Polymer80 PF940C Lower Frame Milling Instructions Tutorial Video Part 1

Hey, Andrew here with Omaha Outdoors; in our last video about the Polymer 80, we unboxed it, we took a look at what it would take to make it into a pistol – that is, into this – and in this video we’re gonna show you exactly how to do that. So, pretty simple, it’s not super complicated. First thing you’re gonna need to do is drill out three holes, and they are so nice as to provide drill bits for this exact task. Now, I wanted to do this with the simplest tools and methods possible so, although they include an end mill bit for milling off this area, and here –which we’ll talk about in a minute – I decided to do this all by hand; so I have a hand drill, you just insert the drill bit in there, tighten it down, attack. Again, three holes: two small, one large. You wanna do each side individually so, you don’t want to drill all the way through from one side to the other, cause you could be slightly crooked; you wanna do one side, very slowly, making sure that the drill bit is perpendicular to the surface of the jig. You wanna make sure the jig itself is plant tightly, but not too tightly, in a vise, so that those holes are placed exactly in the frame where they need to go. And, again, you wanna go slow, you wanna make sure the drill bit is straight. This was a really simple process for me, and I don’t think it took more than 5 minutes to drill all these holes by hand. Once that was done (set those aside) I moved on to files. Now, files are not in their instructions but again, I wanted to do this all by hand and I wanted to see if I could do it very simply, so I removed these top tabs – which they nicely label “remove” – with a file. I used a large file, making sure to go only in one direction, and then I went down to a smaller (or finer) file, when it was time to do some detail work. Finally, there is this area you have to remove, so that the recoil spring assembly can sit inside the frame – well, in the slide inside the frame. For that I used a round file, and again, I went slow, took my time, only went in one direction, it was very simple, for both the filing and the drilling, I would say that it took me about 35 to 40 minutes to do all this work. And when it was done I was left with this: which is a pistol frame that is 100% – it went from 80% to 100% in about 40 minutes – and now it’s ready to accept mostly stock Glock parts – there’s only a few proprietary parts which they include, and we’ll cover that in our next video.
