The way theis threats his brand new actions...you want that man to raise children!!!

 

[THEIS]

Hi,

So while we are busy running all different FEA simulations....
Here is the receiver body with 145k PSI (Real pressure, not cartridge pressure) put on it as a single plane static model stress.
The deformation is an exaggeration of the software. Scale is in top left corner.

Sincerely,
Theis

 

[brianf]

Pretty slick graphic.

Never saw a mfg post something like that before.

Actively hitting refresh for more!!!

 

[THEIS]

Hi,

We suggest that nobody let anything much larger than an M1 Abrams run over their Hoplite Arms bolt, lolol

Here is the bolt with 145k PSI (Real pressure, not cartridge pressure) put on the entire front area as a single plane static model stress.
The deformation is an exaggeration of the software. Scale is in top left corner.

Isn’t that the definition of bulletproof?!

You're ruining all my T&E ideas here

 

[LeftyJason]

@THEIS not understanding FEA what color would represent going out of the elastic deformation range? Or even better what colors correspond with different points on the tensile strain graph for the material? (can't remember what that thing is called).

 

[Sticks]

If I ever see a receiver in person that streched out oafter a shot, I might pee myself a little. I got that it was exaggerated, but daaaaaaammmmmnn

 

[brianf]

If I remember single plane static stress transposed to a rifle rifle action would be like taking shaft the size of the bolt face (I’m guessing this is a regular short action sized bolt face 308 win) and pressing 145000psi strait down its throat.

On one linear direction, no expansion

So quick math .473” bolt face has about .178 square inches of surface area.

.178 x 145000 = 25800 pounds of force more or less.

So pretty much it looks like the bolt and receiver can handle a SHIT ton of pressure and still not fail (i don’t see any deep red colors which would usually mean material failure) or in a action catastrophic events.

Since this is a static model and doesn’t seem to have any dynamic stress or “shock” like a rifle action would when firing.

With all the dark blue throughout it pretty much means the action laughed at it.

Only stress points at the bolt lugs and even they look to not permanently deform (again if I remember the color scales). Which I would expect because they take the brunt of the reward force.

That’s ridiculously strong.

Pile up a couple of pick up trucks on a 1/2” shaft ...balance that on the bolt face and this action laughs at it.

Hi,

So we are running and running and running some more, lolol....

The below bolt pic is from running predicted cartridge pressure of 10k bar (145,037psi).

How's it feel when your creation laughs at you Theis?? It's currently saying, "That's all you got, gimme more!!" Awesome to see it holding up so well

 

[brianf]

I’m guessing..

Gray is almost untouched / way below max

Blue/green is showing up on the scale

Orange/ red would be getting up there (I don’t see any)

Looks like the last set, those pressures aren’t even waking it up from its nap.

Correct me if I read the scale wrong.

Hi,

Thanks!!
Luckily (or unlucky, depending on how you view it, lol) for us there is not a cartridge case that can function at 145k pressures; so for right now that pressure is off limits in regards to operating pressures, hahahaha....not to mention you damn sure do not want that recoil very much.

Pretty much and now for something we do not hardly ever see in the firearms industry......a company showing the "Red", lol
Here is the Kopis Bolt Stress Plot at 10k bar cartridge pressures. The red areas are above 200KSI from such cartridge pressures.

With that kind of ceiling it should run those 80-90k high pressure cartridges no problem, the conventional chamberings would barely be a warm up. Very well done

 

[want2learn]

fascinating......would gentle curves or chamfers rather than sharp edges at the interface of lug to bolt or receiver prove more forgiving?

 

[357Max]

Hi,

That receiver is one of the original birdsong coated ones.
If anyone cares to throw up videos of DLC'd receiver please do. I am really am interested to see what it holds up to.

Sincerely,
Theis

@THEIS - As I'm sure you are aware, not all DLC is created equal. There are differing application processes that can produce very different results.
For automotive racing applications only the best will live on wrist pins, valves, cams etc.

Might want to check with Industrial Hard Carbon in NC.

They were early adopters of DLC and pioneered DLC application to some of the most challenging racing parts. I can personally vouch for their quality DLC work. My experience pre dates DLC's use in firearms, but I've been to their plant in NC back when they used to call themselves Extremion.
A large percentage of Wrist pins, valves, flat tappet/billet cams, and lifters used in Nascar and NHRA were done by them back in 2007-2010 when I was last involved. It's pretty amazing to see a side by side comparison of a DLC wrist pin next to an uncoated & larger pin from a Cup car after 500 miles + with minimal oiling due to high vac dry sump. DLC looked brand new. Uncoated & larger O.D. pin galled to holly hell.
I've seen it first hand in cup shops and in Marine race engines I built after 500 plus supercharged hrs.

