This is a full tutorial that teaches you how to make one of these awesome, but expensive airbows at home, from simple parts you can order from amazon.
While the homemade weapon can not come close to the ease of use and super cool design of the great FXAirguns products, it does outperform each and every commercially available crossbow or airbow we have ever seen.
Good luck making your own!

Much appreciate the clear instructions and assembly from off-the-shelf parts. This latter is a real bonus for such as I, who do not possess a metal-turning lathe, milling machine, and machining skills. The design might lend itself to being made, for eminently practical ends, by country folk in lower income countries. An obvious need - to which you, Joerg, allude - is the fitting of a pressure reservoir connected, via a constant-pressure valve, to the air-cylinder ("plenum"). Tod of 'Tod's Workshop' mentions how crossbows were sometimes used during the fighting in Sarajevo because of the greater penetration of their bolts relative to that achieved by assault rifles. Useful when taking out largely concealed snipers. With the aid of an American colleague he demonstrates the truth of this. One problem with bolts and arrows may be the cost of buying them or the time involved in making them. Especially when used in the wild, for hunting, with frequent losses. Have you considered developing a hybrid model,capable of shooting - whichever seemed the more appropriate in the circumstances - either an arrow or a lead slug ? What would be the most suitable calibre to make clean kills on medium-sized game, such as wild pig or deer ? - without unduly wasting that precious substance compressed air. I was thinking maybe something in the range of .30" to .375", or 7.5 to 9 mm. It seems to me that a major problem in re-designing for the use of lead slugs, avoiding machining, could be the making of an air-tight breech for rapid reloading. Muzzle loading would be slow and tedious. And then, how accurate would be a slug fired from a smmoth bore out to, say, 100 metres ? Could one obtain a rifling button able to form the wide, shallow grooves, leaving very narrow lands, suited to airgun barrels ? On special order from China ? Sorry ! Many questions, from a novice trying to learn more. Am not expecting they will all be answered.

If you want to ensure the most stable of wooden pieces, I would suggest you immerse the pieces of wood into a small bowl filled partially with a slow cure resin, and put them through several cycles of vacuum treatment, which will allow the resin to permeate the wood, and then placed in a warm environment to cure. then those pieces of Plywood will be extremely tough.

[@2024WhatNow]

I knew there was a reason I kept the pressure washer wand after the pump catastrophically failed.

[@conmcgrath7502]

I love it but be careful my friend; it depends on the manufacture, I just checked my old 'washer gun'. it is rated at 140 bar maximum, approx 2,000 psi. I don't doubt there are higher rated ones but I would err on the side of caution here? Pax dude.

[@conmcgrath7502]

@@2024WhatNow Be careful mate, the max pressure should be printed on the handle. The spare one I have is rated 140 bar, approx 2000 psi. That's still good enough, for sure but very scary to get it wrong and have a catastrophic failure or an accidental discharge. I love Joerg and I have been thinking along the same lines for a while now regarding air powered weapons. I would add some refinements to the design (as Joerg suggests you might) ; have a reservoir tank, say 250 bar and a pressure limiter that allows (eg) 100 bar into the firing chamber so that you have a constant firing pressure so long as the 'tank' isn't depleted. Now, you DO have to balance the volume of the firing chamber to match the missile/arrow/lead projectile? Too much volume is a waste and it will still be 'blowing' after the missile has fired, too little is quite obvious. As the 'barrels' are so light, I'm considering a multi-barrel version where one small lever rotates, locks, and charges, ready to fire. Pax dude.

[@pfow2006]

awesome idea. have you tried it? does it work as expected? have found some washer triggers dont like to open under high pressures, but they probably weren't rated for the pressure I was using.

[@Karl_Kampfwagen]

@@pfow2006 Most of them are set up so the pump modulates pressure when trigger is depressed (aww, poor guy 😥), and when you press it, the pressure is unleashed, right? Well, then the pump runs at full blast (literally), and the trigger is being flowed through. When the gate is cut down by the trigger being let off, it takes a decent velocity to force it shut under high pressures, I've noticed

[@CEclips]

[@rockyrgs]

Fantastic! You out perform yourself with each new build. I'm fascinated with your talent.

