Solvent trap kits

They're not. I use a 5C rotary indexer with a 3 jaw chuck that I mounted a 25 RPM DC gearmotor to, which is powered by a PWM speed control, and I use a momentary switch in my support hand to control it. So the work is rotated by electric motor, but I still hold the torch.
You should tell him to grab a foot pedal to replace that switch and free up his support hand.

I think that was discussed sometime previously. I don’t remember his justification for doing it that way, but there was a reason. :confused:

Probably because he used a foot pedal for the welding hand. Most of us do.
 
The form 1 is confusing. I should just be ae to walk into walmart and pick out one that matches my shoes.
You have questions on how to do the forms themselves? Paper or EForms? Ask away...
 
For those that bought one of the eBay kits, or are considering it...Nick @ ECCO just posted this:

I recently got 4 of those to evaluate for the F1 crowd, since as an SOT I'm out nothing but $35 on the 4 kits and a little bit of time if they don't work out.

https://www.ebay.com/itm/11Pcs-1-2-28-Auto-Fuel-Filter-1X6-Solvent-Trap-Napa-4003-Wix-24003-Black-Z2N/264418391086?epid=23033677149&hash=item3d9090742e:g:NjUAAOSwzBJdRO8h

I'm still working on the review, need to do some metering and then tweak on them and do it again. It's possible to get decent suppression with them, but it's gonna take a little more than just drilling & clipping to do so. They only come with 7 cones and have too much blast chamber. Also, the anodizing is uniform but extremely thin. They are billed as being all 6061, and though I don't have an analyzer, they do behave like that material. I'll do a full write up when I'm done, but the cliff notes are:

-If you're only going to use them on a rifle, they're not awful with just drilling and clipping (I used a double radiused clip with a .280" aperture. Clips aligned). On a handgun, they're pretty loud and have horrible FRP.

-If you want to use it on a handgun, I'd suggest buying two kits and using 5 of the cones from the second kit. Obviously you'll need to shorten spacer and each cone to fit them all in.

-The cones will perform much better if you use a 60° countersink or center drill on the inside to create a very sharp transition from the rear face to the inside of the cone.

Hopefully I can find time in soon to do the metering and additional changes, give you guys better info.


I’ll copy/paste any updates he provides when I see them.

Somebody made this comment:

I’d worry the alloy is substandard and subject to failure. Aluminum cycle fatigues so good material strength with a margin of safety is necessary in the long run.

...and Nick gave this reply:

Eh, .22 LR chamber pressures are only 10,000-15,000 PSI to begin with, and the attenuation in even a 3" barrel results in an exit pressure of around 1,500 PSI, which is pretty much halved again when it opens up into the suppressor even with basically no blast chamber. These tubes are 1.050" OD/.875" ID, so .088 wall. 1" 6061 tube with a wall thickness of .085" has a working pressure of 1,700 PSI and a burst pressure around 7,000 PSI.
 
Looks like most of the cheap ones are gone. I have one more on the way that has SS cups for $9.99.
 
FYI - it’s looks like eBay removed all these solvent tap kits.
I posted that in the AR15 thread and Nick gave a short reply, then continued with his testing info:

There are still some. Search "fuel filter kit" instead of "solvent trap":

I'm sure they'll keep popping up.

I did just finish up my little experiment with them, and the results are actually pretty surprising. I'll do a dedicated thread, but in summary:

-They don't work well without clipping. Even on a rifle, you'll see high 120s/low 130s

-They do quite well on a rifle with a double radiused clip, even better if you use a countersink on the inside to get rid of the tunnel. They were hovering around 117 dB on a 16" Savage Mk II with CCI SV, just barely above the dBs put down by TBAC TD22 and my Ocelot (114-116).

-They'll be hearing safe on a pistol if clipped, but closer to 9mm volume, and with a significant FRP.

-If you use 2 kits and make a 12 baffle can with a short blast chamber, they even perform OK on a pistol, though not as well as a quality commercial can. Low-mid 120s. TD22 and Ocelot are about 118-119 on pistols with CCI SV

-On my CMR30 SBR, the 12 baffle version was pretty loud, probably hovering right around 140. I didn't even try the ones with 7 cones.

-With ablative, they're really not terrible on a 9mm, but pretty loud dry. I didn't actually meter it on the 9, but I would say mid 130s wet. Over 140 dry.

Are they worth a tax stamp? If you don't mind an all aluminum can, probably. I'll see about having the parts X-rayed the next time I'm at my aluminum supplier's outfit, but I have no reason to believe they're not 6061, so the material isn't horrible. As I mentioned, the anodizing is really thin, but a lot of kits are raw anyway. The thread fits are a loose class 2, but they work. Other tolerances aren't great, either, but with .280" apertures I had no baffle strikes after a couple hundred rounds on multiple hosts, so they're tight enough.

So, I checked with the machinist I’ve used, who is real popular in the F1 silencer world. Same one that made the Ti tubes and all the end caps on the first six. (The SS tubes from Apogee). He happened to have some 1.25” Ti tube ready to go. I canceled my first kit and said I wanted two 1.25” instead. One would be for 22, and one for 9. I specified 6.5” long, 7 baffles in each, evenly spaced. One would need a 1/2-28 DT adapter and the other a 1/2-36 DT adapter. I told him it didn’t really matter to me as far as material, but he went with full Ti...fine by me.

