,
I know, we talk pretty much every day or two.
Remember, Jack uses a heavier hammer but he also uses much higher fill pressures than the Condors are used to be filled too.
There is a very strong relationship between the RETURN SPRING, THE HAMMER SPRING and THE HAMMER WEIGHT in AIRFORCE guns especially. A little change goes a mile in these guns.
With the “NEW LOOSENESS” in the hammer to barrel connection, the hammer is slamming forward much faster and with less forward resistance and is hitting the TOP HAT much harder. Just from making the hammer “LOOSER”, I am now pushing 102 gr SPITZERS at 935-940. Were as before, with everything being the same, I was pushing them at 890-895. That’s a hell of a gain just from removing .001-.002″.
I just always felt a heavy hammer created serious spring fatigue. Too me, just the right amount of hammer weight and spring weight provided super fast hammer lock time and still made incredible power.
Let the barrel and pressure make the power and the hammer weight and spring set up provide the consistency.
I would rather see……1000-999-10001-1000-1002-1000-1001-1000-1000-999 vs 1070-1068-1062-1067-1060-1063-1057-1044-down-down-down-….
In my TD257, your set up the way it is is hella consistent for the power that it makes
BUT I GOT YOU ON MAKE THE HAMMER JUST A TAD HEAVIER SO YOU USE LESS PRELOAD. JUST MAKE SURE THE CONSISTENCY IS THERE WHEN DOING SO…….
I have been playing with hammer weight. Trying to find a weight that works good and efficient so less preload can be used. I made this today.
This one started as 157 gr. I got 1082 fps on 3300 psi with 74 gr on 0 PW.
Cut it down to 150 gr and now 0 PW is 1062 fps with 3300 psi. Guns apart right now and I was going to make it 140 gr but I think I’m going to leave it for now.
Doing this because I have 5 hammers on my bench for builds and I’m wondering if 100 gr hammer are enough anymore with what I’m doing and getting out of these guns now. 95-100 seemed the way to go for .25 with condor valve.
Trying to use a little less spring and a little more hammer to see what happens. I took mine a little further just to see.
After seeing that a Haley .257 has 265 gr hammer I got to thinking.
calm down guys…Doug’s not done with his .257 evolution yet.
Cedric, you could quit your day job and become Doug’s apprentice 😀 It would be the right thing to do 😛
Yes for sure. I have the ones you sent me still.
Ohhh trust me Jerry, he will be shooting some Raptors….lol!
Ummmmm, that reminds me, i got more of them to go shoot. Hummm, do i detect another video with them………….?
You’re going to need some Raptors to try with the .452. Ced can make the video so you hear them “screaming” downrange. 😆
Man I like that short LDC. Looks damed good! 😯
Mike
Next is a 32″ .308 with my 1-14 4 groove barrel I had made.
Then a .452 in a condor frame.

Needs to be a side cocker but doesn’t need 2 knobs. 13 lb spring to open valve. I’m running a 150 gr hammer and I get 1062 fps with 0 PW. With PW 2 I get 1082 fps. I might try 11 lb spring and see what happens.
