The older jigs that were sold by The Tannery Shop were as close to that as you were going to get. They are LONG gone!

I think that is called a vise

I have one of those and it will probably get you from maybe 40%. There are still a while bunch of operations necessary to get a 0% forging or casting up to an 80% that it doesn't accomodate. |

Quote HistoryQuoted: I think that is called a vise Lol But that would require the use of math and stuff It just seems like someone could include a few different plates you switch out to get it done. |

Looking at the drill press jigs it seems like someone could make one. You want to use a drill press to mill a 0%er? |

Quote HistoryQuoted: Lol But that would require the use of math and stuff It just seems like someone could include a few different plates you switch out to get it done. Look at an 80% lower and all the milled areas that are already done. There are quite a few of them. The old CNC Machining jigs that the Tannery Shop sold for the old style 80% lowers will probably handle 10-12 of them. There are still at least a dozen more that it doesn't facilitate. It is certainly true that someone could made additional jigs for all of those things. But I don't think it would be just a couple more plates, it would probably be several whole individual jigs. The operations that would need to be done are on completely different surfaces. If you're really interested I could make up a list of what the old style jigs can do and what would still need to be done. I'd have to sit down with the jigs and an 80% lower and work it all out. |

Quote HistoryQuoted: You want to use a drill press to mill a 0%er? That would be a horrible tool for most of the operations that need to be done. Like decking the top surface of the lower? Truing the rear surface where the buffer attaches? Jigs could be made to do those things with a router, but even that isn't really the best for doing large surfaces. |

Quoted: Looking at the drill press jigs it seems like someone could make one. I mean it wouldn't have all of the contour of a standard lower, but would probably work. I am pretty sure Bridgeport makes one. For the budget minded you have Enco. |

Quote HistoryQuoted: IKR? I couldn't even imagine it. Dude probably has a Harbor Freight mini too, ha. I have one of those 8" HF drill presses someone gave me. It is barely adequate for drilling holes. I also have one of the big beefy HF drill presses. It is much sturdier and tighter and more precise than the low end one. It is pretty adequate for most hole drilling. But I still would never consider using it for milling a lower. |

Found a 0% jig for you.......
 But the price of 0% receivers is quite high, not to mention hard to find these days.

Quote HistoryQuoted: My Zero Percent Project and after all that work, it lives life under my can cannon. Impressive and nice work. But I was thinking something like take a chunk of aluminum or wood or whatever and make a lower. Of course i guess getting a CNC mill might be the only way. |

Could be done on a manual mill, just more work & figuring out how to hold things,
especially if it doesn't have a DRO. About the only thing special you would need is the tap for the buffer tube thread. But without some formal training, just buying a milling machine, will most likely end in scrap. I suggest to everyone that wants to get into making their own parts, firearm, automotive, etc., is to find some local vocational school that offers basic machining courses, and take a couple of semesters, and buy some quality measuring tools. |

Of course i guess getting a CNC mill might be the only way. I'd say from a billet would be easier. From a raw forging, it only looks like the basic shape. Nothing is flat, straight or square. Got to about the middle of page 3 on my link above. I made a trigger jig. Wouldn't take much more effort to make a functional lower |
