Covering... Legalities Milling & machinery Quality of 80% available lowers Quality of Jigs Home Anodizing Repairing screwed up lowers How to mark lowers Etc Etc Etc It would be good if for no other reason than to pin some good threads about each of those topics to the top! Those things all come up over and over again and I find myself sending noobs links for recent threads that covered the exact question they are asking. I think blueprints/plans/dimensions probably fits under milling, but if not, maybe another topic. I am also assuming that other tools discussions like punch pins, drill bits and taps, etc. would go under milling & machinery... maybe "milling, machinery, tools & blueprints" |

I think that's a hell of an idea. I hate trying to go all over the forum looking for milling posts and what not. One area to put them all would be the way to go.

Hell, I'm planning on purchasing a Sieg X2 Mini Mill. Either a Little Machine Shop 3990 or a Harbor Freight 44991. This will be for ONLY milling out 80% lowers.
I need help on what vise, tooling, etc and where to purchase it. |

They have great customer service and reasonable shipping, they also get it out the door very fast. |

I think the ONLY people that are going to vote NO are members who aren't interested in finishing an 80% lower.
I haven't seen this much interest since around 2001 when The Tannery Shop was selling their 80% cast lowers. |

Yeah, I cut out one of ARs4ever 50% lowers on a Bridgeport with the help of a friend looking over my shoulder EVERY step of the way. Back then The Tannery Shop cast A356 lowers and ARs4ever 50% lowers were about your only choices. IIRC, The Tannery Shop also offered lowers cast out of titanium and beryllium copper. |

I just got the Grizzly version a couple of weeks ago and got lucky it came with the vises, tooling and extras that you normally have to buy, but I have been looking through the auction site and if you don't mind good used equipment that have been some really good buys on a lot of the stuff you need to get started. I would not have bought this set up, without the tooling due to the fact it has the MT3 taper and most mills these days have the R8 taper, but I got the mill, a 10 inch lathe, all of the tooling for both, vise, drill chucks for both machines, collets, 20 piece end mill kit and the extra upgraded table for the mill for less than $900 so couldn't very well pass it up. |

In my opinion the LMS 3990 is worlds better then the Harbor Freight offering. There are better mills out there then both of them but for the money the LMS was my choice.

I have the LMS 3900, I would suggest against the tilting column version, but otherwise I am VERY happy with it. I have done a lot of mods, each one helps, together they make a world of difference.
It is more than you would need for a dedicated 80 completion rig, but any smaller would really limit how much else you can do with it. |

The column on my Grizzly I just purchased has been trued and fixed so it is basically a fixed column now, the guy I bought my equipment from was a retired machinist that got into gun making and he set it up pretty nice. Anybody getting an X2 mill, spend the money and upgrade to the belt drive system over what comes with it, it is well worth the money! Forgot to add, I had to travel over 400 miles to get mine so, with the cost of gas, I am still in my set up for less than a grand.

Mine is non tilting. I bought it used with a complete $350 LMS tool kit for $650 delivered to my door. Since I saved a few dollars on the initial purchase I can stand to afford a few upgrades.

I would love to see some discussion about the various mills by those who have done the mods and been using them for a while. I am trying to justify putting a 3 axis DRO on mine, but I don't know that it is worth the cost for just doing 80% lowers.

The DRO'S add the most functionality. But the air spring, column braces, spindle lock, LED's, tach, I'm sure there are more. They all make a notable difference. If you are unsure, or just trying to go as cheap as possible, get the igaging DRO's from eBay or amazon. They are accurate enough for all but the most precise work. I got all 3 Axis covered for about $100. I could go on and on, but here's a link for those that want to read more: My 80% Thread with links to my Zero Percent Project and Mill buying thread. |

I am just guessing here but it's possible a good portion of the 80% community would only like to read what a dozen or so of us are willing to disclose. I understand that an online forum is a broadcast and some may even say we could be irresponsible for offering up first hand knowledge regarding manufacturing. Any thoughts on that? Any laws reagarding it?

This was exactly why the gunsmithing forum was set up, to keep the Assemble it Yourself guys separate from the metal cutting home workshop guys.
What we need is a subforum called "Send it to ADCO" to keep both of these forums geared to the home shop guys as it was intended from the outset. I choke on my bile seeing "Send it to Adco" for simple work in a home gunsmith forum. Honestly, guys, stop posting that. |

That's the last thing I'm sending to ADCO. I think MOST members who are interested could accomplish milling out an 80% lower, as I posted above I machined out a lower years ago that the ONLY thing completed was the mag well, not the mag catch, not the takedown pins, I had to deck the receiver, cut the hole for the receiver extension, etc. AND it worked when I was finished.

