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.

I wish I had the Room for Betsy!!!
But my CNC Baby mill does get the job done...
Not as fast.....with much shallower cuts......

But both machines will get the job done right...and clean!

Looks like a nice clean job you and your CNC mill did on that lower!
Are you doing your own anodizing or having it done?

That one I sent it out to be anodized at a friend shop.
The one I just finished... I will try my hand at Cerakote Paint job...

What did the CNC set-up set you back?

What are you using for modeling & program software?

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

Thanks for the link. Some very nice stuff you build.

Do you manually interrupt the process to change tooling or does it have a auto change head?

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..

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..
