Wire coil baffle?

[pmchenry]

I'm just wondering if this has been tried? Seems to me that it would have a similar functional shape to a step cone, only be loads easier to manufacture. Machinery for turning heavy steel wire is cheaper and easier to use than a lathe/mill setup. Hell, I'm no machinist and even I have used such equipment in previous manufacturing jobs I've had. Think something along the lines of the following product, only without the hook and to the proper dimensions required for a baffle of course:

If you spread the coil shaped cone out you may in-cress the turbulence between turns and the skeletal cone may still strip gas from the gas stream like a solid cone.

What would happen if you put them back to back then also. Small side to small side, then large side to large side? Kind of like this:

I think it has very good potential for us underpriviliged few who don't have lathes.

I'm wondering what would happen if you put the baffles in what would normally be considered backwards:

So the large diameter end of the spring is closest to the barrel, so that the spring can be pushed forward a little bit by the blast, helping to absorb some of its energy.

Perhaps I could even do a "Made in Montana" special without having to go through the ATF. (But first, I should probably check into how the guinea pig cases are faring so far...)

Probably not as good when you post to a public forum

I like the idea a lot . . . seems like a good way to do baffles on the cheap!

It actually speeds the gases through the can and make its not effective at all.

Check this out it will explain why you won't be slowing down the gases but speeding them up.

Its the De Laval Nozzle. http://en.wikipedia.org/wiki/De_Laval_nozzle

So is the general consensus that this structure should hold up under the stresses inside a suppressor? The yield strength for cold rolled SS wire should be the same as for SS tube of the same thickness, I think... if that assumption is correct then structural integrity would be the only question mark in the equation.

Are there any engineers who can weigh in on this? I think it might be a good idea but I'm in over my head when we start talking about structural strengths.

That does make sense...

I still think it's an interesting idea, but I suppose it would be more effective to stack them normally.

Not an engineer but I can tell you we have played alot with springs in the past and they DO NOT work well for suppressor internals.

I'm not looking for a spring, just a coil. I understand that complete rigidity would be impossible, but the purpose of this part would not be elasticity for reflexive purposes. It would simply be to mimic a rigid baffle while being easier to manufacture. Spacing between coils could be played with, but for proof of concept my first try would be with the coils wrapped right on top of each other at an angle that creates a 60 degree cone.

You need solid or for the most part solid chambers in a suppressor for it to be effective, too many gaps and places for the gas to get set free with that type design, there is a reason why the old cork screw baffle isn't produced anymore.

I will chime in here, if I may, and say that while it may not be the best option for baffles themselves, I do believe that it might be useful in the blast chamber. This is being tested in some hypothesis we are developing and testing as a result of the FRP thread.

I hope to present the results of these reaserches within one or two months. I have designed and caused to be built two new suppressors which, if everything goes according to plan, will represent a revolution. Or be expensive paperweights if I fail .

[travelingman]

"Made in Montana" will work for suppressors like the "Medical Marijuana" status works for providers of "legal" marijuana. When ATF decides its time you will be squashed.

[Blaubart]

True. Or, like medical marijuana, they'll just decide to yank it, and then you're on your own.

I was looking at differnt already manufactured items to see about the possibility of usingthem as baffels and came across these...


its a 45 rpm spindle adapter... I have never actually seen one but they are kind of expensive ... any one else have any other ideas of common items that could be used?

You may not get many answers to this as you have seen the recent ruling on Chore Boy Kitchen Scrubbers, not many people will want to add to the INTENT list.

this is true... even these would require machining... They are solid....

Thanks
