- Holy crap! I guess they finally allowed this video, so watch it here or on Rumble...your choice!
This is definitely one of the weirder guns I've reviewed, in case you can't tell by looking at it! This is basically a teaser video since there's a lot more ground to cover with lever-delayed blowback in general, and this gun in particular. Enjoy!
I'm watching before you tube pulls it. They're ridiculous, thank you Mark 👍
That pistol grip got that gangsta lean
It's so wild that one person made that. It's giving me Luty flashbacks.
If Luty lived in rabid Kodiak bear country 😅 but brilliant design .
1:02 The extreme angle on the FG-42 Typ B's grip was to reduce retraining of guys trained on the Kar98k.
+1 Wehrmacht muscle memory from Gew 98 and Karabiner 98k. The German personnel parachute systems tucked, the suspension lines joined into a single riser that attached to the harness near the center of the back, minimal contol or steering. no Fallschirmjaeger would be firing an FG42 during descent.
That handle design is deliberate, it means it can be fired from two positions, either shouldered like a normal rifle, OR also hanging lower on a shoulder strap, "fired from the hip" where the forearm is over the stock.
Mark there is absolutely a market for delayed blowback in 10mm, I hope you are contemplating a production run and make it work, so I have a reason to own a Serbu! glad to see you got the video up finally. Congrats on figuring it and the patience needed to get the video edited!
If you try to find information on such systems you don't want so search "delayed blowback" but "retarded blowback" instead, because a shift in meaning happed over time. For example you will find those systems in Chinn's "The Machine Gun Vol. IV Design Analysis of Automatic Firing Mechanism" on page 54, while delayed blowback can be found at page 42.
I love the full on homebuilt just like that one. Complete it and show it firing.
Downloaded immediately just in case youtube deletes video.
"if you have ever taken a 1919 apart."
No Mark, most of use have not had the pleasure.
Straight out of a French FAMAS assault rifle. Difficult to make it work without computer simulation and CNC-machining. When winging it, one might have some luck, but it would take a lot of incremental shape changes until it works reliably.
@10:10 Mark explaining that infinities are a sign your equations are _wrong._ 😂
The "momentum amplifier" term is probably equivalent to the original term of an "accelerator". In the FAMAS the part responsible for delaying the action is called an "accelerator lever"
Scuffed CoD WaW meta lookin ahh gun. I honestly love it, it looks like a ppsh and a greasegun squeezed out a welded baby. The angle on that grip makes me feel woozy. Also, 10mm lever delay? that thing is a train made of _recoil._ lolol.
10 mm is by far my favourite caliber, not only because I'm European therefore metric lol. Only problem is the price
Where you from ? check in Germany, Czech Republic or Austria. Price are bonkers, really really low
10mm is so awesome!
France, it's really not that bad compared with rifle ammo like .308 (30 to 80-90€ for 20) but still, I get the JHP from PPU/Partizan at 34€/50 and the FMJ from Sellier& Bellot at 38€/50. Honestly it's only 68 cts/bullet but still if you shoot regularly it can become expensive compared to 9x19 from like GECO whose JHP sells at 10€/20
The only problem is the EU......
Bloke on the Range has a video about roller delay ("Roller Locking vs Delay: BotR Addendum") where he describes roller delay as a "down gearing system", re: "momentum amplifier".
Can't stop the signal!
Somewhere I read that the Browning Auto-5, long recoil action, had a "recoil accelerator" a word combo I had never heard before. :) It was a spur cammed with the bolt so when the bolt was going back releasing the barrel to go forward, the spur would kick the bolt back further to guarantee the action spring behind the bolt had enough compression to push it forward.
With pcc's becoming popular surely there's a market for delayed blowback guns that don't cost HK money
Wait, you're saying that someone else has surpassed my ineptitude for welding?
Quick go blind in one eye you can win this! :)
That thing is metal as hell!!
bring back super shorty mark
Im no engineer , but in construction they are the guys who mess stuff up .but gas assisted seems much easier
There is no art to that thing. It is only pure function.
Lé Resistance needs this Barry guy.
First derivative of acceleration is generally called "jerk." It is especially important in camming actions as you say.
Much better than the last one for sure thank you for sharing this enjoyable and informative video with us six stars brother
The original goal of delayed blowback was to minimize manufacturing costs, so how far down the rabbit hole does someone need to go to machine that H peice? My vote is to try his design, if you gas operate it, it would probably be easier to start with a whole new bolt
If anyone doesn’t get to finish it, I watched it on rumble.
Sadly no access to rumble from France 😞
Rumble beats the RUclips bumble
Can I send my wacky designs to Mark? 😂 I use CAD, probably not like a professional, but that’s the same story as my MiG welding!
Thanks for uploading, I always enjoy these types of videos! You’re awesome Mark!
As mechanical advantage goes to infinity, deformation becomes significant leading to an over center mechanism. Hello Vise Grip action.
