CNC Router 80% lower

[porterdavid98]

Can anyone point me in a direction to talk to someone who has successfully used a CNC Router to machine a 80% lower? I ruined one end mill and one lower so far.

What brand router are you using? Manually writing G code? Any CAM software or controller capabilities for simple pocketing?

If you're using a jig from somewhere like 80% Lowers, or similar, and using your standard router, you have to go slow and be patient. Having done one this way (which is extremely cost effective compared to an actual professional machine) it takes some time, but in the end pays off if you aren't willing to spend the serious coin to get a CNC machine. Also, from a legal standpoint, if you do not personally machine the lower yourself, you have to have the person doing it serialize the lower and do the proper transfer.

Check your feeds and speeds vs the metal your cutting. If you have 70 series you need to go very slowly and make very small cuts.

Light cuts with wd-40.
Take your time.....

I would also look into the 5D Tactical jig. That thing is pretty amazing, but certainly not cheap. They have a video on their YouTube channel and they knock out a lower in about 30 minutes - with a router.

That's where it's at! I like the 5D Tactical jig, but I don't like the price tag.

Holy copy of the 5D, but better.

That's funny.

I finally got around to making a machining fixture to use on a DMG 5 axis mill, one set up and 18 minutes to complete.
