Suppressor Alignment

Post by Historian »

Topic of misalignment of suppressor on some
commercially threaded barrels came up at
club meeting. Topic brought up use of
Geissele 5.56 mm hardened rod which is ground .002" under
nominal .22 bore diameter.

Measuring the actual rod gave an average of .21695 =>~.2170" diameter.

Inserted into a Ray Brandes threaded Smith and Wesson 41
barrel it slides in as smooth a glass ... perfect fit.

Interestingly the Geissele rod does not drop into the
original 5.5" 1965 Smith & Wesson 41 barrel. This extra
tight fit explains why this piece was as accurate against any match
pistols it shot against. In fact with a shoulder support
it was consistent at over 50 yards ... a 'snub-nose' .22
carbine.

The cost of such an accurate standard rod is far outweighed
by the security, peace of mind, and confidence it affords a suppressor
fit ... especially when it is home smithed.

Being a machinist,gunsmith and life long student of the gun has filled me with a wealth of information.The ubiquitous .22 bore size is all over the charts depending who when and what .22 cartridge it was made for.Knowing this pin gauges are often needed for best coaxial alignment,but a wiggler or hard center is better if true center is needed.Both are needed for best passage of bullets through a suppressor. Accurate threads and shoulders can be cut once barrel is dialed in.
The days of finely made weapons is long gone.Young men are seduced with CNC mass produced wonder weapons while we savor the artistry of the past.Who knows maybe things will change back as it is a Supreme day for our country.

The only reason after 243 years the government now wants to disarm you is they intend to do something you would shoot them for!

Again incisive observations from a wise and talented erudite man - CL!

It was disgusting listening to Princess Depends-The Leaker Feinstein
throw out that Our USA has 40% of the firearms in citizens' hands while being a small part of
the world's population Hey,Di, without Americas Toxic Males of WW2 defeating National
SOCIALISTs in Europe your dreams of being in the US Senate we could say would have gone up in smoke.

Stupid.

That's absolutely truth.

My upcoming integral 22 project using an old lakefield (pre-savage) barrel bore checks in right at .204"

No joke. Definitely a pretty tight bore all things considered.

While not exactly pertaining to threading, heres a topic I did involving some old school techniques in one of my builds that you two may enjoy. Definitely a lot of "old school" techniques went into it.

JohnA, Outstanding work Sir!

Have added your enlightening presentation
at Uzi to historical reference library. A joy
to see while we are in stasis awaiting HPA to
pass after Mid-terms. Hope does spring eternal.

Notice should be taken at your cleverly not polishing/smoothing
the back of baffle, introducing fluid logic surfaces to increase
inner turbulence. Inverse golf ball dimples.

Talent like yours always out paces 'dog trick' applications via
automation.

Thank you for cheering up a dull day.

Best.

Thanks for the compliment. Coming from you and your background, that's humbling. I just enjoy doing it Historian. I don't think that I've done anything that hasn't been done before probably. But I do enjoy trying to think of different things to do and seeing what kind of ideas that I can come up with. I too have noticed that a lot of new designs are all neat and tidy and computer controlled perfection. I don't think anyone would ever accuse anything I have done of that LOL

I actually try to NOT do that.

A lot of what I tried in that setup was based off some "old school" design in many ways, but by George, I have always taken a big interest in historical design. Especially during WW2 and wartime in general. A lot of research and innovation was poured into suppressors during that timeframe. And were being produced by companies who had no prior experience in making it. Lets' face it, a lot of companies that were making parts that that helped shaped history that only weeks prior were making clothes washer parts and farm tools and such.

If you are having a dull day, I'll type up a PM to you and send it later this evening. It's always fun sitting down and having a conversation with you.

Hey John A.
Saw the build, and like the old school looks.Did you use button heads on the end caps I like it.

:lol:

Yeah, I used button head screws on the endcap.

It's kinda grown on me to tell the truth.

And it's turned out to be plenty strong enough. Least on pistol calibers.

During WW2 the War Department Education Manual EM965 "Machine Tool Operation - Part 1 ( 1919, 1936, 1941
- Henry D Burghardt,* was published for training young men who did not have iPods, video games, etc, but made their own toys with orange crates/roller-skate-wheels, hammers and nails. On land or ships with turret lathes they repaired machinery and weapons.

The manual is so well written that is still instructive to reread. There is also a volume 2.