Firearms Suppliers: Increase RIO by Coating in DLC - Industrial Hard Carbon
When it comes to firearms, suppliers are missing an opportunity to generate ROI by coating firearms in diamond-like carbon coating. In a nutshell, by coating parts of a gun in DLC, dealers are able to guarantee a longer lifespan and less maintenance on the firearm. This then allows the firearm...

For an even more cutting edge coating baliq-carbos from Balzers is worth a look.

Oerlikon Balzers unveils latest innovation: BALIQ CARBOS - beyond Diamond-Like-Carbon (DLC)

Hi,

@357Max
Do you have a POC for Oerlikon Balzers? I emailed them this past week to see if any of their USA locations were capable of processing firearm parts with the Barliq Carbos but have not heard back.

Hi,

Advance Notice of OT kind of post, lol...

Just wanted to say Congrats to my friends and colleagues over a FireFly Aerospace on their DARPA program.
Now if we can just Mr. Rocketman to finish up the internal dimension specifications of a few cartridge designs to increase the ignition/combustion/burn process I will be even more excited for FireFly, haha.

Soft goods.......
Sounds like I need to get some shirts with serial numbers to match rifles and include in the purchase.

[THEIS]

Hi,

OK guys and gal, lol...

I want to take a minute to Thank and Congratulate a few more friends and Hoplite Arms family members.

I also want to take this time to introduce you all to someone that will be part of the customer journey and business brand you sometimes read me talking about.

So without further delay...

Please welcome @Jamie C to this thread, the forum and the industry in general.
She is the newly appointed (since we did not have any until her) Social Media Manager for Hoplite Arms. She handles all the business branding of the social media accounts and customer interactions on instagram and facebook right now. I will be transitioning her to SH slowly but I will be here too.

So this past weekend her and her husband attended and took part of the Spearpoint Ranch ELR match and it was a great time to see how she liked the ELR side of shooting since IIRC she had never shot past 300-600yds.
Long story short.....she made it onto the 2203yd target and liked ELR so much that she told me she was going to need a bigger gun, lolol.

Congrats on your 2203yd accomplishment and THANK YOU for taking on the social media roles.

Also Thanks to @Geno C. for talking his wife into this side of the industry for me along with that crazy long drive to show how what ELR comp was like.

Sincerely,
Theis

 

[Jamie C]

Thank you @THEIS! I’ve been with @Geno C. (I hope I tagged the right Geno C) for 20 years and have been very much behind the scenes. I have attend many shoots as a spectator, and the last few years have participated. My good friend @northern50 borrowed me his 300 Norma and loaded ammo for me. I was “bullied” into shooting this weekend (thank you @duramaxman08 ). I’m so happy that they did. I had a blast! I’m hooked ❤ I’m so excited for this opportunity, and yes, I’m excited for a larger rifle

Hell yeah @Jamie C
Teach that husband of yours how to shoot. We all know he needs help!

Sorry for late reply. For some reason I'm not getting notifications for this thread?
I do not have a POC for Oerlikon Balzers. I worked with Industrial Hard Carbon in NC when they were called Extremion. At that time they did a lot of the the coating for the top Cup teams & NHRA pro stock. Coating was top shelf for sure. There was a lot of emphasis on cleanlyness of parts to be coated, they had a special cleaning procedure that left zero residue prior to coating. It was White glove lab level. I never saw a coating failure on valves, lash caps, wrist pins etc. & those parts get hammered literally!

I want one of these with the KMW Sentinel even though I cannot justify a bolt gun. The sheer quality of this product, design, and overall durability (though unfielded) writes its own justification.

A standard Rmag without SCIF certification would probably be a shit ton cheaper. But I'm just guessing. Haven't priced-shopped TSCIFs on eBay lately..

In my case I find it annoying every time I have to do something on a mobile style device, productivity is so much less and forget about decent multi tasking.
Even something as simple as chats / texting / group chats, I can do so much faster with an actual PC.

Just as an informational note, Gordon's Reloading Tool has a Linux version available for download.
I tested it on Linux Mint 20 x64 Cinnamon edition & it works fine, you just need to make sure to read the manual where it has the install instructions and do the whole long string of sudo commands and then it works.

Hi,

Breech cylinder and bolt FEA at 145k cartridge pressure.

That is good safety margin for the insurance company while operating at 80-85k cartridge pressures.

Sincerely,
Theis

 

[357Max]

So how does that work for insurance?
I'd assume they require actual proof firings in a test barrel to validate FEA predictions. Do they hire 3rd party engineering consultant to evaluate FEA and test data?

Please for our entertainment, fire a solid over a crono when you do your destructive proof loads

So it looks like 256,250 psi. Is that the failure threshold? If so, 3 x safety margin over 85K, assuming FEA pressure closley correlates to actual chamber pressure.
