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.)

W.T.F.? 😯 Is that what a shot out of Frankenstein did to a block of aluminum?
On this thing? No idea, but I’d say in its current setup we’re looking at 6″ over stock tank at least.
As far as prototypes go, this isn’t the ugliest, but its definitely the most ungainly. I don’t think this thing will “shoulder” at all.
If these tests work out though, then the adjustable regulator will get swapped out for a smaller, fixed unit, the couplings will get the minimalist treatment, and I’ll have to figure out a way to pipe everything so that you don’t feel like you’re taking your refrigerator on a hunting trip.
If I end up slinging my .22’s supersonic with this setup I’m going to need some advice on how to proceed with testing.
A.K.A. Go for a larger barrel and slugs, or try to work with heavier .22’s?
(Keeping in mind my budget is fux0red and a chrony is at the bottom of the list. )
dare i ask what your length of pull is? 😯 😯
Lots of new parts are in:
3 way baby solenoid
some air line
pressure reg
air cylinder, 1.5″ throw
cylinder mounting tidbits.
When you guys dry fire your valves, how much of an oomph do you get?
I filled this thing to 1000 psi and fired the thing (just air) , I knocked a few books off a shelf 10 feet away, and boy is it loooouuud.
Now all I need is a fill and a trip upstate to mate this thing with my condor and see what the hell I’ve been spending my time on.
How many are out there? I want them all.
Without the luxury of explosive oxidation there seem to be few ways to release a large amount of energy with a “trivial” input.
Dyotat, would you happen to know much force is required to open your monster valve?
aka, an orifice of 1 square inch requires 3000 lbs of energy to actuate.
yours, of orifice size X, takes a hammer force of X ft/lbs to open.
With that number, I could start figuring out if I could rig a solenoid to impart that force.
Proper obsession gentlemen, requires machine tools.
How much power are you looking for? I have reg set ups that are real consistent. I’m going to try and make a setup that will give me 100 fpe for 30 shots.
my advice would be to tackle each goal 1 ata time, in order of importance.
i do think daves idea to electronically control hammer engagement via solenoid might be a better way to go for now…
I’m looking at all options. From what I can tell, existing e-valve technology is great, but not ready to take on big FPE numbers.
The Rogue was supposed to be it, but apparently the tech isn’t ready for prime time yet.
The goal is pow pow power, reliability and consistency.
you seem to know more about electrons than i can remember, but for what its worth, have you considered some type of step up transformer coil?
perhaps seek out a schematic for one of the more successful electronically actuated valves that arent too complicated, like fx, daystate, etc.
Mechanical actuation of existing valves is definitely an option I’ve considered, not without its own drawbacks though.
Does anyone know about how much force is required to actuate a “serious” valve?
The trick would then be in how to exert control over valve timing. One idea would be to create an “alternate tophat” for existing valves and then bolt-on an electrically driven cam mechanism to activate the valve.
The thing being that at this point you’re counting on batteries producing X joules to activate the valve, which could be quite a pain. Also, the super precise (milliseconds) valve opening control I don’t think would be as reliable/easy to obtain.
Now, I haven’t experimented with the existing poppet valve so I don’t know if it would be possible to make them keep their huge flow while reducing actuation force.
In other words, if a valve with a “hair trigger” were out there, then yeah, lots of ways to do some cool stuff. I think its FX airguns that have a similar system, their valves are actuated directly by a solenoid striker, but im sure they had to tune their custom valve to respond accurately to the usually very weak solenoid “tap”.
Life & Limb: I’m a lot more careful that I let on, I love the vibes on here guys, thanks for caring. The components I use are all rated to well beyond the 1000-2000 psi “desktop testing” pressures I’m currently working with so im not too worried. I will admit that I’m losing a lot of the original “fear” I had about the dangers of high pressure experiments.
Granted, as soon as I start with my own machined parts, and actually try to propel pellets, safety standards will need to reach a new level.
dave,
i like that…
Yep, using oil, wd40 or just plain old diesel will get a satisfying bang, however I highly doubt that results would be consistent and would also have to factor in an exhausting system. But a good idea none the less.
Fairlyinconspicuous – Why not build a solenoid in where the hammer and spring is located that knocks open the standard valve? That would sort your firing mechanism wouldn’t it? I’m sure that there was someone here that was going to do it.

This idea may be way out in orbit, but is there a possibility of (any gun) using controlled dieseling? Poachers in England used to bump up the power of lower performing airguns w/ oil. Of course, it could trash a gun not built for it and you might have a residue issue. Don’t know if specially oiled pellets could add umpf to a lower pressure rig or not.
Had the RWS springer fire a dieseled pellet once, barrel wasn’t swabbed clean enough. That puny silver bear .22 went ripping through the trees.
FI, I think all of us are worried about the pressures you’re involved with; there’s ALWAYS a chance for a defective component. At 6,000+ psi, tripping with the gun might lead to a heart attack, even if it stays together.:shock:
Good luck, many thanks for doing/sharing/experimenting, above all, pleeeeez don’t die or get maimed.

Holy fuck balls of fire i want one eheheh if that did that what speed is that? Fuck.
