Here is the latest project.

For anyone w/ access to a CNC machine I have posted the CAD and CAM file here: http://a360.co/1JeL1pq

If you haven't tried Autodesk Fusion 360 - its great. The model is based off of mik's cad file on grabcad.com.

I extended the dust cover to full length and added tactical rail. Also some of the dimensions were off a bit particularly the frame rails had to be fixed.



Here is the block of 1.5" square x 8" 7075 aluminum:



After the first few operations:






Flipped to machine the Right side of frame:


After top is machined:


Bottom is machined and final product (I still need to drill plunger tube hole and square off hammer area:

Nice.
Did you need to make any custom jigs for it or where you able to just use the vice?
also
What edge finder is that and how does it compare to a mechanical one?

Xfer42:

No custom jigs - just std parallels and the vice!
For the Plunger tube I am using a right angle bracket attached to the table and the frame clamped to it vertically.

I use a passive electronic probe (wildhores innovations)
A good probe is key as I zero on the slide stop hole and sometimes of the grip screw hole.

Spyde12 - the actual machining took about 6hrs total. However I have spent a month learning the cad/cam programming, and I did screw up about 6 times before this final product. Fortunately aluminum is cheap!

Screwing up and learning is the way to go for us DIYers

It's a 3 axis Novakon Pulsar mill - similar to a tormach but mine can rigid tap. Here is a video of it roughing.
