Nice!
I'm excited to tinker and share my results View Quote Color me very curious! I'm always skeptical of claims regarding small and (relatively) inexpensive machines, so I'll be very interested in seeing what it turns out. Honestly, my guess is that the last year since they took your money has likely been ironing out bugs, so hopefully it works very well. I'd also like to see what other capabilities it has. It's a bit small for any of my needs, but still could be an exciting little machine! |

Out of curiousity, what do these sell for? I see them mentioning it being cheaper then 1500, and them taking a $250 deposit, but don't see a price anywhere on the site.
I purchased a 12" Wen drill press for doing lowers, but am thinking about returning it, and getting a HF mini mill for a few hundred more.. |
|
I think all said and done $1250… I think if you want one now it's closer to $1500. Too much.
I do hope the gcode isn't terrible difficult, I'm an engineer at heart with a lot of programming and engineering background, so it would be fun after learning it better to go a little off book and see what it all can be used for... At this point I wouldn't give them any money unless they have a proven lead time of less than a couple months, their communication has been pretty terrible. |

They're office is literally a 30 second walk from mine, found out by accident because the mailman kept delivering to the wrong address..

A dedicated CNC machine just for 80% AR lowers. View Quote View All Quotes View All Quotes It's a small CNC machine thats 1st program is to make ARs. It is expected the 2nd released program will do 1911 frames. It's not a dedicated machine - it's just a small CNC mill. |

... I've been told it only works on 80% lowers with the rear takedown already milled out... These do not have that... still seems odd the way it behaved, but that may explain it... I don't recall reading that, but it is in the faq on their website I see now... Feeling kind of like a retard now.

Yeah, they have a software patch evidently, but supposedly State Dept won't let them send it out, claiming it would be an ITAR violation. But given you just got the machine...
Sorry it didn't work for you. Kudos on getting one. I'd love to be able to afford that poke in the Salesman-In-Chief's eye. |
|
I did buy some 80%s (which are again all almost sold out and overpriced as shit thanks to recent events...) With the rear takedown milled, I'll update with one of those as I should have used...
I'm wondering if I can just use a drill press to simply drill out the take down area then use the GG after... Seems like the GG should be capable in some fashion or another mill the rear takedown on its own . I still have two of the lowers like pictured... |

View Quote I've used an updated program for the FCG pin holes and safety drilling. In order to use, one has to run the machine for milling the FCG using the original software, then once that process is complete, close the program and restart using the new program. It's a shame that the promised GG forum is inactive due to the ongoing legal challenge. The lack of immediate technical support from GG is frustrating to say the least. With all the machines in the wild it would be extremely beneficial to have a "gathering place" to discuss issues. I've had multiple email exchanges with the GG group solving issues, but it's been an exercise in patience. |

View Quote What you suggest seems realistic if you can duplicate it dimensionally. The machine needs the pocket to get to the correct depth for each run. ETA, Did the binding damage the machine? I crashed a bit because I got complacent between steps and my spindle had a pronounced wobble which required a return to the GG shop. You can set up the machine empty and run the just the warm-up to observe the mill for wobble. |

Op looks like your FCG pocket is off center too. Is that the case?

I'm less than impressed for the money, imo this thing is not young enough to be having growing pains.
That kinda cash ought to have a push button and a completed lower pops out button lol... Hope they get it worked out in software, I could use a little CNC box for other stuff too. |
|
That sucks. I'm nowhere remotely close to being a machinist, but form my limited CNC experience (very limited) it sounds like it's plunging too much.
Is that 7075-T6 or something harder? I like the idea of such a machine, but $1500 for a single-purpose CNC machine seems to be too much, especially since it won't thread the receiver extension. I'd rather spend a little more money and get a larger general purpose machine. But I really hope the bugs get worked out of this machine? |
|
As rough as your cuts are I'd say it's running too fast and your piece is vibrating/moving during the cut.
Aluminum can smear and gum up if you put too much heat into the cutting process. Can you slow the RPMs of the cutter head or use some cutting fluid? Is the unit capable of supplying cutting oil? |
|
It plunges too much because that area is supposed to be milled already... I'll try it again with a lower that's supposed to be compatible when I can get one in a couple days.
At this point, it's user error :( |

The GG is for those that want an out of the box solution. I like it, I wouldn't buy one, but I can see it's purpose and it fits the bill. Hopefully they get all the issues ironed out. I'd like to see these at every build party, range party and social gathering. It would take a bit of youtubing and ebaying, but for $1500 you could easily build your own cnc mill capable of turning mass quantities of 80%'ers into fully functional lowers.

I honestly can't say I'm surprised at the issues you're having. GG is not really a mill; it's a tiny CNC router in a box, and it behaves as such. There's not enough mass to dampen vibration, especially trying to run router spindle speeds.
For anyone who'd been thinking about this, be advised that you can CNC the little Harbor Freight/Seig/LMS/Grizzly mini machines for not a whole lot more. ~$600 base machine, and about another $1,200 for all the stepper motors, drivers, ball screws, pulleys, belts, etc. that you need. They'll be much more flexible and capable. I like the idea of such a machine, but $1500 for a single-purpose CNC machine seems to be too much, especially since it won't thread the receiver extension.

I haven't seen a respectable, serviceable 3 axis CNC mill go for less than about $7k, with small VMCs starting around $12K |

That depends heavily on one's definition of serviceable and respectable with what one can get out of asia these days for so (relatively) little..
As usual, one can go cheaper if they have more ability/patience/smarts and still get good results. That stuff's doing nothing but getting cheaper and better though. I've seen more than a few chinese mills advertised with pics of AR lowers prominent in the advertising already, they aren't stupid or un-business minded. Give em time.. |
|
I'll be honest...
For 800 dollars you could buy a Grizzly mini mill and finish the lower that way, and it will come out looking a LOT better. The cuts on a 80% lower aren't that complicated... you shouldn't need CNC unless you are going to be mass producing it. How much does the machine weight? If it's really light (as in under 50lbs) then it should be taking .005" cuts and advancing slowly. This means it takes a long time to crank out a lower but it will also mean the surface finish won't be so bad. The spindle RPM should also be around 15,000 RPM, using 1/4" carbide end mills. The lower in the photo looks worse than someone using a drill press! |

Agreed, you can get similar results w/ a router/jig setup. But the intent is this is like a bread machine - it doesn't give you the best bread, but you don't have to mix it & knead it yourself. For folks that have the Ghost Gunner, would bolting it to a heavy platform, or sandbagging it in place help dampen the vibration? Can it be programmed to run @ lower speeds or take shallower cuts? |

That depends heavily on one's definition of serviceable and respectable with what one can get out of asia these days for so (relatively) little. View Quote Shit, I was talking used CNC knee mills with functional stepper motors that maybe only require new drivers and a CAM computer to run them.

Do you have a link showing how to retrofit a HF mill for cnc? View Quote Google is your friend, lots of different way to do it. The kits will be more expensive than making & sourcing stuff yourself, but easier. Here's a video to get you started: https://www.youtube.com/watch?v=niVLBF1D5Wg |

What I don't understand is, if you are only milling out 80% Lowers for yourself why spend the money to go CNC?
On a basic Sieg X2 you should be able to finish an 80% lower in around an hour. |
