Structured Barrel Analysis

- Jay Dvorsky, an aeronautical engineer, used a simulation called CEL (Combined Eulerian and Lagrangian) to compare the weight, stiffness, and frequency of a standard barrel to that of a Structured Barrel. This is the world’s first, in-depth analysis performed on any barrel, and these are the results for Structured Barrels:
20% Lighter for the SAME Stiffness
56% Stiffer for the SAME Weight
38% Lighter for the SAME Frequency
Id like to see a comparative analysis of poi shift in standard vs structured as the barrels are heated from shot strings.
I wondered when somebody what Build-A-Bear like this I've been thinking about this 4 a lot of years good job guys
Russian modernised pkm uses this coupled with Lewis style forced air for cooling doesn't it?
Can you do a video on how to go through the order process and what everything means on website
Yes and I plan to release an update making it easier and more streamlined. In the mean time, please see the following and/or feel free to call (833) 822-6647:
Step 1 - Order a blank through us at zero markup (cart item) or send us a blank from your favorite manufacturer
Step 2 - Select your harmonic finishes (cart item)
Step 3 - Determine whether you want us (cart item) or your own gunsmith to do chamber/muzzle thread work
Add each cart item is needed and checkout.
I love watching videos on things I will never be able to afford
Thank you very much for making this video one of my favorite rounds right now is a 6.5 Grendel in the AR 15 platform but I was wondering is there anyway you can show the harmonic vibrations in a video between a regular barrel or an A.R. 15 barrel also floated in on floated barrels compared to your barrel once again with a live action video
is there a published article regarding this analysis? i'm extremely fascinated with it.
Matteo Bizzaro just sent you an email
Seems like the interface with standard bolt action receivers would be a weak point.. Do any companies or individuals make large diameter receivers that match the diameter of these barrels? Would like to see a receiver large enough to allow interface with your barrel threaded without the need for a shoulder.. in other words 1.6" dia barrel threads..
How many shots before groups open up with structured barrel (2x baseline - 0.3 to 0.6 say or something equivalent) - why does that happen according to TACOM? (hint: the 'whip' isn't changing in a proportional manner to explain this effect)
To be clear I completely agree that the design leads to a stiffer barrel. I also agree harmonics can effect trajectory - but to a much smaller degree than is implied. You say to achieve same results would need a 2" dia normal barrel, why not do a head to head of just that? Then you can show how much utility comes directly from the external structuring vs the 8 hole design.
I would love to talk to you guys about designing a Barrel for a air rifle that is in .355 or .356 at mostly subsonic speeds
So if I got this right, cartridges with diferrent V0 shoot into the same hole with structured barrel??
Daniel Wozniak to date we have been able to shoot a wide gambit of calibers with varying weights and velocities and maintain clover groups, noticing a vertical shift and little (if any) horizontal dispersion
I wonder how useful this design would be for scaled down 5.56 and 7.62 machine gun barrels
Lachlan Moore our thoughts exactly. Due to the fact Structured Barrels utilize the negative pressure generated by the bullet passing through the muzzle to pull cool air through the barrel’s breather ports to cool it from the inside-out with its added +300% surface area, we strongly believe this will be ideal for lmgs.
@@tacomhq Still need a QC mechanism though, but less barrel change is still a improvement. And another huge pain in the ass would be the gas system and the gas block...
amazing the fact it is a solid piece. how much the alignment tolerance between the 8 holes?
interesting!! Any idea of Barrel life and cost?
Russell Whitman to date we have not shot out a barrel, and thus far we have noted a vast reduction in throat erosion. We have a few examples on our website with a link to Coastal Precision Consulting’s analysis. Price is $700 for a 20” barrel and $30/inch thereafter (price does not include the barrel). Any barrel can be Structured as long as it meets our OD requirements. More info on our website. Thanks for watching and your commentary
Hey I would love to talk to you about making a custom barrel made specifically for a air rifle.
And would want it to be designed to shoot copper plated slugs in .355 or .356 at probably subsonic speeds
Please email info@tacomHQ.com. Thank you
Don't you mean an FAA DAR? Not a DER? Also, were you able to measure the different mode's frequencies? If so, how?

Hey this is more like it! 👏 Now where can we find the data?
Beach&BoardFan I was eagerly awaiting for your view and response (haha) I am working on posting the data on our website.
I wish all mfg's would implement these levels of science in their marketing, I look forward to your data analysis, and personally testing these barrels. 👍
This looks like the real deal here. Can't wait to test!
@Sick Lee you need data to validate first... unless you're just going to to subjective testing 😏
This is the same idea as a fluted barrel the only difference is that it has internal holes instead of outer grooves. Yes it will make more of a difference because it has more area moment of inertia with that type of cross section. No cantilever beam is harmonically dead so that is just false like I have been seeing people say about these barrels. It's just more expensive because of all the deep hole drilling needed.
Hi Rick, thank you for your comment. I recommend watching Rex Tibor’s th-cam.com/video/1B4takk5pM4/w-d-xo.html, follow this link th-cam.com/video/BaEkVrFJqZg/w-d-xo.html, and or visiting our website and reading how Structured Barrels work for we describe in great detail many physics principles (harmonics, material acceleration, energy, and thermodynamics) at work to achieve a dead barrel, which bears virtually zero similarities to fluting. To achieve zero vibrational frequency - you are correct - requires infinite stiffness, which is obviously impossible. Nevertheless, this phrase was coined not by us, but by the many notable people having shot them. Similar to the question asking, “Are you standing still?” depends on your frame of reference. Customers routinely find loads in as few as 30 rounds with break-in conducting 10-grain ladder tests in 1/2-grain increments and are often at loss for words trying to describe the recoil impulse. Good luck
@@tacomhq lotta words to say "nah-ahhh."
When it comes to Axial compression, why did you go with circles instead of triangles? other than manufacturing efficiency.
I beam is stiffer.
@@silvermediastudio makes perfect sense actually. When you creat a circular I beam, the weakest point being the web gets absolutely no flex while the flanges give it extra strength.
@@Je3perscre3pers yes. and they corners of triangles are stress risers.
@@silvermediastudio i forgot that barrels flex tortionally while a bridge flexes vertically
Pronounced "Oy-larian." The name of the guy is pronounced "Oiler."
Sounds like the perfect job for carbon fiber
M C not exactly. I suggest watching our latest video th-cam.com/video/BaEkVrFJqZg/w-d-xo.html
@@tacomhq so making the exact same barrel out carbon fiber won't be as rigid? I didnt catch that in the new video
What if a barrel was milled down and a sleeve was pressed over it so when it cools it adds tension?
@@____MC____ a "pressed-fit sleeve" would not produce the same results a solid, one-piece, machined barrel does;
i.e. solidly-bonded, one-piece @ the mollecular level.
