Mac 11 (vmac 9 weld together)
Posted by Dangerous_Impact_104@reddit | GunnitRust | View on Reddit | 35 comments
Just finished parkerizing this bitch. Manganese phosphate solution from palmetto enterprise. This was a fun and easy build. I do wish the parkerizing was a little darker, but the two tone is growing on me. Going to buy a picatinny adapter for the rear and add a dual folding strike brace.

man I tried welding this and I warped like 3 sets of plates lol :(

Best to tac weld in a few places then weld like 1 inch sections on both sides evenly. Wait for it to cool, then weld the next inch, cool, and so on and so forth.

Personally I totally dig the 2-tone. Serendipity.

What was ur amps and wattage for the weld I don’t wanna over heat my plates and melt a hole in them
Dangerous_Impact_104@reddit (OP)
I used a cheap tig welder from Amazon. Set it at 48
According-Prize-3119@reddit
Would you mind linking the welder ? I wanna get the same one so the setting is applicable the same without worry of different settings affecting the weld

Do you have an argon tank?
According-Prize-3119@reddit
Atm no can get one tho just wanna get the supplies listed I’ve had this kit built for a min just needs to be welded
Dangerous_Impact_104@reddit (OP)
The model I have is the arc145ds by yeswelder. Mine came with the tig torch too. Should be about $130. I don’t think Amazon sells it anymore, but ebay should have some

Also this model is nice since you can use a standard wall outlet and don’t need a big ass 220v socket

Any jams so far n where u get the mag
Dangerous_Impact_104@reddit (OP)
I get some jams but I think it’s the surplus stem mags I bought, springs could be weak or maybe I just didn’t clean well enough

Hey, so follow up question. I see you have the same side plates that I have. When your selector is pointing towards safe, is it in fire and vice versa? After assembly and testing, that's how mine operates and I am baffled because I see everyone having the rear say safe and the front say fire but it doesn't seem to be able to go together any other way?
Dangerous_Impact_104@reddit (OP)
Nah man, you have something backwards. The spring that sits on the selector is tricky but I would advise you scour YouTube for assembly and disassembly videos for Mac 11s. They might vary slightly since there are cobray models and vmac9s, but they are super helpful when putting everything together. Just gotta pay attention to that safety spring.

I can't find online anywhere, which parts are supposed to be welded together? Is it just the side plates to the bottom? Does the grip get welded on? Does the rear aiming sight? Can you point me in the right direction?
Dangerous_Impact_104@reddit (OP)
Side plates get welded to the bottom. The grip gets welded along with the trigger guard to the bottom. Then weld up the back. Check Amazon for some arc welders that include the lift torch.
AlaskaMatt@reddit
And the little bracket in the front too then, right? With the flat part with the hole in it down?
Dangerous_Impact_104@reddit (OP)
Yeah

I just did 2 and they came out sick. I cooked my receivers for 45min and they came out plenty dark.
Dangerous_Impact_104@reddit (OP)
Nice! Where did you get the park solution from?
LAWcapAdapter@reddit
I used duracoats parkerizing solution. Have used it on several guns and they all come out with a nice dark black finish.
