Cold weld unitizing the M1A gas system - Part 1

TacticalTeacher said:
Keep us posted on how it stays together. I did the same experiment but with Bisonite back in 1987 on a TRW gas cylinder. All stayed together until I knocked the glued gas cylinder off the barrel for an annual cleaning. :cool:

It fell apart when the wooden block and mallet were applied. No sweat, It was now a good reason to take it to my welder buddies and weld things up properly. It cost me a couple of coffees... :)

Glad you tried it!!!
Like Mrs Frizzle of the magic school bus show says, "discover & make mistakes."

And this is from your teacher, "It's a Norinco; you can only make it better."

Cheers and look after Da noobs around here

I'm guessing Miss Frizzle never had any child support payments.

Yup, I trust all my TIG needs to Tony. He's got all my gas assembly unitizing jigs down on the coast.
He was actually lightin a fire under my azz to get my m14 clinics back up and running out of the shop out back at his place. We'll see, I'm keeping my work load light and my comittments lighter hehehe....my two favorite words right now are.... Fish on ;)

I would really like to participate in one of these clinics. Can you keep us informed?

I might fly out for it just to meet to meet the M14 legend.

the clinic discussions in this thread were from last summer I think.
I am running what is to be my last m14 clinic weekend, on dec 6/7 .
Unfortunately we are booked full as of yesterday.

I've been asked by a good friend to run two high end steel fabrication jobs for meadow fresh dairy and united flower growers. It's some pretty serious fab work and it is the work I truly love. I'm "supposed" to be on long term permanent disability and I've said no several times but the offer is to good to pass up. this will see me pretty much too busy with my head in the game to be doing much online or with the rifles for a long time.
If yer gun club (in lowermainland) wants to organize an event and wants me to run an m14 clinic, I "might" be into that as I will be in the lowermainland for the fab work.
anyhow, I'm derailing this thread , my apologies


neat stuff with the JB weld. I wonder how it will withstand rapid fire?

Here's an update for any of you who might consider cold weld unitizing as an option.

Since the first post I have fired over 500 rounds ranging from pricey hunting rounds to Chinese milsurp and everything in between. The JB weld has held fast with no signs or weakening. Overall I could say my groups are tighter by about 1 MOA. I average 2 MOA with irons at 100 yards.
I think the trick to a lasting bond is in surface prep. I spent a lot of time sanding and degreasing contact areas.

Anyway, it worked for me so there's no reason it shouldn't work for you and if you can't afford to do it right, at least you can do it right now.

Interesting, I'll have to try this. Thanks for sharing.
 
When I unitized my gas cylinder I followed the USAMTU procedures is was to say the least a long process and no welding required and at the time gas cylinders were plentiful and easy to get
 
I tried this cold weld method and proceeded to my home built crown land "CQB" course. The "welds" failed after about 5 runs through the course. Each run is 15 targets with 2 shots on each. The rifle was allowed to heat up considerably for the test.
After thoughts... While this method may be okay for a bench rifle or a hunting rifle, I wouldn't waste time doing it on a run n gun rifle where she will be runnin hot most of the time.
There is an outfit in surrey BC that specializes in Tig weld unitizing. I can pass on their info if needed.
