Good job sir.
I have anodized mine, just to get all the surfaces covered. Cerocoat seems to keep coming up as a tough durable finish too. Go Cerocoat |

Very nice. You make that look fun/easy. View Quote Oh no it wasn't easy per say. forget the videos everyone makes like, they don't tell you everything believe me. It was tough -- not really just because it was my first time and errors can happen, Yes and it did, but no biggy, I can weld it, and the and clean it off with dremel or endmill. I bottom out with the 1/8 after the second day and after four cuts with the 1/8. I was so mad. Just started and my luck. I can fix the hole on the bottom. Or I may just let it go-- It has nothing to do with the function or integrity. |

Just consider that one extra hole as a drain hole, otherwise it looks pretty decent, then you got to do a paper weight, or Zero lower. Now that's a project on a manual mill. Fun, and lot's of chips. Much more than the 80's.

is that the harbor freight drill press and mill vice?
I was looking at the reviews of the vice and they sounded awful. It seemed to work ok for you though? Is it true that you need their drill press in order for the mill vice to connect to the table properly? The project looks great! |

You need to secure it down once drilling with the 3/8 or will start walking on you. It almost happened to me on the right side. For endmill I had better luck with 1/4 milling with speed running abut 955.The hardest part would be the first milling pass. Try to get .5 or less flute and increase by 1/16 at time. Much better results and goes through like butter. for finishing the bottom I went with .31~ 5/16, much less chatter. Get ready for lots of shaving/and clean up and don't run the press hard, every 1/8 pass I let it cool down for 15 min. Overall the press is not the best but does the work EACH SACLE ON THE PRESS TABLE IS .0625 SO four for a .25 depth and so on. I decided to go with duracoat black. Oh-- the oil drain is now plugged LOL I weld it and after the finish is applied may hard to see or at all. |

Duracoat is easy as hell, just stick to the ultra flat colors, or get extra flattener. If I was doing just one lower receiver though, I'd probably get Cerakote H and bake it in the oven.

That's amazing! Mostly because you did it on a Central Machinery AKA Red Dragon drill press! Good work. My advice is- leave it unfinished. The aluminum will look great with black furniture.

I'm doing a build right now, it started with a SS barrel and then an un-finished receiver, now I saw some un-anodized uppers and SS flash suppressors and I'm thinking about going total SS/raw aluminum.

I just got a jig that looks like yours. Question: do you drill the FCG holes first or last? I would naturally assume last, but the instructions I got say to drill the selector/hammer/trigger holes first.
So you ran a end mill after you drilled it, right? What cutting fluid do you use on aluminum? A helpful hint: I'm going out today to buy these little collar things that go over the drill bit and attach with a set screw, not sure what they are called, but I am useing them to prevent drilling/milling to deep. |

I like that red/white dot safety markings, I may emulate it on my next zero or 80....looks good.
|
|
|
I can answer that, most likely it's just to help lighten up the lower a tiny bit, since steel is allot heavier than aluminum as you know. And the steel is stronger, so it don't take as much of a structure to obtain the same strength. But I could be wrong.

My 80% lower is not polished on the 308. It came like that from the manufacturer. It is shinier than yours which appears to be sand blasted or bead blasted. I still think yours would look good in the raw. R |

Thanks. I've done 7 lowers (5 in duracoat, 2 in Alumahyde II) and have always sprayed them completely unassembled. Wait 14 days before assembly and there hasn't been any issues with marring the finish. Painting a partially assembled lower seemed to work for you so I'm not knocking your process, I'm just stating my preference. I personally don't like to coat parts that are supposed to move independently all at the same time while assembled. |

View Quote I know what you mean, I was apprehensive about the front/rear pins and FC pin, I may need to scrap off excess paint in order to make it work. Only thing I left was the BS. Now, that Iam looking at it, I should have coat it the buffer tube.nut and sling point too. I assembled the complete lower in oh about 36 hours. Now waiting on the upper should be fun as well. I will not apply any oil/or shoot for a good two weeks |

The only other way I can think of to "fix" the problem is to re-drill the detent hole or file/grind or mill your rear take lug on your upper so It can clear your rear take down pin...either of which is not without it's problems... Good luck. |

Good luck. Not seeing he has to grind down anything. He's already removed the offending detent. Slam that upper shut & shove the takedown pin in. The detent is only to keep you from losing the pin. If OP is concerned about losing the pin, buy another one - they're cheap. I've never gotten around to installing my rear detent - I change stocks out about every other week @ this point, so I'm more likely to lose the detent than the takedown pin. |
|
You can just toss the detent and get a 1/4" pin with detent ball from a hardware store. Once I had a problem like you do, I took a 1/4" drill bit, cut the shank off to the length I needed, turned 2 grooves in it on a lathe and put an E-clip on each end. Yeah, not as easy to take down, but shit, how often do I clean my guns anyways?
