In my opinion putting the O-ring at the base of the thread would mean the entire cavity that the barrel screws into would have to be air tight. In some of my home brewed stuff I have used a captured O-ring inside the baster where the barrel meets the breach. When the barrel is inserted carefully the O-ring stretches around the seam.
While not quite as quick to remove, or tool-less, I wouldn't mind seeing more like that, I think some sort of standardization could be interesting in terms making blaster modding more accessible to people as well.
spectre does threading for all his HPA stuff, I've talked to him and he said he was waiting for someone to design the caliburn/TC part for barrels to thread into. And I almost convinced him to design the part himself, also I don't think the O-ring would even be necessary at all.
That is a valid question. It should be possible to use O-rings to get a seal with threaded barrels. I think one reason it isn't commonplace is the extra work/processing it would take. It would be possible to do it with hand tools (plumbers did for ages) without having to buy machinery. Although, even the hand tools can be a little pricey. If some of the more mechanically minded people tackle it, we could get there. I'm looking at you Slug, Silverfox Ryan, Hawki, and Roboman (and many others).
It would probably have to be implemented into the design of the barrel. Make it have thicker walls. Then, with a short smooth section after the threading followed by a lip thanks to the thicker barrel walls, the O-ring would get squished between the breach block/chamber/whatever and said lip, creating a seal.

