1911 80% frames?




If I were to try and build my own 1911 from a kit with an 80% frame, what tools would I need to finish the frame? I have heard just a Dremel will work, but I have my doubts...

Would I need an expensive metal lathe or mill?

I'd love to meet the dremel jockey that can make a non-caveman looking 1911 frame from an 80% casting.
That kind of steady hand should belong to a brain surgeon.

I think you'd need an expensive mill. I don't think there are any lathe operations on the frame of a 1911.
At the very least you'd need a good drill press to make all the pin holes.

How about a Caspian or Essex 100% frame?
I think Armscor may be selling bare frames through Sarco for half the money of a domestic frame.

There have been several 80% frames completed successfully with just a dremel. ALL of them involve some type of jigging or fixturing. I have seen the dremel router table used, a "fence" built from metal to locate the dremel, and the 1st one I saw done with a dremel the guy used the drawer slides from regular draws to run the frame true to the cut-off wheels in the dremel. One guy did a frame using two or three hacksaw blades soldered or welded together and then cleaned it up with a Brownell's 1911 rail file.

Here are some pics I found of an 80% build using a dremel router table. HTH.





Here's a link to a recent post on the Roderus forums that might also help you. Good luck ! !

"just a dremel" and "jigging or fixturing" are worlds apart.

I have seen a couple of WECSOG 80% 1911s and they were both pretty and functional. But as a WECSOGger myself, even I would have to admit that the Dremel is not optimal. These days, I use my mini mill and a 0.1180 Key Seat Cutter with a frame jig.

There are no holes that need to be drilled or tapped in any of the 80% frames that I've seen. Just the rails need to be cut and fitted to your slide. I've never used the dremel method for cutting the rails -- and I am not recommending it -- but it has been done by several DIY'ers with excellent results. YMMV . . .

Here are some more pics and another thread that details the procedure.

Guys, that is so awesome and I am thinking of giving it a try. How sick is that, making your own 1911-A1!

i agree the Dremel method is creative, but it would be much much easier to use an inexpensive drill press, a machinists vise and a keyway cutter to do the rails. I have buit a couple of 80 percent frames and this is the way I did it before I had a mill. The dremel method looks like it will work, but it will require ALOT of precise finish filing to run true. Don't forget that just because it works, doesn't mean that you should do it that way. Also, the only difference between a crappy 1911 and a truly nice 1911 is the parts used to build it and their fit. sssnake

That was going to be my question. Now that the JBTs have shut KT Ordnance down, where else can 80% frames be gotten (or will posting that online bring the stormtroopers down on them, too)?

www.thetanneryshop.com

also has them as well as 80% recievers for ar-15. I think JT ordnance had something else going on that brought out the ATF ninjas. Don't quote me on that, just something I heard..... sssnake

I was on a website the other day that had 80% frames for just under $100.
Why pay arsealline $192 when you can get a Caspian frame from MidwayUSA for $175 or an STI for $240.

I'm still thinking about it, but Essex frames are so cheap and they are cast and machined with much better quality than in the past, I was thinking of going that route.
