If you rotated the wheels by 90 degrees so they remain flush against the body, you might be able to make a really powerful bow that meaures incredibly thin on width. I imagine this would make it more mobile and easier to carry, especially around corners and low arches. I know folding limbs exist on a crossbow, and crossbows are meant for hunting so you'll typically be out in the woods and not in either of those 2 situations very often, but the idea of a long and skinny crossbow seems pretty novel to me.

I don't know if you are aware, but what you've built is basically a crossbow version of a type of speargun called a "roller gun". They are by no means a new invention, I think the first one came around in the '60s but for some reason, they disappeared until maybe 10 years ago or so, and by far most of the ones I saw back in the days before I started building my own, were homemade guns. These days they are manufactured by a couple of companies I think, or you can get drop-in kits to modify your _(some)_ traditional speargun(s), to a roller. One of the problems with traditional spearguns is that they don't use the full length of the stock, they generally only transfer energy to the spear over some 2/3s of the full length, and when they do they go from transferring 100% of the energy to 0%, meaning that the energy curve is rapidly declining. Then you can add another set of bands, and that _does_ give you a decent amount of extra energy, but it _also_ increases the already rather substantial recoil. Roller guns however, never let the bands contract to 0%, because the bands are either pre-stretched or as in the case of my first gun, also boosted after loading with 2 sets of booster bands. So, energy transference-wise, they go from some 150% or more down to maybe 50% at the point of release, I haven't done the exact math on it, but it's in the ballpark. As for recoil, I'd say a roller only has about 60% the recoil of a similar length traditional speargun. I would recommend you look into this type of speargun, clearly you are a skilled craftsman, so it shouldn't be too hard for someone like you to adapt a speargun roller system to suit your needs, or at the very least reuse the technology for something besides hunting fish underwater. I reckon you could easily shave those wheels down to around 35-40mm in diameter, and thus get a much sleeker result, on a roller gun the wheels are upright, the pull comes from the underside as the spear is pulled by the "wishbone" on the upper side of the wheels. On a roller gun we need a couple of string risers at the end of the stock because our spears aren't pulled from the end, but from a groove or "shark fin" located a bit up from the back end of the shaft, where it goes into the trigger system, but you won't have to worry about that. Most traditional spearguns around my part of the world are either what we call "75'ers" or "90's" as that's the band pull measured in cm, the shorter ones are primarily for hunting around structures, whereas the longer ones are better for open water. My main gun is a bit shorter than a "75", but shoots like a "110", so there is a lot of length to be saved with a roller gun design. One of the greatest features, in my mind at least, is that you can add several boosters without increasing recoil significantly. Anyway, if you decide to have a go at new crossbow, feel free to ask anything, I've built a bit of this and a bit of that over the years, and I might be able to answer some of your questions.

Three obvious things that can improve the system: use eccentric cams to let off the spring force - this will even the force and make steady the acceleration curve, promises up to 50% improvement when balanced correctly to the weight of the bolt; do not use extra passive rollers - I recon you lose up to 20% of energy in them just for the sake of springs moving in parallel to the stock; synchronize the string pulleys, 20-30% of energy loss here, the easiest is to use one spring and distribute it into two cams. With all of those you may practically double the energy. Further, the bolt weight must balance with the weight of the spring, roughly it should be equal to the weight of the spring divided by two roller ratios (because only half of the spring moves "on average"). You may improve the system even more by using an air spring, e.g. from the spear gun using a carbon fiber drive rod.
@aurigo_tech

Good points! Most of which I was aware already. Some things are hard to combine though in one device. For instance to have one large spring but also no rollers to redirect the string - I can't really see how that would be possible without adding new components which increase drag/losses again. According to my calculations this crossbow converts just under half of the energy stored in the springs into kinetic Energy of a bolt. And yes I am sure I can increase that ratio. I will add non-circular cams next, as well as remove friction losses like the redirectional rollers and some other mentioned things, like improved adjustability. Thanks for watching and giving an excellent analysis!

@@aurigo_tech Glad that we are thinking in cohort! A single spring can pull a Y-shaped wire distributing force directly to the cams, synchronizing them at the same time.

Another interesting direction of thought is torsion springs - those are the most energy-rich ones with he least amount of "attached mass" (carbon fiber, possibly?). They work exceptionally well in high-ratio pulley schemas.

Replace your coil springs with high grade nylon monofilament, extending right back in grooves to the back of the stock. It has over 140% original length yield strength and the highest energy storage per weight in tension of any common material. Run it directly to wind up spools directly on your throw wheels. If you offset the centre of rotation on the throw wheels and reduce friction by having them offset forward and unwind the throwstring directly at their rear, and preload the nylon tension cords, then you can easily achieve a constant force and acceleration over the whole throw of the Arrow. Then you will have a world leading crossbow in power and accuracy.

I was thinking that if you designed it carefully, the gas spring could give a much flatter draw curve. A mechanical spring is a Force proportional to stretch so the thrust force on the bolt drops away as it moves out of the bow. But with a gas spring that wouldn't necessarily be so, you could potentially have the same thrust on the bolt for the entire stroke or close to it. Also being able to dial in just how much thrust you want to give to the bolt seems like a plus too. I don't know how to do this, I do electrical stuff, but I 'd love to be able to build something like this.

You can thead a hole in the middle of the bolt holding the springs and then put a threaded rod through it, in the middle of the stock. Fix the rod at both ends, attach something to turn it (like a knurled wheel or an attached ratchet wrench) and cut some slots for the spring holding bolt to move back and forth. Now draw weight would be adjustable while the draw lenght stays the same. Lots of added complexity but you could also use it to load the bow by adjusting it down to hand draw levels and then ratcheting it up all the way back up again.

But again I have no experience with these and would need to look closer into it. Unfortunately he has no shot over a chrony as far as I can tell, so its hard to judge the true power of these (especially considering that zylinder is huge - compared to the relatively small springs I have).

Well the earliest spring projectile discovered was a bow an arrow 65,000 years ago. Not surprised why it didnt take off. But it is a cool concept nontheless.

Gut Gut, very nice German engineering! I like this concept and the idea of using cam-like wheels but only in combination with bearings. If you want to get higher with de energy you fore sure need a better string, the one you use looks like some sort of normal braided cord (correct me if I´m wrong) A professional string is made out of material with low expansion what means that more energy is transferred to the arrow. Mach weiter so!

Jo, dankeschön! Seit dem Video habe ich alle sehnen gegen richtige Bogensehnen ausgetauscht. Das hat zwar die Energie nicht merklich erhöht, aber die Konstanz der Schüsse, da bei den Seilen die Spannung an den Federn nach ner weile nachgelassen hat. Ich bleibe auf jeden Fall dabei und entwickle es noch weiter.

I wonder if you and Joerg Sprave could do a collab and make this a repeating crossbow... 🤔

All crossbows are spring powered, it's just that most use leaf springs rather than coil springs.....

I always thought the Gorons in Breath of The Wild needed a ranged weapon. This would be a great design for them
