Homemade AR lower forged from aluminum cans

[meatman]

This is my buddy's brother-in-law who is an ER doctor in Virginia. It's pretty impressive that he has time to tinker around like this in his spare time.

That's pretty damn cool. Chances I ever get close to doing something like that are zero.

[colorider]

That guy has some serious equipment. And skills. And TIME.

Sweet, most expensive cast lower ever

[Circuits]

Casting, not a forging, and using the wrong alloy for the job (beverage cans are 3004 or 3104), so it's good he made it beefier than a standard lower profile. Looks like he didn't end up with any obvious voids, so it should do just fine.

Very neat to watch, though!

"I'll see your 80% lower and raise you ..."

Neat to see. My issue is the extra steps in casting in the voids for the mag well and trigger cut, along the specific shape seem like a partial waste of time. If one has access to machinery, it seems to me to be a better use of time to simply cast a large block of AL and take the extra machine time to mill out the outer shape and inner cuts. I mean, its cool for someone to show off their sand molding abilities, but if you have access to the machinery that he has, why not just cast a block and machine the whole enchilada.

That's pretty bad ass. He has some serious skills.

I'm sure this video has made Liberal's heads explode. Therefore I give this video a huge [Awesom]

I'm guessing that besides showing off casting skills, it looked like he was close to his crucible capacity... multiple pours aren't feasible unless you have more than one furnace and crucible to pour in a row.

and a big block of aluminum would need more than the capacity he has.

If anyone wants undertake this minus the casting part k and k surplus had some big chunks of billet aluminum last time I was down there for 2 bucks a lb

[OtterbatHellcat]

That's pretty cool.

I think it's Alreco aluminum up towards Henderson on Brighton Blvd. also has billet chunks for stuff like that too.

[thvigil11]

There used to be a magnesium extrusion place in Denver that I serviced equipment at. Kinda wish I would of raided their scrap bins back in the day. The end cuts they had would have been perfect size for a lower blank.

[gnihcraes]

Alreco, good stuff. Love going there and picking up pieces.

[dorsum]

That was cool to watch. Wish I had the equipment for that.

[Bailey Guns]

That is seriously cool. Hats off to that guy.

[Duman]

Wow!

I liked the high speed machining and mold prepping....

[Gman]

The genie has been out of the bottle for centuries. This just goes to show how pointless trying to put it back in the bottle really is.

I've got a mill capable of this, but doesn't have DRO like that yet... need a lathe, band saw and shop space right now.

Currently doing demolition on 3rd house on my property here... anyone want to do a remodel job on a house in Canton? I was drafting an ad for the wanted section, but not finished...

[DavieD55]

Thank god for that.

[Skip]

Watched the whole thing. How cool. I like his safety gear while working with the Al. :)

BPTactical needs to see this! Assuming he hasn't...

[Hound]

Really taking it to another level there.

For that matter, why even mess with casting, when a raw forging is on sale?

Never done business with them, was just a quick web search

[ray1970]

This reminds me of the video where the guy turns a shovel into an AK receiver.

Oops. Not up on my metallurgic processes. Cast, sorry, not forged.

[BladesNBarrels]

Makes a person appreciate the work involved.
Way beyond my shop's capability

I think the point of the video is just to show that it can be done. If we're talking about the easiest way to get it done, why not just go buy a lower?

My thoughts exactly. The dude is a doctor & this obviously a hobby of his. He did it because he can basically. It would be cool to say I made an AR15 from beer cans that I even drank just like it would've cool to say I made this AK47 out of an old shovel.

Looks like he had fun doing this. I would have.

So cool