[@MrGsteele]

I built something similar, using a Kidde CO2 Fire Extinguisher. CO2 provides consistent pressure until the last bit. It was actually designed as a spear gun, with solid spears launched from standard copper supply pipe, which fit over the spear. I centered the spear with a standard sliding spear gun collar at front that fit perfectly inside the copper supply pipe, and at the rear with a backing washer, rubber grommet seal that slip-fit the supply pipe, and small washer behind, held in place against a shoulder on the spear (turned down on a lathe) by a castle nut on a short thread I cut at the rear of the spear. At the front end, I threaded for a standard spearhead, in front of the sliding collar. The benefit of surrounding the spear is that the surface area of the inside of the large diameter supply pipe increases the force applied - the psi times the area of the rubber grommet, which seals the air behind the spear (supported by the backing washer bearing against the shoulder of the spear), provided enough launching force to drive the spear through a 2x12 underwater about 12 feet away. It was murder on Striped Bass and other very muscular, large fish - penetrating fully through and opening up the locking wings on the spearhead. To provide neutral buoyancy, I radiator clamped styrofoam on either side of the tank, which made it one-hand controllable, if necessary - although firing at a moving fish was easier using it as a long pistol, swinging by treating the tank as a forestock. Using the Kidde Extinguisher gave me a handle, trigger, valve, and tank - I only had to remove the extinguisher horn and re-attach the tank to the handle through a 90 degree elbow. I then slip-fit the horn attachment stud, screwed to the back of the 1/2" supply line, which I secured to the tank with a radiator clamp. Very compact, very powerful, consistent, accurate etc. I attached a nylon line to the legs of the front collar, looping it through a spring clip at the bottom of the handle and forward to another clip to allow multiple loops, and compressed the line, knotted inside, inside a wired-on gum rubber tube to act as a rubberized shock absorber when the spear reached 15 feet. The waters here are not clear beyond that distance, so you must limit the range or risk hitting another diver beyond your visibility. At the end of a 15 foot run, the spear is still traveling with great momentum, so you need the shock absorber in line to stop it from pulling the gun out of your hand. I also tested it with compressed air, at 3,000 psi (~200 bar); too powerful. For comparison, the 1/2" ID supply pipe with CO2 provided 180 lbs of thrust on the spear; your 250 bar of pressure on your arrow provides 251 lbs; with 3,000 lbs of compressed air in the tank of my spear gun, the force on the spear was 650 lbs - far too much. As it was, with fish like blackfish (Tautog), the spear would go all the way through the fish and hang by the line on the other side. With practice, I found I could modulate the force by pulling the trigger by a greater or lesser amount, depending on the fish I was shooting at, whether there was a rock face behind it or not, etc. Interesting video and skillfully-made garage-built weapon you have there!

[@all8268]

if you see this how much did it cost? and you should upload a video of it

[@MrGsteele]

​@@all8268 Too long ago to quote exact pricing (see below), but the real cost was just the labor - I picked up the Kidde Fire Extinguisher at a flea market, used some copper tubing (supply line) I had hanging around in the cellar, picked up the elbow and fittings at a local hardware store for probably a buck or so. The cost was the spears. The spear head and sliding collar were whatever they cost at the time - I still have 3 assembled spears in the cellar - and what they cost now at a dive store; I used the ones I had for my triple-strand Arbalete. The shafts were hardware store ~3/8" unthreaded rod - steel, not aluminum, for strength and higher sectional density (penetration). The two ends were turned down on a lathe, but that was done at a neighborhood machine shop for a few bucks on his bar stock machine. I cut the threads to match the spearhead thread and castle nut thread with dies from Sears and my hand-held die handle. The castle nuts were standard hardware store items - maybe 10 cents each back then. The rubber grommet seals at the rear of the spear, which could easily be replace with rubber faucet washers because they are backed with metal washers so they don't blow off the shaft from the pressure, were a found item - not sure what their original application was. They are little rubber cups with a hole in the middle, like the rubber cup washers in a single-handle faucet ball. In those days, you'd just roam around in a hardware store and look at things, and get a bright idea. The rest - gum rubber tubing, nylon line, spring clip, radiator clamp, etc. were also standard hardware store items. I'd say the spears (less spearhead) probably cost me a dollar or two each, and the gun certainly less than ten bucks all told, including the can of Rustoleum yellow primer I sprayed it with. I think I paid $5 for the fire extinguisher at the flea market. The shock absorber idea was, I thought, reasonably clever. You feed the nylon line down through an 18" length of gum rubber tubing, pulling a knot you tie in it to within the last inch of the tubing. Wrap wire around the tubing so you can't pull it through. Then stretch the tubing in the other direction over the nylon line almost as far as it will go, and mark the line. Tie another knot at the mark. Then pull the tubing again, until the second knot is an inch inside the tubing, and relax the tubing, which will compress the line inside it. Tie it off with wire like you did the first knot. Attach one end of the line to the gun and the other to the slider on the spear, cutting the line to the right length for the visibility of the water you're hunting in. When the spear reaches the end of its run, the gum rubber tubing acts as a shock absorber, slowing the spear gradually, and stopping it dead, but gently, when the line reaches its limit inside the tubing. If you don't use the shock absorber, the spear wrenches the gun out of your hand; if you don't have the line inside it, the spear can break the tubing, and there goes the spear.

