Let me start by saying I'm no machinist, but I bought my LMS Mini Mill last year. Been learning from my mistakes ever since.
I've built a few 80%'ers and walking others through the same. Made a few jigs and other various tools. After seeing some recent posts by those that obviously have a better idea what they are doing, and probably MUCH better equipment. Then I figured what the hell.... First hole  Attached FileFirst side done  Attached FileSmall mills require crazy setups  Attached FileTrimming lots of fat  Attached FileFitting the magwell  Attached FileWaiting on delivery of the tap for the receiver extension. Then a little Cerakoat and she's ready to rock. ETA: Going back and reloading pics. GD PHuckitBuckit |

It was easier to see where it was catching when I could lightly hold the lower with both hands an slide it on and off the mag. Then once it fit just right, well I had to sit back and marvel long enough for a celebratory pic. |

I've done some cerakoting and some etching, not sure where this one is gonna go, but it needs to be something to do with ZERO.
Although, this is quickly becoming a "classic"  Attached File |

Good work!
Raw forgings are a pain in the ass because there's pretty much not a single square surface on them. Without fixtures and jigs, getting the first cuts right is tough. I'd personally rather start with a chunk of billet. BTW, I'm sure you're aware, but be certain to center the RE housing under your quill, and use the quill to guide the tap. If you don't, it's very easy to thread it crooked-especially as the tap is coming through the front and only making contact on one side. |

Got the tap and finished it this morning. No problem running a full mag. Gonna have to decide on a roll mark and some cerakoat.

I still haven't picked a roll mark. Too many other projects going. A couple for others and a few of my own. Ordered a few 80% AR-10 receivers. Still looking for decent 1911 frames. I have the rest of the parts, but haven't justified the coin for an 80% 10/22.
I did put a bit of time into tramming and adjusting the mill with some new supports, new vise and holder for my DRO's. I'll have to get some pics and post em up. Again, too much other stuff going on... |

Mostly the depth, or jaw height, I'd looked at getting some taller jaws but there were a few times I had to take the jasw off to fit something too big, the vise doesn't open very farther either, ~ 4". The new one is 5" and opens a lot more. Much more ridged. I had a 25% off and free shipping. I think it was $95 or so. About same vise other suggest from ebay, Shars I believe. |

More on the mill....
Front shot of the mill as is:  Attached FileDRO Mounts and line chains Switch box: Seems silly, but the boxes are cheap, I had the switches and outlets, each switch has it's own outlet. All of the connections are contained. And it works. The panel is 10ga steel, a couple magnets hold any diagrams I'm using. Right next to the DROs makes it convenient. Mostly, it works for me.

Cool, thanks for the pics! I like your air / vac setup.
I have seen lots of people (who have the tilting column) doing the column bracing mod. However, I have the solid column version. I wonder if the column reinforcement would be necessary. At the very least, it should make tramming easier. Is there a way to determine how column flexing is affecting the work? Did you notice an excessive amount? |

Oh it still flexes. With it running, cutting something you don't hold dear and not your favorite EM, stand to one side or the other and push on the top of the head. In front of it you can pull or push, it will most certainly flex and cut different. Granted this is exaggerated but the same concept as when you are driving the work into the EM. The end mill itself will flex some and the column will flex, deflecting from the true path you intended. While it may not be much, eliminating whatever you can is to your advantage.
All in all, I did it mostly to help with tramming, but the flex is noticeably less. I do all the "hogging" I can with rougher EMs which can cut pretty fast but it also puts a lot of stress on the column. I haven't done any major milling since the column mod, but tramming was much easier and I got it a lot better than it ever was prior. |

if you do any more 'in the white' receivers, you can anodize them at home. You'll need a car battery charger, lye, battery acid (you can usually get it from an auto parts store), distilled water, a couple lead or aluminum plates (they don't have to be very thick) and a decent plastic tub.
Remember, ALWAYS add acid to water, not the other way around. Also, you need to clean the part very well (that's what the lye is for). Lastly, you'll want some clothing dye. I wouldn't do this indoors since you don't want to breathe sulfuric acid fumes. Here's a simple tutorial for home anodizing. It does work very well too. http://www.thefintels.com/aer/homealuminumanodizing.htm |

Nice work, looks very nice.
A tip if you're interested... rough drill more holes with a smaller diameter drill. Get as close as you can into the corners, quicker and easier on your equipment than milling. |

With the electro etching, are you using the laser printer for templates, or are you having vinyl patterns cut?
Using salt water and a battery charger? The 4H and the arfcom look awesome! |

Consider putting an exaggerated funnel in your magazine well. I've done them by hand and extended the funnel into the front trigger guard area, as well as far forward on the front of the magwell.
You can also put multiple angles into the funnel, rather than a 45*. I would also strongly recommend anodizing before you Cerakote, just don't use a color. The anodizing will act as a case-hardening, and make the part more abrasion and impact resistant, as well as corrosion. I do a lot of Cerakote, and it will still wear, even on blasted parts that are totally degreased. It doesn't wear as fast as the paint-based products, but high wear points will see the base material come through. The most critical areas I'm concerned about are the pin holes for the fire control parts. Excellent work on this lower BTW. |
