Looking for screen washers

[YugoRPK]

I have a Hi Standard I want to do old school with screen washers. I have enough cans that work well. Anyone know where I can get screen washers? Bronze or SS. Punching out a hundred myself doesnt sound fun and getting the holes concentric sounds less fun.

This makes it sound like you are wishing something second rate !

Size #10 bronze screen would be a estimate of original material. I'm afraid you will need to punch out each one for round shape then the hole. Using copper chore scrubbers made into rope and compressed around barrel will net higher SPL numbers than the original HDMS bronze roll.

Your knowledge good Captain never fails to impress.

Yes I'm well aware that bronze screen exists. I need washers or better yet washers with a 1/4" hole in the middle. Its the concentric home thing thats the problem, Short of designing and building a punch set, which isnt impossible to be sure I dont know there is anything off the shelf I can do,

Screen washers WILL be second rate. I recognize that. Looking for something original sounding.

The HDMS has quality's that few know about. Overall performance is about 24db reduction without FRP and high accuracy.
You can buy brass screen disc's but the mesh is very tight and a bore hole will still need to be formed.

An solution seen so long ago for an alternative to replacing
bronze screen washers that were tedious to push out:

0. Making a cylindrical scaffolding the diameter of the
bullet hole passage and tightly wrapping bronze screening
around it to the desired diameter.

1. Roll small hole stiff 'chicken wire' around a say .30" mandral
or rod the length of the can section make a stiff cylinder
scaffolding.

2. Wrap bronze screen, e.g., "Bronze Wire Screen 36" Wide, 18 X 14 Mesh - No. 3001826"
around the stiff wire scaffolding. Tie in place with booze wire. Slips into can
with same shape as stacked washers ... and easier to replace.

3. A variation would be to wrap Choir Girl 'braided-donuts' around chicken wire
cylinder ... replaceable ... and slipping into a thin aluminum sleeve.

4. Similar to replacing water filter in dark room Arkay filter.

Oh, Gosh!! Gasp!

Hope Arkay steel dark room water filters will NOT be added to list
of 'Silencer-Parts' and be put in along with the Fram Oil Filters.

Jocularity at its best.

After seeing a museum quality HDMS and its packing I have allot of respect for the bronze washers and their roll in suppression. With the extensive porting used in the HDMS I can't see much suppression from the roll of screen wrapped around the barrel. The tech developed by Dater for the early AWC pistol is the way to go. The compressed strands of metal rope dose stellar duty vs a simple tube of hardware cloth. If you limit only as much porting as necessary for velocity control matched with either bronze washers or oiled felt You might get upwards of 26+db-or still fairly loud by today's standards.
Why don't you try for a short integral using the best tech and settle for the loud report and the ease of maintenance the modern design will have. Aim for a 6.00" tube most measure 8.00".

[Historian]

The Good Captain recounts the lesser known innovative genius of Dr. Phillip Dater.

For those who have actually seen the OSS HDMS pistol in a case or most unlikely
been associated with their use in a long past 'unpleasantness' it was a marvel for its time and
in some sense a timeless beauty. But disassembling it was polar opposite to taking down
a Smith and Wesson 41.

The Captain's suggested variation on the original HDMS innards brings up another possible variation
to be considered, under the heading "Sleeper" as used by some of the gray beards
on this site during their 'mis-spent youth' in the '5-s and '60s.

"A sleeper* is a term used to describe a car that's significantly faster in performance than its outside appearance would suggest.
These types of builds are popular all over the world, as drivers get the fun of surprising competitors in races
when their car is much faster than it looks."

Getting back to your project a novel, efficient, and minimalist approach would be to
use the outer tube exactly like the original HDMS but internally implement Don Walsh's
brilliant and purportedly successful operation in the field:

An added benefit is that you would be guaranteed to not have baffle strikes.

A .22 variation was to wide-slot the tube ⅓ of the length
right after the barrel, allowing most of the gasses to enter
the full length of the can with Dater's coiled Char-Girl, or is
it now called Char-Boy donuts.

Please show us you final implementation.

If you are dedicated to the originalist design, I suspect you could probably find someone with a water jet cutter that could knock out serious production-level bronze or copper screen washers, or you could just "Design" the washer and send it off to Bokers for production. I suspect that there would be a few people out there willing to pre-purchase some of your washers for their own purposes to help you offset the costs. Functionally, I suspect, but have no actual evidence, that the rolled screen would be just about as effective. If I did it, I would probably roll copper screen ( Which is pure copper and available cheaply for rat-proofing ) over a mandrel, and tack down the first and last rolls with silver-solder to keep it dimensionally toleranced. The washers in the OSS version would get blown apart at the ports, making a godawful mess of the copper screen. Of course, how many German agents does one really have an opportunity to assassinate?

[Historian]

"... Of course, how many German agents does one really have an opportunity to assassinate?"

Alordnapa, you indeed asked a deep question of how many
German National Socialist (NAZI) agents are left anyway to warrant using an original OSS .22 HDMS.

Coincidentally this week for the fun of it screened from my DVD collection
3 of the best stories in line with the above:

"The Odessa File*"
"Boys From Brazil.
"The Fourth Protocol "** "

And did not the MOSSAD track down Eichman and brought him to trial in Israel?

Who can tell. Why take a chance!

Well, thankfully the world is always happy to generate a whole new crop of Nazis, Communists, and Amway sales people just begging to receive 40 grains of quiet lead when they least expect it. Going out and double-tapping 115 year old SS Privates at this point hardly seems sporting, but to each his own.

[Capt. Link.]

Other than the need to take out the current ne'er-do-wells screen washers can't be destroyed by port blast as they are in front of the muzzle and not around the barrel.

[alordnapa]

Not in every type of can using washers. In every application, they are still essentially consumables, so if someone was going to take the trouble to run up a bunch, it would be prudent to make spares!