As a non-math person I am totally lost but still find it fascinating.
I use the Kentucky Ballistics Windage method. I also keep a thumb free just in case.
The system can be also explained by the so called French formula. Its "bolt head mass" + ("bolt carrier mass" squared "mechanical translation" ) = virtual mass
For the Famas it's 140g + ( 240g squared 3 ) equals 2300g
Meaning that that the Famas's real total bolt mass is only 380g, but due to its mechanical translation of 1:3 (for every millimeter of bolt head travel there are 3 millimeters of bolt carrier travel) the virtual mass of the Famas's bolt equal 2,3 kilograms.
thise are the kind of welds that if you saw them on a bbq pit, the meat would be delicious
I would like to see a better lever delayed system but you are the one doing the deeds so have fun and geter done.
Yup,I'm watching it again, this time on YT..
I think the lever delayed action is cool ,but which would give you the best cyclic rate ? Lever delay ?Gas delay ,or blowback? Or does it really matter as long as it's accurate?
It is a work of art.
Keep it up .
God Bless you and your loved ones
That looks like totally awesome that's what it looks like
Lever-delayed, man.
Would be funny it you used a U Channel safety pence post for the barrel shroud and rudimentary sights but left the green coating on it.
Watching now cause RUclips is ridiculous.
Thanks Mark!🎉😊❤
Would be very interested in seeing the bolt more closely
10:10 I believe you could call this an issue with high Jerk (that is, the next derivative after acceleration)...?
no what i think is holy crap, they deleted his video again!
It's so ugly, I love it. I'd buy two.
Juggernaut Tactical has an AR Pistole Grip on that angle to make that AR CA. acceptable.
Looks a lot like Famas...
I think the handle is for cupping, not for completely gripping it.
I'd be curious to compare this to my direct blowback 10mm carbine.
It would be very helpful if you knew how the lever delayed as is failed to work properly. Opening too quickly or not far enough would show you the direction the lever needs to be modified to put it in balance with the recoil forces it's encountering. The 10mm is a pretty high pressure cartridge for such a system which is much easier to make work with a high momentum but low pressure cartridge...ala the 45 ACP.
Thanks for sharing
reminds me of a blish lock but it rotates to make it delay instead of slide and loc.
You've never made a lever delayed gun, either. You can make them a lot simpler than a gas gun once you get everything set up.
The reason the world look like that is because that's an oxyacetylene torch weld also known as Bravsing
Would you want a lever delay system to be harder to push back at first, then get easier toward the end of "unlocking"?
I watched it on rumble yesterday 😮
Lots of poisonous lumber in the toxidendron (posion ivy) group. The danger goes to the guy sanding it.
I've used Chechen (Caribbean origin where most related species reside, not Chechnya), not quite hard as nails, like sugar maple with finer grain, maybe bloodwood is a better working comparison.
It is gone and I'd never buy it again. Dust all over made me clean my shop after and that was hell.
Metal printing has a raw materials bottleneck that is going to be difficult to overcome if a concerted effort is made to stop metal powders and their shipment. Plus the inert atmospheric needs. If noble gases all of a sudden get pulled like a bunch of things in recent years from public access as the dissemination of information increases.
Not so much for classic steels, 0.6% carbon steel would be impossible to stop, what about chromium, molybdenum, vanadium, tungsten, niobium? Then the lesser degassers, deoxidizers and whatnot adding manganese or removing phosphorus? Gets tricky.
For metal construction I'd like a good consumer priced CNC mill. With smart design you don't need the geometric potential of 3D printing for a lot of stuff.
That is awesome... I want 1 or 2 or 3
I love it. I wanna make one
The PPSH × tommygun 10mm is hated by yt
Gas operated, I would be interested to see development.
Is it possible the grip angle was for walling fire?
That thing looks a bit whack but also pretty rad. i like it. ^^
So do you get failed projects from other makers to fix the problems
Yeah im pretty sure that piece is a modified chain link
The one piece almost looks like a chain link
Lever delayed.
My vote is for lever delay
"Accelerator"
momentum amplifier? like a lever?
That ppsh barrelstyle is so 💦💦
I'm going to copyright "momentum amplifier"
and make millions of dollars.
Hey mark, is edwin still alive?
Yes thanks
So.... no barrel?
Was the program Matlab?
This looks like it came out of Rust
I could do that but no. lol not in this lifetime right
it looks like an awful mix of an FG42 and a PPS or something
OOF!
you need to go back to physics class
Favorite yt channel flat out whis I had the funds to have a rf 50 chamberd in a Wacky caliber in like a 577 martini Henry lol
Niiicccceeee!
I like v much

Ripping on Donald Trump as a gun manufacturer but Kamala wants to ban guns. 😂😂😂 good luck mate.
@ihatethegestapo7649 I was laughing WITH President Trump, not at him.
3:06 The question is what will happen, if the bullet get stuck in the barrels throat and the momentum of the bullet equals zero.