It’s bringing out the machinist in me!

Teflon tape is defunct, as it's far better to use 5 minute fast setting Araldite epoxy resin, which is what the fire department use, on high pressure fittings. Teflon can still leak but when Araldite epoxy resin sets its good for really high pressures over 750 psi. I use it on all my fittings and it's easy to undo just heat joint then resin softens.

In US you have access to a lot of fancy DIY not necessarily available in other places.

[@janred94]

over 750 psi? Not impressive! :D

[@9999plato]

I would use a 1/4" or 9/32" by 1/2" compression fitting and matching tube size to hold the tubing the arrow slides over. The larger size is about 7. 14 mm and might still slide into the bolt shaft. An electrically operated selinoid might be nice too.

I've been watching this dude for a long time now... But it only just occurred to me- just imagine the insane things this Berserker could engineer if he lived here in the States, especially here in the South. ( Where the laws are less Blue) I'd wager he could reinvent the AR platform, and elevate it to a Blade Runner level.. My Father in law is a Kraut engineer. With the things he comes up with just sitting down with a cup of coffee, it's obviously in the blood.

[@worldsgonemad4600]

Hi joerg. Have you tried a home made hammer driven air release valve? While i appreciate the simplicity of a ball valve, and comprehend the differences of pressure build in the bolts body that facilitates its launch i think you could easily add an external compressed air canister and be able to achieve multiple shot capability without pumping every shot. With the hammer valve you could even convert between ball ammo and bolts or have an over under. I'm designing a multi barrel but the air cans don't last long enough. I fire marbles, I need a larger air supply. Portability isn't really there mine is more viable mounted on a fire truck i think.

[@DewaSenapanIndonesia]

[@preacherF-15]

Interesting design! I've built similar airbows, although I opted for machined billet aluminum instead of plywood. Just a personal choice, but it allowed me to float the barrel while at the same time encasing and protecting it. My only criticism would be your trigger/sear/band design. I would make the valve handle much smaller, use a proper steel spring, and make a rotating sear/trigger that can all be covered in a housing and give you an adjustable trigger. Bands break, plus the parts moving in the open can cause injury or be jammed by debris. Just my thoughts. Great job!

[@brertt8350]

he uses crazy strong bands, these wont break, but it is quite a weird system

[@hitbyligtning9661]

itd be awesome if you could upload or have a link to how your design could be built. It sounds like an excellent addition

[@drTERRRORRR]

Awesome vid,man! I have one tip from a friend of mine (a knife maker) regarding the stabilization of the wood (and other porous materials). You need a cheap and small vaccum chamber and the pump. You need to put the part in to stabilizing liquid (Need more details here. I'm guessing the mixture was epoxy-based) in the chamber and start pumping out the air. The negative pressure should pull all the air from the part and it should be replaced with stabilizing agent. The main benefit is getting a material that looks like generic wood,but is hard AF. I think it might also have some uses outside of making weatherproof knife handles? Cheers from PL!

[@swandonovan]

You'd be MUCH better off using a compression fitting to attach the barrel. I've built a few of these that are capable of multiple shots per fill

[@darkswami]

Swan Donovan Do you use a rubber band activated valve, or an electric one? What would be the downside of an electric valve for this?

[@theonetheonlyw5483]

darkswami a power source.

[@darkswami]

A quick search gave me electric valves that work @ 5000 psi: that's about 350 bar. Nothing about the speed they open though. I have no idea about this. they work on 12V so power should not be a problem. Any idea how fast Joergs rubber powered valve opens?

[@swandonovan]

one of the ones he did on the massive airbow opens all the way before the arrow fully leaves the barrel. still not ideal though. when a ball valve is half way open, it's still half way closed. so even though it just fully opens by the time the arrow leaves the barrel, it was at least half way closed a majority of the time. the best valves (read quickest) would be burst disk, and then qev.

i think the back lever kind of looks like a bolt from a bolt action rifle, and that really looks cool.

[@MK-ji5ri]

If got a problem. When I reuse arrows the tips sometimes aint firmly on the arrowstock and fly off when I shoot. Offcourse they are pretty powerfull and work like a bullet. Does this turn the weapon into a bulletshooting weapon wich is illegal in Germany?

[@Slingshotchannel]

No, because that is not the intended way of using them. They will also be weak in comparison because of the very short accel length. Just get some cheap 2mm nails, drill a hole sideways through the shaft and the inlet, then glue in the nail, file flush. Will work like a charm.
