| ive been looking for information on here about 80% lowers and I cant seem to find anything. I searched about 50 pages and cant find what im looking for. if there is one I wanted to find a step by step or some how to's and do's and dont's about 80% lowers. just want some pointers and to do some research before I jump into it. thank you for any help |

Quoted: don't need the attitude. its just the informational threads on here seem to be really detailed and that's what i would like to find Its not attitude. Dial it down a notch or two... I just got a set of jigs myself, and the info here is... not exactly what I was looking for. I found out everything I needed to know on Youtube. For once (and I thing the only time in my life), YT was actually good for something. Chill out. |

IMO the Vader tread was more helpful with anodizing than the machining process.
This is better detail HERE It provides more detail than you really need if you opt to buy a jig and a lower with everything but the fire control pocket milled and drilled. Fire control pocket is Chapter 10. |
You sure have a purdy mill compared to ol' Betsy here

Simple Taig package.. MIll, motor, stepper motor& mounts, stepper controller and Mach... start out about $1800.
But I built my own controller and just picked up the cnc- ready Taig (Only Stepper mounts)... it cost me about $1500. The CAM package I use is CamBam. I am planning to move getting a 3d modeling CAD package...I can export .stl to Cambam.... For more photo of my Taig and AR build see this post Taig Ca_Longshot |

No Automatic Tool change on my baby CNC Mill.
For small projects, I breakup my cnc routines by the tool needed.. So at the end of each routine, it returns to home position. Then it is a matter of raising the spindle(Z-Axis). Changing the tool. Re-Zero Z axis. Now I just need to load and run my next routine... For larger projects... I can program for a tool changes. So when One occurs, it will go to home position. Then Pause itself Now I change the tool, re-zero, hit start.. Ca_Longshot |

go to 80% AR EZ JIG just started mine using a drill press. very sloww but is looking ok Well take it VERY SLOW!!! If you have read any of the threads out there on milling your 80%... A Drill-Press and it's chuck assembly are not made to take very much in Lateral Forces!! This could lead to a dangerous situation while working on your 80%!!! So Take Care.. Ca_Longshot |
