P80 Lower Receiver Not For The Amateur Reviewed by Marion Harris on Dec 12, 2018   5 out of 5

I had never tried milling before and the video makes it look easy. I bought the wrong drill press to start with...it was a 10" WEN bench mount press. Once I added an X-Y vise the vertical working space was greatly reduced.. After installing it into the chuck the milling bit hung about 1" lower than the top of the jig. I tried to outsmart it by inverting the press table and I gained 1.5", but no matter how I tried to shim it using a torpedo level the X-Y vise would not level in both directions on the uneven surface. I then resorted to adjusting the jig by raising it about 1/8" in the rear as near as to true bubble as I could get it and then tightened the vise very hard. I started milling and it went well, but raising the jig in the vise didn't work out and I broke through the floor of the fire control group pocket. What part I did get done looked really good with smooth sides and smooth at the bottom of the pocket...until I broke through. I got discouraged at that point and rather than buy another drill press I purchased a pre-milled lower at the local gun shop. However, I do firmly believe that if I had the correct height drill press I could have accomplished the task and milled the pocket properly. The milling part was not as hard as I first thought so my difficulty was in my initial setup not being attainable with the press I bought...I wish I still had my old Sears floor mount press and it would not have been a problem. So, my suggestion for the first timer is make sure you have the correct equipment with plenty of height adjustment to compensate for the vise.
