Polymer 80 SC build


#1

My latest video looks like it will be more of a “this is why everyone uses a Dremel” video instead of a “this is how the directions tell you to do it” video.


#2

Eeek.

What happened?


#3

End mill that they send is too short for the Jig. I said screw it and milled that out anyway to see how bad things would get.

Polymer80 Tech Support has yet to get back to me on my request for comment.


#4

Maybe I’m missing something, but the pic above is not a link to the video for me. And when I go on full 30 and search the ‘theroguebanshee’ nothing comes up either. How can I see the video?


#5

No video yet. still working on it.


#6

Ah. Well that explains it!


#7

Now that I cannot build a semi-auto in CA, all I want to do is build one.
You guys are not helping.


#8

I have several of these that I have yet to start.
Thanks for the heads up. :+1:


#9

For all the builds that you filmed and made me jealous…

I love the smell of curling metal coming off a 1911 frame going through my Matrix Precision rail cutter in the morning :slight_smile:
But seriously… I feel for you brother.

@ArmedEyeDoc just skip the mill bit and go directly to Dremel. I calculated out the speed of the end mill to be 7800 RPM, my drill press tops out around 3500 RPM. I got a lot of chatter and really wasn’t happy with the cut. I ended up finishing off with a Dremel anyway.


#11

That is so ridiculous. “The right to bear arms shall not be infringed.” I guess that means something different in USS-Ca?


#12

For that step of the process, use a dremel to rough it out, then a coarse round file to get it close, and finish it with sandpaper wrapped around a dowel or rod of appropriate size.

For the tabs on either side of the top of the frame, I use a dremel for a rough cut, then ‘whittle’ the rest off with a #1 exacto knife.
