I love how Joerg can look at a relatively high tech product, then make a better one out of wood. :)

[@lapidations]

The product itself (pistol crossbow) isn't high tech at all, only the materials and processes involved in mass producing it. The knowledge and technology required to make a pistol crossbow has been around for centuries.

[@GeraldDowd-ji4vw]

I am right there with your assessment of Joerg, he is by all rights a mechanical genius. He sees something and determines a better way for it to be made. I have been trying to track down the blueprints for the Pump Action Crossbow he made from the Cobra Mini Crossbow, which I own one of and would like to build his improved model. Be well

[@gregobrien6912]

When u say zombies Joerg, do you mean ones like people in your house at night who shouldn't be in there?

[@Crimsonak]

Might seem like a silly idea but maybe it would be more efficient if you made a grip for the pump that was horizontal that you can slide your palm into. Sort of similar in shape to a circular shopping bag grip, but tighter against your hand? That way it's easier (at least in my head imagining it) to keep the crossbow pointed where you want it to be as you pump it. It might also be more stable too.

[@GeraldDowd-ji4vw]

I thought about that very thing but not being able to download the blueprints and build one, I can only speculate on how that might work. Be well

[@awatson22]

Saw the words TUTORIAL. Went nuts. It truly is Christmas.

[@GeraldDowd-ji4vw]

Were you able to download the pdf blueprints? If you have them, put them on the Market Place and I'' buy a set and I'll send you something too. Be well.

[@allentremper8243]

I am wondering if you can make the pull less on the home made version? IDK, maybe a compound bow components? Something like that that will help take much of the pull you need to cock the device. As I am writing this, you just address this issue,but didn't go into any detail on what you think will work best for this action. Thanks for all of you posts, I wish I could come to Germany and shoot around with you. If you are ever in the US, East coast, your welcome at my home anytime. I imagine you are really fun to be around. I love how you take an idea and make it a reality. Great job!!!

[@ragunamist677]

I would love to see a long arm “pump action” crossbow. With a 5-7 bolt hopper. Something more on the practical side for hunting purposes

[@GeraldDowd-ji4vw]

If I am ever able to secure the pdf blueprints for the pump action crossbow, I'll build it as it is specified in the blueprints and then build what my imagination has come up with in heavier limbed bow with a longer slide to accommodate regular crossbow bolts. Be well

This is brilliant, thank you Joerg! Now I want to see a 3D-printed composite version!!

[@mudkip_btw]

J. P. 3D printed bow? Not a chance (if you want something that can be used as a weapon)

[@j.p.9522]

Randy Is there a law against 3-D printing a crossbow frame?

[@Albert-ym9hx]

+J. P. (Prohaska Nation) the bow frame would have little to no elasticity, compared to wood or metal bows. You would have to use some inherently elastic bow string, such as rubber, but even then the plastic couldn't handle as much draw weight as a cheap wood slingshot.

[@PromptedHawk]

No, it's just that the plastic would be lucky to hold for a few shots. Most 3D printer plastics anyway, they're practically pure chinesium.

[@Ty122096]

You think you could add some sort of sturdy arm brace to the cocking lever so your hand is already at the pistol grip when you finish cocking it? You would just open your firing hand and pull down on the foregrip.

[@n8taing612]

You should add a stock to the wooden one so it would be much easier to pull back

[@GeraldDowd-ji4vw]

It always amazes me how great minds work. I have had that same thought the first time I viewed the building tutorial on the Pump Action Crossbow. Getting the pdf blueprints has eluded me thus far but I am ever hopeful that I will attain them and build it to specs. The second one, I'll be adding all the ideas I have come up with. I will take pictures and make blueprints available to anyone that wants to follow my trail. Be well

[@bryansuh1985]

i think it would do better if the lever was with the trigger. that way you dont have to move your hand, nor do you have to do the pump action

[@bryansuh1985]

and add a second pair of arms with cams while you are at it XD. and carbine it XD

[@airforce9872]

that was my thinking as well, just combine the lever mechanism with the grip.

