DOM Tubing that being used for barrels

[coloradoclyde]

Well, I’m impressed beyond words. Thank you very much. Roundball is right your work deserves a permanent home.

Nice work!
I have to wonder if any barrel with a similar profile would have survived the last test, or even one with a normal load and short started ball.

 

[Alden]

Good stuff! Sounds like fun. I am impressed in all respects.
:wink:

Earlier, you said, " Diesel will seep through and reveal cracks that magnaflux will not...."

Perhaps you meant to say Penetrant, rather than Magnaflux?

Fluorescent Penetrant inspection relies on the fluid penetrating cracks and then glowing under fluorescent light.

Magnaflux relies on the disturbances in the magnetic field flux caused by cracks, non-metalics or rapid grain displacements.

These disturbances are detected by the magnetic particles that fluoresce either applied dry or suspended in a fluid.

Because penetration is not required and the magnetic field is thru the part being tested it can find faults which are not exposed to the surface.

I rate Magnetic Particle inspection to be one of the better non-destructive methods available for steel or iron parts.

Bad phrasing on my part the only way that diesel beats magnaflux is it's hard to get a magnaflux unit into some places. If I had one I would use it, it's cleaner for one thing. Once you test a part with diesel the only way to get a clean repair weld is to dry it out with a torch, then clean it up and reweld. I have Penatratant dye but, I think it wouldn't be as good a choice for this.(didn't know they had the florescent kind)
For the economically challenged out on the farm diesel is a good choice provided you understand it's limits (same applies to any non destructive testing) Any crack on a barrel is a killer, (reweld is just not an option) so diesel is a good choice. Cheap and effective. Thanks for pointing this out.

You're many personal investments and detailed testing were outstanding and professional...nobody else in this thread or on this forum is anywhere near the level of knowledge and skills you've demonstrated with yor actual hands on experience.
:hatsoff:

I hope a future test similar to this one will be done on barrels made from 12L14, so we can put that myth to rest as well.

Just a thought.

And thank you, this was extremely informative.

There have been tons of such tests. But the myth of inferiority won't die.
I recall the tests showed the 'high lead' barrels, when tested to destruction, tended to split and relieve excess pressures through the splits. Other steels, like GBQS, tended to shatter like grenades. (of course, the amount of pressures required for destruction were different)
IMHO, Douglas barrels will still be around when future muzzle loaders will look back at us as being 'authentic' or in that 'back in the day' time.

Lord, wouldn't it be nice if it worked that way?

This myth hasn't been put to rest.

RazorBritches, too much excellent work to gradually fade away...(out of sight/out of mind).
Since you have all your data from which you created your various posts, you might want to assemble it all together in a single stand alone document and send it to Claude to see if he'd add it as a sticky to the top of the smoothbore section...and/or up in the MLF's 'Articles' section.