The cost aspect was definitely one of my concerns, and I was wondering about thickness of barrels as well if they needed to be changed to accommodate the extra space for the o-ring, and that throws off compatibility with a lot of things, so it would require a large shift from a good portion of players to see success, but interesting to think about.
@@Jangular another option would be to have the o-ring in the female part of the threading and have the face of the barrel press against it. though i don't know if it would then interfere with the darts
I personally added threading on one of my old PAB 2.0s so it could use threaded monkeymods barrels and it worked perfectly fine cause the pusher sealed with the barrel not the trunnion piece the barrel threaded into. And I'm horrible at CAD.
You might be able to use a Nylock but for the barrel to thread into. That should give it an air seal. The nuts could be trimmed and embedded into a 3D prints. You can tap N thread anything so it's just finding the right materials.ThankQ.TkEZ>UK
I believe the part you couldn't remember the name of is the Trunion. The part where the barrel threads into the receiver. I do mechanical design for a living and ive thought up a super nifty quick change system that could be implemented on blasters. I dont think we've seen threaded barrels become more normalized is for a few reasons. One, I dont believe most designers in the hobby have experience with firearm mechanics (I do). Two, threaded components can be costly to manufacture and require specific tooling, especially to do it correctly. Three, maintaining concentricity with threaded components can be tricky. This is very important with firearms, but not so critical on foam blasters.
I was actually wondering about this recently. Ive had barrels come loose on my Talon Claw and Caliburn in the middle of a game due to the screw coming undone or the printed part itself having given out and cracked where the screw sits. If you were able to screw in the barrel it would eliminate the need for the set screws and prevent stuff like that happening. And also having the option to change your barrel length on the fly like its nothing would make things so much easier between rounds.
@@Jangular oh definitely. I just installed a 35cm Monkee Mods barrel into my Talon Claw with the Jet Threading. Would be nice if it would be able to be screwed in instead of friction fit. Also what was that SCAR barrel you took off the longshot?
I agree that would be great. I like my omega kit and thats one of the reason.Yes you can use an o-ring on my Nexus pro worker internal kit has one on the threaded pusher. Check out Bradley Phillips review on it.
It's absolutely possible to get good seals with a threaded barrel. It's interesting-- I think with a weekend in CAD it'd be totally possible to design a smart sealing system.
For the questions at 4:20 I don't think you'd need two o-rings because the pusher should be sealing directly into the barrel so it wouldn't matter if air escapes through the threading because it shouldn't be there anyway.
I was thinking about the fact that there's already o-rings in other places to seal, but just wasn't sure how much air would escape through the threading potentially and what kind of variance that could add.
The only stupid questions are the ones that aren’t asked. You have a good idea and I agree that this kind of barrel system would be pretty useful. Maybe a little hard to make but probably can be done
I think the largest issue with the threaded barrels is adding a good interface with the beech and pusher, which needs to be higher tolerance, or we get issues like FPS fluctuation in the DartZone pro series. Threaded barrels are theoretically ideal but expensive, and this hobby is cheap. You would need a new breach piece that interfaces with the pusher like in the jet blasters and than mount that in xyz blaster, which can be a bit bulkier. Ultimately it’s been a more cost saving measure, as jet barrels are 10$+ where as other non threaded variants can be way cheaper and our systems are good enough that a lot of people aren’t willing to invest into it, yet at least. O ring on the end of a barrel thread is definitely a better way to seal and I believe modern jet offerings come with them You can hot swap your caliburn barrel with the barrel retention screw up currently if you wish though,
Cost was one of the major things that came to my mind as well, guessing it would take more bulk providers offering barrels and interface options that worked at affordable prices to really stick.
Personally i dont like threaded barrels on springers. On HPA blasters its fine with a SUPER core cause it uses a brass "guide" where a barrel can be threaded in. although my designed blasters i keep in mind to make stuff "easy to maintain" which includes barrel material. If im correct the lynx uses a oring on the inside to give the barrel a friction fit with a good airseal, but can also be changed with ease
Is there any particular reason you don't like threaded barrels on springers? Is it just that they lack a guide to put them in? Do you feel they're less secure than something like the Lynx?
@@Jangular Sorry, i forget to mention this was for 3d blasters. For those things like the longshot its a good option cause there is a whole shell around those. They are secure and all and its a metal on metal contact. On 3d printed blasters you wont have such guides unless you buy them from aftermarket parts and modify it on your blaster. It takes more time and bring the costs up even higher. Making 3d printed threads can be an option, but they can wear down quicker or if you tighten then even more there is a change you can make a crack in your blaster. Using a O-ring it quite a secure fit and quicker to change if you want to. In some old designs i've used set screws, advantage of that, its super secure, but disadvantage is you need tools for that one (unless you use a thumbscrew) and/or it can damage the barrel if you tighten it to much or scratch the lovely paint. But i think this is a good discussion to let people think for other options ;)
The Nerf HPA community use the jet system. The Supercore comes with a breech piece which is threaded for them. Also worker have there system which isn't as easy to change out but only have to undo two nuts to loosen the muzzle piece and can change barrels. Like I say it's not as easy as the jet system but it's easier than it is to change springs in some blasters..... Also check out Axel custom. Me, Bradly Philips and Psyk have done videos on their scar system 😉...... Also the lynx is an example of a blaster you can just pull out the barrel and change it for another. Need a little tape about to get a proper seal at the o ring at the blaster end though
i kid you not i was days away from asking one of the guys at the machine shop i worked at pre-covid to make something very similar to this if not exactly what you have envisioned 1 o-ring is more than enough to go up to a few 1,000 PSI is implemented properly
Most people optimize their blaster when they build it, negating the need to change barrels or springs during normal use- if you get a jam then you either clear it or switch to your secondary, dismantling your blaster in the middle of a match is just asking to get tagged out. As for the seal question, it would require precision machining of the barrel-breech interface so that the o-ring didn't get smushed when the threaded portion tightened ( you could look at pneumatic/hydraulic fittings to get a good idea ). All in all though, I think it usually isn't worth the reward for putting so much time and effort into engineering what is ultimately a foam dart toy. Only the top ~0.1% of players go that far, it's not worth it for the vast majority who want nerf to be a cheap, fun hobby.
I agree most people do try to optimize their blaster for a certain fps range, my point is, why not give yourself the option of multiple fps ranges with one blaster rather than separate blasters for each? Unless you wanted multiple blasters, which is totally reasonable, I like having multiple, but I also like flexibility within a blaster.
In my opinion putting the O-ring at the base of the thread would mean the entire cavity that the barrel screws into would have to be air tight. In some of my home brewed stuff I have used a captured O-ring inside the baster where the barrel meets the breach. When the barrel is inserted carefully the O-ring stretches around the seam.
Interesting, I hadn't thought of that option, thanks for sharing!
The Lynx uses a push into o-ring barrel swap system and then grub screws to hold it there.
While not quite as quick to remove, or tool-less, I wouldn't mind seeing more like that, I think some sort of standardization could be interesting in terms making blaster modding more accessible to people as well.
@@Jangular my lynx has thumb screws to take out the barrel. You just undo them and pull it out

Definitely have enjoyed seeing the use of threading on his work!

using one o-ring under the threads on the barrel would work, I've seen this used in hydraulic systems going up to over 200bar / 2900psi
Good to know!
I think you'd need an O-ring on the breach side, not the barrel side. Kinda like how Out of Darts' Little Rocket system works
I was thinking one on both, but again I'm no engineer so I'm working with less than complete knowledge lol.
It's absolutely possible to get good seals with a threaded barrel. It's interesting-- I think with a weekend in CAD it'd be totally possible to design a smart sealing system.

For the questions at 4:20 I don't think you'd need two o-rings because the pusher should be sealing directly into the barrel so it wouldn't matter if air escapes through the threading because it shouldn't be there anyway.
The jet system has the pusher seal into the dart gate, in fact the dart itself only enters the barrel by about 2/3 the length.
I was thinking about the fact that there's already o-rings in other places to seal, but just wasn't sure how much air would escape through the threading potentially and what kind of variance that could add.
