Hey guys. I'm not a gunsmith. But I am curious how gunsmiths in general feel about solvent traps?

I know it's a politically loaded subject. So I won't offer my opinion on it at all. I'm just curious how the smith's out there feel about solvemt traps.
 
Care to elaborate on this subject? I am guessing it is about keeping solvents out of sewers but that is strictly a guess.

Shows what I know. : - )

It's easy enough to get a real suppressor, legally that I think it's completely pointless. At best, you have a solvent trap that you never use, but it fuels your Walter Mitty fantasies. At worst you get caught shooting through one and now you're a felon. All for a suppressor that's much less effective than the what you could have had.

Edit: I'm assuming a US person.

I'm not a gunsmith either.

Solvent traps are just another example of how if a large enough percentage of Americans don't support a law, we will make a mockery of it.

Another example is in California where they banned bullets .50" or larger because some people wanted to fire the evil, no-sporting-purpose .50 BMG cartridge. So the firearms industry shorted the case (there was empty space since modern powders are more efficient than they were 100 years ago) and necked it down slightly to make the ballistically superior, completely legal .416 Barrett cartridge.

Gordon, my dear boy. I thought you said you wanted nothing more than leaving me alone?
And now you creep on my account and you look for posts I make?

Btw, you still haven't told me how you are going to save my life.
 
The guy intends making solvent traps - outside the USA but selling in the USA.

So what, solvent traps are legal. Leave the end cap off and it's a flash hider, also legal. Just make the part that screws onto the barrel and tell the customer that it's the same thread as a NAPA 4003, also legal.

If law enforcement needs something to do they can go after those *&(^## Russians who keep trying to put viruses on my computer.

That's the funny thing of it all. People started making and selling solvent traps made up of freeze plugs in a maglite flashlight tube. You put sillicone where the light switch once was. Very innefective and heavy too.

The BATFE though they were having a good laugh when they were issuing letters to those people telling them solvent traps are legal.

Than human ingenuity prevailed. Solvent trap conversions started getting better and better. So much so that the one I tried next to a Gentech can sounded even better than the much more expensive Gentech. Only a bit on the heavy side.

So the owner opened it up for me. And right away I was thinking - I can make this. I can make it better and lighter too. And that was the start of my new passion.

That was 3 years ago. Solvent traps have gotten much better since.

You are thinking of the old clunky freeze plug solvent traps. Fun project and affordable too, but terribly heavy. More of a ball and chain for your gun.

Btw, funny thing. I bought some freeze plugs on Amazon. I wanted to make sure my customers would be able to use freeze plugs if they want to go that route. Next time I went on Amazon, they have Maglite flashlight in my suggested items list.

And for the record, my tube size on the first line will be "D" size as in D batteries.

Gordon is worried about exploding solvent traps. He said if I don't do the treading right, it will explode on me. Gordon wants to save my life.

I like this whole thing about staying alive. So I am hoping Gordon tells me eventually.
 
Since the guts will never be perfectly concentric to the perhaps very expensive bore does such a device affect accuracy or is it short enough and the velocity is already maxed out and your are on the decel side so the effect is nil?
Not sure what the logic is behind making silencers or such illegal.
Likely a nice warm pissing down your leg type thing that gets you votes.

Great question!
And so far I find almost no reliable testing done when it comes to cans.

Most companies like SD Tactical just cut the tube to length and thread the two ends. Of course this produces inconsistent IDs. Batch to batch, and supplier to supplier will vary. I have some guys reporting that they could notice variations in ID within a single SDTA tube.

Than there are guys like Diversified Machine who bore out the ID to a consistent size and concentric to the OD....so they claim anyways.
This at the very least should produce better cans, but the DM tubes are twice the price of SDTA ones. The boring bar required to machine out the ID is gigantic and the process adds cost to the process.

I would like to be able to offer both bored out and cheap tubes. Let the customer decide. I think if you go with freeze plugs, the cheap tube will do just fine. But my bored out tubes will be machined to 1.370" ID. so the cups I will offer will fit in it snug within 0.003". If you go with the machined more expensive tube, that one will accept both freeze plugs and my custom 60 degree titanium cups.

And actually, the muzzle FPS tends to increase sometimes with a can. Not much but sometimes it does. That alone will create a POI shift. But so little only a long range shooter will notice it.

Hell, for long range guys, even a brake will create a POI shift. But that's likely due more to changes in harmonics with the added weight on the barrel than the brake disturbing bullet path and changing transitional ballistics.

There are just so many things that can affect accuracy with a can design. the thickness of the baffles and end cap creating a tunnel effect that disrupts the bullet stability, how straight the tube ID is, how accurately centered the holes are, types of clipping if the baffles are clipped, and so on......

Funny thing is, sometimes large holes in the baffles don't really affect the effectiveness of the can but the larger holes seem to help keeping the bullet more stable. I have seen a 300 BO can that outperformed my .223 can even thought it was bored out to larger caliber.

Once I get my line running, I'd like to film some tests and upload them to Youtube. Something nobody else has tried yet. And maybe, hopefully the videos will give me better exposure to potential clients.

Edit: I have a lot of wishes for the way this whole thing will go. But let's be honest here. Asians are not known for their quality products, just their quantity product. It's all a balancing act between cost and quality. My perfectionist nature wants to go all out on quality. But at this point I'm not even sure I can get a third world country to machine a titanium door knob.

Dammit! They got to you too?
I keep telling the wife those nasty Russians are the ones who put the porn on my drive.
I just hate those Russian!

That is interesting.
I am not a gun guy but I am a math and physics wave, force and movement guy.
Retained pressures wave in the can sort of like a longer barrel helping give more accel?
Is there a resonate frequeny wave here depending on charge mix and tuned length?
Way outside and slower speed but on the line of why a output pipe for a 125 is way different that that for a 350 2 stoke motor as you amp and damp differently?
Not my world of competition but I do know some very top world class shooters, they seem to not like these things no matter how well made and tell me this is TV and movie stuff.
 
Oh and btw, the ID doesn't need to be concentric to the OD. think about it. The OD could be shaped like a coke bottle for all I care. So long as the threads are concentric to the ID and the thread adapter lined up with the ID. Who cares what the OD is doing.

That would be the logical assertion. but we are talking a very small increase here. Not something you will notice on a 9mm at a 50 yard target.

You also have to think the explosion does two things. It pushes the bullet forward. but it also pushes the gun backwards. Hence recoil. In fact a shooter who holds a firm grip will see increased FPS over a guy who limp wrists the gun. I mean for a handgun anyways. So it's also possible that the added weight of the silencer helps transfer more force to the bullet which would be acting on a lighter canless gun.

That went way over my pay grade dude. You are talking Chinese to me right now. And to compound that, English is not my native tongue.
 
Is there a lower FPS with a limp wrist?
Trajectory gets screwed but not so sure on FPS on exit.
The whole force/mass/point of reference thing.

Just put it this way. The explosion pushes the bullet forward and it also pushes the gun backwards.
Now why doesn't the gun go flying backwards? Because it's heavier than the bullet thus resists acceleration more. So more of the energy is transferred to the bullet.
If you are shooting a 20 lbs cannon ball out of a 5 lbs gun, it's likely the gun will go flying backwards while the ball barely moves.

The more the gun resists backward motion, the more energy is transferred to the bullet which is a great deal lighter than the gun.