I have watched your videos for a long time and I have been waiting for you to start doing full builds on your channel. Loved the vid!

[@Paronak]

The airgun has more penetration then a 5.56mm bullet. holy shit.

[@acephantom903]

Not quite. It went through a single car door and through some wood. If the car door deformed the bullet (possible) it might not have had enough penetration to go through as much wood because it wouldn't have it in the ideal cross section and probably would be keyholing. A 5.56 nato round has 1700 joules of energy while this launcher has just under 1000 joules.

[@Paronak]

acephantom903 i think the door would we enough to deform the bullet unless it is a green tip.

[@SuperAWaC]

556 is not supposed to have high penetration, the dart is also hugely more massive with a file hard steel tip. it's not really a fair comparison to make.

[@libertyprime1997]

FMJ, which is standard for a nato 5.56 round, would've sliced through that car door and out the back of the shed without any issues, even deformed. You highly underestimate the penetration power behind that round. It slices through standard lightweight kevlar vests easily, and at a distance too. The standard nato 55gr is small and moves at 2700 fps out of a very short barrel of 10.5". Out of the ideal 24" it moves at 3300. This bolt being a very large and slow moving round compared to all modern bullets will by nature have far less penetration power. It probably even penetrates less than a .45 acp. Source for velocity: www.ar15.com/forums/t_3_118/511787_.html&page=1

[@SuperAWaC]

LIBERTY PRIME i don't disagree however the thing about 556 is once it hits something it starts to tumble because it is so light

[@trod146]

paul pritchard lol he actually made a slingshot for taking down dragons. It's super badass

[@CarespankerGuildslayer]

I have a question, why didn't you make it so the trigger end is also the string pull back handle? isnt it a little awkward for you to press your hands together to pull the string back? if you had the trigger pull the string back (almost like a bow or slingshot motion) and have the pistol grip slide up from a slot on the bottom with a hook attached to it(that would slide underneath the string and grab it once it passes). I feel as though it would get you quicker results than the second version.

Out of curiosity could you increase the barrel lengths along with the arrow lengths to increase the arrow velocities for your air guns, or do you already have the lengths pretty well optimized for practicalities sake?

adding a shoulder stock might reduce the required force needed to charge the handle but this is exactly what i have been fantasizing for

[@shanek6582]

To make sure both the point and knock end of the arrow have fallen perfectly into battery before firing, you could make a simple electrical circuit that makes an LED light come on in the rear. You could just have the two contact points in the arrow tract, point and rear, and the aluminum arrow would complete the circuit when it falls right.

[@justinwiggins1856]

i like this guy. very calming to listen to.

[@ryanmobbs344]

is there not a way you can spring mount the slide rather than using elastic bands? like for example have a hinged piece of wood that lifts out with springs facing down to put pressure on the slide?

[@Drosera420]

I almost wonder if something closer to a shotguns forestock would work better for resetting the bow string. The grip you've got there seems like it would be leveraging at an angle which would generate a lot of extra friction making it harder, thus slowing you down.

[@alfyr.e.meyerakaa.r.e.m.4434]

I learned a valuable lesson today when testing out my replicated Jorg-Ko-Nu...wooden triggers, even plywood wooden triggers are not recommended for crossbows of any poundage. My left thumb took the brunt of the strings snap back. Ouch. Now I'm fabricating a metal one. Here's hoping lol. I have rigged a 'safety' on my pistol crossbow for those just in case moments.

[@johnrisher3007]

you never use crossbow wax to lubricate the strings and rails?

[@Slingshotchannel]

String can be waxed, but the rail is polished to high shine and does not need any wax.

To increase the speed of the valve you could introduce a piece of string with slack in it so the rubber acting on the valve is moving at full speed by the time it starts of opening the valve.

@jeorgsprave wouldn't it b more convenient if u attached a rubber band to the pump action and front part of the bow to send it forward without having to push it forward it's small detail was just thinking might b more fun. but then again I'm more use to semi auto firearms. great job on the build
