- Machining a AR-15 lower receiver. This is setup 1 - of many. All of the CAD / CAM was created in Fusion360. (Fusion360 is pretty awesome if you haven't used it before you might take a look) If anyone would like feeds and speeds just let me know...

Great video. Did you ever figure out the holder for the other side?
This is the first time i see a tormach mill being used at a faster feed. Doesn't look bad all. Great video! Did you mess with the coolant pump? You seem to get more coolant than other people
#fabian I sped up portions of the video to hopefully make it less boring in parts. The beginning is playing at a normal rate. Watch the section of the video from 3:28 - 4:28 the video is playing at a normal speed and I am pushing the limits of what the Tormach can do. If you watch the video from 2:12 and listen to the motor as it turns the corner to machine the Y axis that little bit extra material causes the machine to bog down quite a bit, so I would say that feed rate is about max for the machine, end mill, etc. Note that section of the video is sped up but I am machining at the same rate as 3:28 - 4:28. I am just trying to point out that what you see in 3:28 - 4:28 is really close to max rates..
About the pump- Yeah I removed Tormach's pump, coolant tank and the flexible cheap knock off Loc-Line. If you look in the aquarium section of ebay for Loc-Line you should see the stuff I'm using. I replaced the pump with a Becket outdoor pond pump (Beckett 7107910 Pond Waterfall Pump 600gph). A 27 gallon storage container was used for the reservoir if you have a Costco nearby they might have them for $6-7. They are black with a bright yellow lid and very rigid. Make sure what ever you end up using has very rigid sides otherwise it will bow out when full of liquid and the lid wont fit properly.
Hope this helps.
Nice job
thank you
Great video! What Tormach model is this?
Tormach PCNC 1100... Are you trying to decide between the 1100 and 700?
Anyone know what the price is for one of these machines?
Where do you get all of you aluminum stock from?
That was a hunk of aluminum bar stock I bought from our local scrap yard... If I remember right I paid $70 for a bar that yielded enough for three blanks after cleaning and squaring. There was a 0.5 inch deep cut mark I needed to work around that was already in the material.
I'm trying to decide between the Tormach 1100 or the 770! I'm going to be manufacturing AR 15's, Cerakoting, and Selling! (07 FFL)! I'm not looking for a major production rate but I see that this is the 1100 model. Can you advise what the production time would be on a lower receiver with the way your are operating here? Also would there be a major asset to having the 1100 over the 770?
The 770 'x' and 'y' travel is too small for this job imo...
1100 workarea: 18” x 9.5” x 16.25” - - 770 workarea: 14” x 7.5” x 13.25”
Honestly, I bitch about the travels that I have now, so I really can't imagine going smaller. Rigidity.. I could see rigidity being problem -even more so than it is with the 1100.
@@oohookoo you definetly not recommend the 770 m or mx for this job
thanks for the info. Yeah I noticed the spindle winding down as it turned. you still machine faster with a tormach than others that post videos on UA-cam. I'm looking to buy one myself but I wanted something that is a bit faster. but you may have changed my mind. thanks
Cool! I'm anxious to see how your going to fixture the other sides. I have basically the same CNC setup as you
#Mark LoL so am I. Right now I am working on a soft jaw that should work, but I haven't had time to machine it yet.
I got the idea from 'Machining the AR15 Lower Receiver Forging' by Ray Brandes and if you haven't already you should check it out theres alot of good info in it. Heres the link www.lecreg.com/P4x4/ARblank.pdf
can you add a direct link to the video?
I just bought a 770, and am looking to do this same project myself. Would you mind sharing your feeds/speeds, as well as list the tooling you used to mill this out? I'm very excited to tackle this. Also, do you have a file for either SprutCAM or Fusion 360 that you'd be willing to share? Many thanks.
I don't know why I'm just now seeing this comment.. So how did it go?
@@oohookoo lol you kept me in suspense there! My biggest problem was the magwell and the angled holes. Need more fixtures to do those reliably. I also used a 4th axis which I think is the way to go. Unfortunately the whole project is massively expensive compared to large scale production. Hard to justify without offering unique customization. Are you planning on doing more AR receiver videos?
@@devinmorton1846 4th axis is cheating lol Your absolutely right about it being an expensive project and 'unique' is the key to anything close to compensation. Are you talking about that long drilling operation on the bolt catch? Btw I'm so glad you actually attempted this. I am thinking it might be fun to expand on this video what do you think? any suggestions?
@@oohookoo absolutely a great idea! I'd love to see an updated video with how you did it in a vise.
Yes, the deep bolt catch hole is tricky but the angled/threaded hole for the grip screw, and the buffer detent hole are tricky to drill as well. I'm considering making a 4th axis jig to spin the receiver so I could do both these holes on one setup. But again... time and effort.
Yes if you have time I would absolutely love to see how you finished the backside and positioned the receiver for these awkward holes... thanks!
Okay I gotcha.. yes those holes are tricky let me see if I can't shoot some video over the holiday.
Hi, I just bought a tm1p and am trying to find a file to run my own. Any advice ? also how did you finish the mag well?
check out CNC guns he's got free gun files
My advice would be to find the patent blueprint drawings and model it yourself in Fusion 360 or whatever software you have. Going from a simple drawing to finished part off the machine will force you to think about every aspect of the process and make a decision (right or wrong) in order to progress forward. This process is invaluable.
how can i get that CAD CAM? please someone tell me
One of these days I'm going to get a much more indepth video posted of the complete process. Until then do what I did and model it in Fusion working from the publicly available design patent.
LOL oooops @2:18, little heavy cut there! Bet it made you pucker
Just for a second =)
Finished product?
I am filming a much more in depth video for the subsequent operations but it's a lot of work...
Can this machine make a ar15 upper from scratch
Everything except the barrel can be made on a 3 axis milling machine. It doesn't matter if it's a CNC or manual Bridgeport style knee mill. That being said I haven't personally made an AR upper on this one but I have made plenty of other shit.. It really just comes down to fixturing and tooling or 'how your going to hold it' and 'how your going to cut it'.
M16's were first made in the 1960's so only 60's tech is required here. It would be a fun little project and you would defiantly learn a lot in the process. If you get stuck just ask.
Keep in mind what's possible and what's profitable are two different things.
How did you flip over?
I designed a fixture to hold it in the vise
@@oohookoo why didn't you show us in the video it would be cool
@@lalmuanpuiijahau7531 It wasn't in this video because I didn't have it figured out yet (when it was filmed). I will try to film another part 2 for all the people who are curious.
@@oohookooyes, it should be filming again 👍
One question what's that cnc machine name?
How can I get your service for my project
What do you need help with?
@@oohookoo 3D CAD file/ design for my lower.
Have you already started and need help or ground up? lWhat's a good email for you?