The aluminum tubed kits came in two months ago. The two for me showed up today. Open the box, started to unwrap one, and paused for a pic.

The tubes are the same, the end caps are the same, and the spacers are the same. The direct thread adapters are only different in the thread pitch. The radials are sized differently for 22 vs 9. I laid everything out and had this:

You can see the face of the cone is smaller on the kit on the left. Each radial has a rim on top and bottom of the skirt, so the spacers slide over it and seal the stack off from the tube.

When you stack it all up, you get this:

Here’s a shot of the 15-22 with the Spectre:

View attachment 133695

And here’s what the larger OD can will look like:

View attachment 133696 View attachment 133697

The ID on the 9mm upper I want (4” barrel, 6” rail) is almost identical to the 15-22...so the fit should be similar, although it’ll stick out of that rail more than it does on the 15-22.

What’s left:
1. File EForms next week. Already have them filled out online, just need to pay and submit. Wanted to make sure the tube fit the 15-22 before I submitted.
2. Visit @TARHEELSTATE to get them engraved.
3. Visit @Magdump to get them cerakoted (high temp flat black)
4. Visit machinist to get bore opened
5. Assemble and shoot!!

If you actually have the ability to run a lathe yourself, you could easily build your own for <$100. The stamp is the same $200. But an EForm 1 is likely to be approved in <30 days, compared to 8-12 months for a paper Form 4.

Anyway...figured that would be enough to get a conversation started.
Here are a couple pics of the DM kits after ECCO handled the boring & clipping. He also added the cutouts to the inside of the DT adapters so I can use a 12pt 5/8 socket to remove them if they get stuck on the barrel (both will be dedicated to builds where they’re recessed).

Here are several closeups of the DM kits after Nick worked on them. THSF did the engraving today, and they’re getting cerakoted (along with the tubeless cans) this weekend.

Now, after they’re cerakoted, they’re going back to ECCO for something I didn’t think about while he had them. DM puts a spacer after the last cone, which seems to be a waste. Nick is going to remove that spacer, push the stack down, and make a new blast baffle for both the 9mm and 22 kits.

Gotta give credit where credit is due... you have been sending it lately with your F1 cans!

Will be interested to see how they perform next to your commercial cans. I'm betting the 22LR will be right there in terms of suppression.

When I get it back from Nick (which will be after it comes back from Cerakoting), we need to hit the range so you can hear it for yourself.

I have no idea what to expect.
 
I wonder if that would work with the SDTA D tube. Can’t figure out what size it is. Text says 1.6 but diagram shows 1.5
Not sure.

Unrelated, but I did see this when somebody mentioned the .625 ID on the hex:

Just perfect for a 5/8" drill bushing to fit and get you a perfectly centered hole!!
 
Somebody started a “baffled by baffles” thread on ARF, and it’s probably similar to the paralysis by analysis some of you are going through. Nick gave a pretty detailed answer I wanted to share:

It's really hard to go wrong with 60° cones, but clip style, count and spacing need to be appropriate for the type of cartridge you're suppressing.

In my experience, 5.56 cans should have as many baffles as they are long in inches, with progressive spacing and single radiused clips.

.30 supersonic cans aldo do well with progressive spacing and single radius clips, but need more length and more baffles. 8"-9" with 9-11 baffles in a 1.5" OD tube does nicely.

For subsonic stuff, more cones, even spacing, and a double radiused clip of smaller dimensions works well.

For single radiused clips, I like ~1/2 of aperture diameter, slightly deeper than they are wide. For double clips, 35-40% of aperture diameter with the same 105%-120% depth.
 
Found a lot of options here...monocores, K baffles, cones, etc.

I had one with SS baffles arrive today. I got an email from the ebayer that I bought one from saying that they still have them and had pictures of 8 different types including the monocore ones.

We have some new model fuel filter want to show you.

US ship and wholesale price as we are manufacturer.

Which model are you interested?

Thanks,
 
ok so I ordered a couple solvent traps because I prefer to go the cheap skate route. The first one I got was for a future .22 and that one is small as you would expect but fits the barrel of my .223. So I wanted a larger one and as far as I could tell the 5/8 was larger than the 1/2 (Math) so I got the larger trap. Got it yesterday. It fits my .223 but not my new PSA 300blk pistol. The 300blk barrel threat is WAY bigger. What size is it? going to start the e-form here soon and will need more guidance because I'm an idiot.

300 is usually 5/8” x 24

(Almost) Every 22 I’ve seen is 1/2-28, and (almost) every .223 I’ve seen is also 1/2-28...so it’s no surprise the first one fits both.

If the new one fits the .223 but not the 300BLK, it’s also 1/2-28. As mentioned above, almost all .30 barrels are 5/8-24.

If you bought one advertised as 5/8-24, and it fits your .223, you need to contact the seller for an exchange.

I guess they could have just sent me the wrong end cap. Not worth the effort to return. I'll find a cap.
 
Sneak peek of the cerakote job:

I’ll pick them up tomorrow.
 
Got a link for this by chance? Interested in a 5/8-24 monocore kit...
I was just doing a google search. Maybe try wish.com and search for “solvent”?
 
@BigWaylon was by earlier and was showing one of these

Compared to the commercial made .22 can all I could hear was the firing pin drop then the bullet cutting tree limbs It literally sounded like an air rifle

Imho the commercial can was a wee bit louder.