IANAL, but I can't see how there could be anything illegal about merely TALKING about manufacturing or sharing knowledge. The 1st Amendment clearly protects that kind of speech. What BATFE has said consistently is that you can't offer hands-on help while someone is completing a lower. They've lately mucked up the water by being very confusing about whether you have to own all the equipment yourself or whether if you loan someone an allen wrench you are "manufacturing" for them. And even at that the letter everyone is worried about they are mostly only talking about shops who are in the business commercially of doing machining setting up CNC machines with code where all someone has to do is put their lower into the machine and push a button. Telling someone on a forum how to drill holes with a drill press is an awful long way from that. Especially it is hard to say someone is "in the business" if no money is changing hands and in general the person on the other end of the conversation is not going to be using your tools. Anyway, the fact that the 80% community has its own whole set of legal issues to deal with is in my opinion MORE of a reason why we need an 80% forum and why the existing "Build It Yourself" forum would then be free of the 80% specific issues and could focus on mainly people who are building from a bought lower. I think there are a lot more of those people and most of them probably don't care to wade through all the 80% threads. |

I had those X2 type mills a long long time ago. The tilting column had a tendency to move on you... If you're going to get a X2 you might as well spend a little more and get the Grizzly G0758. It had it and it's really stiff, it can do .200 DOC comfortably. Only downside is the 8.5" spindle to table height, which isn't enough if you want to do anything useful like drilling (most drill bit + chuck would just about take up that entire height).
I went and got the G0704 instead, same thing as G0758 but the action is a lot smoother. No wonder people love it for CNC so much. |

The problem is, because it's designed to tilt, that design inherently greatly reduces rigidity.
My bracing V1.0 
I cannot explain how much difference this made. FWIW, when milling 80%'ers I run a .300 DOC now at a pretty fast pace. Probably faster than I could do .080 before. I did add a much larger vise at the same time, so that does account for some of the increase in capacity. |

i'm quite satisfied with my Taig DSLS 3000. it's a bit small, but works great on 80% lowers. you can get them used for a fair price. someone just sold a Deepgroove version for $1000 locally. CA_Longshot has been great responding to emails and helping me get setup, so the community is very helpful when reached out to. Without looking at his posts here, i would have never purchased my Taig and attempted an 80% lower. now i want to stack them deep.

You know, honestly welding braces to X2 type machine is overkill. I mean unless you are getting materials for free or have access to welding equipment and know how to use it, it's too much modification for a small machine with limited horsepower and possibly sloopy bearing.
You're better off selling the X2 and buying a bigger machine with better rigidity. |

I mean unless you are getting materials for free or have access to welding equipment and know how to use it, it's too much modification for a small machine with limited horsepower and possibly sloopy bearing. You're better off selling the X2 and buying a bigger machine with better rigidity. They are not welded to the mill, it looks like they just welded the brackets to bolt to the mill. I know I would love to get a bigger mill than I did, but I simply don't have the room to put one in, I have limited area to set things up right now. I know with mine, the brackets were already installed to stiffen it up. |

What I meant was get a mill drill like G0704, X3, Rong Fu type ones, etc. that while is not too big, is bigger and stiffer than the X2.
Personally I hated the X2 because of the column that could move on you (you couldn't tighten it enough because it's got a lot of leverage) and the gibs are a pain to adjust. |

Personally I hated the X2 because of the column that could move on you (you couldn't tighten it enough because it's got a lot of leverage) and the gibs are a pain to adjust. That is what I liked about the X2 I bought, the retired machinist I purchased it from did similar to what has been posted, but he also added two pieces of 3" x 4" angle on the column that bolt through the bench you have the brackets as shown and then they are wider and cut to fit to the bench, so it is mounted to the bench and the two outriggers are also bolted through the bench, it is very sturdy with the back enforcement as well as the column braces. Also the large nut on the back that allows you to move the column has been cross drilled and staked so again, it is very sturdy and I didn't do any of the work and I purchased both machines and all of the tooling for a pretty good price. I was surprised at how much you can stiffen the mill by just cross drilling the large nut and bolt and pinning it. When we move, which is going to be in the next year or so, we will be looking for a place that has an attached cement floor garage and then I will look at a larger knee mill, there is a lot of custom stuff I do on boats as well, as I purchase older boats and restore them. I like the X2 as there are quite a few little dohickies I can mill and with the small lathe, I can turn small parts as well, so it is fun to play with them. Like said, I didn't do any of the work on this mill, I just benefited from someone else's work. |

I'll admit I haven't got into the 80% receiver thing, but I do think it would make a great addition to the site. I mean despite what others may say about some of the asshattery that goes on here from time to time it can't be denied that this is the best place on the web for all things firearms. I think if added it would consolidate a lot of info and make it easier for anyone looking for help on these topics to locate the info.

I vote yes! To the OP or anyone else looking for a cheap "quality" vise, Ive had great luck so far with this little guy in my CNC. I bought two in October and use them both every day, only issue is one of the handles doesnt fit either vise.

Quote HistoryQuoted: 100% legal (maybe not in Kalifornia) I don't see an issue with discussing it. Quote HistoryQuoted: Quoted: I am just guessing here but it's possible a good portion of the 80% community would only like to read what a dozen or so of us are willing to disclose. I understand that an online forum is a broadcast and some may even say we could be irresponsible for offering up first hand knowledge regarding manufacturing. Any thoughts on that? Any laws reagarding it? 100% legal (maybe not in Kalifornia) I don't see an issue with discussing it. Actually CA is G2G, surprisingly, but you must engrave your name, city/state, and a serial number on it for ID purposes. It also has to get registered with CA DOJ or some other state based agency. NJ on the other hand is 100% verboten if you complete the lower inside the state of NJ. They require a state permit to manufacture any type of firearm, not just AR's, and its' a felony if you build your own gun (even a home built gun like a Jaco pistol or a black pipe shotgun). |
