Semi
I’ve found myself investing a significant amount of time and effort on turning the condor into a semi auto, eat all comers, beast.
So I’m now wondering…
Is it just me?
I’ve got 1:1 a plastic (laser cut acrylic) proto going for the feed mechanism, and a working concept for an e-valve that can handle the rpm.
Costs are redonculous, between valves, machined parts, and ic’s I’m looking at more than 400 bucks in parts alone.
As you all know, I’m a noob in many fields.
I guess my question is : Is there any interest, or is it just me?
If there is, I’d love to show you guys the semi proto, perhaps get some feedback?
( I saw the last guy that showed up with a semi concept…I’d rather not go that route.)

Cool project! I’m really enjoying watching the saga unfold.
You mentioned that heavier pellets won’t help. There may be some advantage to heavier ones since they will take longer to accelerate giving the valve more time to dump air into the breach. Just a thought.
The EuJin 32.4 gr pellets are so tight in my condor .22 that I have to force them in with my thumb. Same with the 28.5 grainers. I don’t have a chrony but they are so slow out of my 12″ barrel that I can watch them through my scope hit the target including the 3″ drop from about 25 yards out to 40 yards where my target is.
So the valve takes 30ms to open fully, but once it does, you can drop psi like no one else. This was causing problems, because by the time valve got wide open, the pellet was already out of the barrel.
The trick is then to delay the air by 20ms or so. What you have then is a glorious 10ms window where the pellet is literally shot out of cannon, instead of 30ms of acceleration.
What I have going is a combination regulator/bolt slide that holds the pressure until its at its max, and only then releases air into the chamber.
Ok last I read was u where trying to get the flow rates high enough, how is that going
Good. Solved the problems by integrating a qev into the action. Need to get myself a lathe to get it where it needs to be though.
Lol how’s the solenoid valve going?
Nothing much more than that really, some white plastic bits maybe?
Ok looks like a mag and yellow plastic, what do we have here?
Yes. 😉
Any more work on this mod?
I was doing some mulling over the experiments this weekend and realized that the Condor valve has more power than this air operated thing I’ve got going.
I can dump lots of air at will, but I can’t dump as much air as the stock condor valve for the first 3 or so miliseconds.
23gr pellet, Condor Valve, right through a 2×4.
23gr pellet, my valve, stuck about 3/4 of the way.
I don’t see how going with a bigger, heavier pellet would help me, now that I think about it.
This is plenty to get me going with the semi-auto mechanism though, that’s coming up.
Money, check your PMs.
TOTW-
\
track of the wolf barrel liners.
if you cant part with her, ill probably be able to afford 1 in the next couple of months.
I wish I had a larger caliber barrel, or some way try and sling arrows with this….What’s a TOTW? Any ideas on the cheapest way to go big bore for testing purposes?
750 psi drop per shot sounds like it could push some lead around, , but I just cant gain access to it with my .22 barrel and super lightweight pellets.
It also means I’m going to need to get a shoebox. Jesus these side projects can get out of hand.
Money! I have the tri-rail man, I’ll take it back with me too, I just don’t know if I can part with it just yet. I’ll need to reattach it to the gun if I’m going to actually aim this current setup at anything.
That short bit on the front I got so I can mount my harris bipod to the gun. Center of gravity is way too high though, you can’t really leave it unattended, it will tip over almost guaranteed.
BTW…WHERES THE TRIRAIL??? 😆 😆
PS, hows that short section of trirail forward of the fregrip treatin ya?
tellin ya, man.
you should go “air cannon ” on this one , mod the breech, and get a TOTW .60 or .70, or perhaps even shotty slugs!
other than that, maybe restrict flow(post solenoid) to a point where that huge volume can be tamed.

I’m almost to the point where I’ll know if I’ve been wasting my time for the past year or not.
The 120psi my shop compressor deals out is not enough to push a pellet through a barrel, so its time to move on to high pressure testing.
I love working on the the lathe and mill. If my HS had had a machine shop I would have definitely gone down a different path.
This pic is quite revealing, to the point where I might pull it down once the beers wear off. I’m a bit surprised I haven’t heard of anyone else actively working on something like this.
