Standard 22 Moderator 1/2 UNF x 20

[OldCrow]

I have another question.
Is it possible to run a tap in into the 1/2-20 threads. I have looked at the specs and I think that I could drill it to 12.5 mm then tap it 14mm-1.25. I haven’t read about anyone machining this stuff

I have ordered a 14 mm tap and a 16-1.25 tap and a metal insert 16 OD, 14 ID.
I will just loctite it in place.


Hunter

If you're going to do that get an M18 x1.5 tap drill it out and tap it.  Then buy an EZ Lok insert that is m14 x 1.25 inside and m18x1.5 outside. It will screw right into the tapped hole.  Use West system or similar epoxy.

On one of my 150 mm moderators your total run out cannot be more than 0.169 mm per inch or you will have problems with clipping.

You know what that probably won't work with one of my designs.  I did not think about it but the design of the attachment on my moderator probably won't allow that much meat to be cut away.  On a 25 mm the wall of the threads will probably be maybe 4 mm thick including the threads when it's printed.

If you cut a couple of millimeters out of that you're not going to have enough meat to hold up. I did not do that on purpose.  I did it to save weight.

I don't think one of my designs can be adapted that way.  Let me know if it works.

Here is the Avenger moderator insert I've just finished.  Unit is 40mm x 189mm with about 130mm extending beyond the muzzle and the rest inside the shroud.
Inquire via PM.

Mike, okay given all of this information I would like to get a Mamba in 25, and a standard in 177.
Not for Pinty. All 6 of my air rifles are American made. If I lived in Great Britain I would have Daystate, Brocock or Air Arms. If I lived in Sweden then I would have FX. This is for a Jefferson State Air Rifle. It’s the same thread as 14mm spark plug so inserts are easy to find.
The moderator will attach to the barrel tensioner that pulls on the barrel.

I will send a P.M.

I have a question.
Do any of you guys sell printed parts?
I might be interested in buying a couple of these.

Hunter

Here is the .177 Standard you asked for, next to a couple of other, longer suppressors. If you want it black I will paint it for you. I do need an address to send it to as well.

Hunter I have the Mamba in .25 printing for you now

[HunterWhite]

Jared, okay I will send my mailing address.
I have also ordered these with steel inserts from Old Crow.
I will have a bunch for testing. I think I may really like chrony work and night time barn ratting with these.

I've had to kill many a wood rat (pack rat) in the AC ducting that runs under my house with my suppressed Diana Bandit in the middle of the night while my wife was asleep. They get to the size of a small cat and I just lift out a floor register and drop something edible covered in peanut butter down in there and wait with the gun pointed straight down at the bait. It's pretty much the only thing I use that particular PCP pistol for and it is perfect for the job. I shoot the 2-4 of them that make up a family, then wait 4-5 months for another family of them to move in from the forest and repeat the process.

Here's that Mamba mod printing

[HunterWhite]

I am really intrigued by the whole Tesla valve concept. I read up on it a few months back and I kind of understood it somewhat. It seems that Subscriber and Old Crow Mike have done much more.
 ( Mike I have worked with some crazy smart individuals and they were almost all old spooks.) 
I wonder if anyone has used this Tesla valve concept with turbo chargers in aircraft and automobile engines.
Torqemaster , thank you for the cutaway drawings. 

¿Does this pull the BB out faster? JK

Inquire via PM.

Mike,
See attached Avenger moderator ( I think it is Subscribers design ) with stripper that reaches back over barrel.

I like the alignment help from it fitting back over barrel.

If you can combine the twe ?

The Avenger mods should also be a 1:1 fit for an Umarex Origin. Same gun, just not regulated. Many of the other parts can be swapped between the two as well.

Oh, Mike: those updated files you made with the fixes in them seem to working on my Klipper based Neptune printer where the old files had strange banding and lumps and gave "floating section" error messages in Orcaslicer . Cool!

[bduares]

OK The Wraith is printed and painted for David and the Standard and Mamba are printed and painted for Hunter. Once those are dried I will get them into the mail.

I still need addresses from you both so I can get them sent.

[bduares]

The mods are ready to be sent off tomorrow. Just waiting on Hunters address now.

I combined the cut-off inside shroud part from the Avenger model and the Standard model in my slicer program.

It turned out very good. Do not know if is any more quiet, but I think it is.

What slicer program are you using?

How did you combine 2 models into 1 model?

Nice work.  I expect it will be quieter than the original insert.  No idea how it will compare with subscriber's work but that "Standard" model is longer than the part you cut off.  I think it has one less baffle though.  No clipping?  I think it looks pretty good too.  That base piece is from one of Peter's designs right? 

[Robert 5mm]

I use FlashPrint 5 - came with my printer a Flashforge Adventurer 5M Pro

I loaded the Avenger model ( Peter's design ) - cut it 2 mm below the threads and deleted the bottom part ( the section outside of shroud )

I then loaded the Standard-22 model and moved the cut-off part up onto the threaded end of the Standard-22.

I then moved the cut-off part 1 mm down into the Standard-22 and saved to .stl file.

Sliced and printed. - It does have fuzzies - used long 1/4" drill and hand turned.

No clipping.

I just sent your Avenger insert to my printer.  Might get a chance to shoot it tomorrow depending on how my printing goes tonight. 

I shot the fuzzies out of the insert I made early this morning but had to run errands all day.  One print on the resin printer failed today (Hunters' Ember) but it looks to be back on track to finish tonight.  Then the Mamba.  That will  take all day tomorrow.  But it will look good when it is finished.
