Anyways here is some info

you will at least have to mill the rails, disconector hole drilled, grip bushing holes drilled and tapped, mainspring housing slots milled, and various other small holes drilled

They are 4140 heat treated castings

PM if you are interested too much thread crapping...

Lol

I might be interested, I would have to see how much more work a 60% needs than a 80% so I'll be cruising google for answers and let you know then :D

Well there isn't really an 80% 1911 frame out there because of the grey area of how much is really 80% on a 1911 frame....

KTO makes an 80% frame but I think it's $200 or $300, IDK off the top of my head...

yeah and a 60% should be more like 50-60 IMO. i'd be interested if the price is decent.

If you are going to run them on a CNC, could you raise and checker the front strap?

depending on quality that could still be very acceptable i think, especially considering the competition.

Standard 60% frames Were usually running about $25 each, or 5 for $100

don't know if they're still available, will look into it...

There are currently 2 sellers of ~60% castings, bkhose and caspian45 (no relation to Caspian).

-The bkhose casting is made of stainless steel and the caspian45 of 4140 heat treated aluminum.

-The bkhose has the thumb safety hole cutout while the caspian45 does not.

-The caspian45 has somewhat of a slant in front of the dustcover that may need to be cut down, the bkhose is straight but still might be a little longer than spec.

-The bkhose goes for $95 the caspian45 goes for $75.

General instructions for finishing a 1911 casting

1) Measure the thickness of casting. Note the difference between the measured thickness and the blueprint thickness of 0.762". Shave half of the difference from the right side of the frame.

2) Drill takedown lever hole to 0.201". This will be the origin (0",0") for referencing the other holes.

3) Ensure top deck is level. Shave down top deck to 0.450" from the center of takedown lever hole.

4) Square frame using top deck. Drill these holes:
-Plunger tube holes (THROUGH ONE SIDE ONLY) 0.098" @ (1.402", 0.76") & (2.204", 0.76")
-Hammer pin hole 5/32" @ (2.973",0.016")
-Grip saftey pivot hole 5/32" @ (3.368", -0.210")
-Sear pivot hole 0.110" @ (2.602", -0.252")
-Grip bushing holes 7/32" @ (1.937", -0.431") & (3.018",-3.309")
-Mainspring housing hole 5/32" @ (3.750",-3.595")

5) Shave the other side of the frame to bring the thickness down to 0.762"

6) Rotate frame 17 degrees counterclockwise relative to old x-axis.

7) Establish new origin (0",0") at mag release hole.

8) Using a 5/16" endmill, bore the mag release hole @ (0",0") TO A DEPTH OF 0.695".

9) Using a 0.290" (L) drill, bore through @ (0",0").

10) Plunge a 7/32" endmill to half the thickness of the frame @ (-0.227",0") and mill back to the origin @ (0",0").

11) Plunge a 5/16" x 0.050" keyseat cutter @ (0",0") to a depth of 0.110", mill towards muzzle 0.055" to (0.055",0")

12) Rotate frame -18 degrees clockwise relative to top deck.

13) Establish new origin (0",0") at grip safety pivot hole.

14) Using a 13/64" endmill at half frame depth make two passes @ (-0.461",-0.101" to -0.461",+0.101") & (-0.469",-0.101 to -0.469",+0.101")

15) Plunge a 1/4" endmill to half frame depth @ (-0.5035",0)

16) Mill the undercut for clearance of the safety notch with a 0.25" keyseat cutter. Thickness is not important as you can take more than one pass. This undercut starts 0.066" below the surface and continues down to the hammer slot. I used a 0.25" x 1/16" keyseat cutter so I had to make 4 passes to reach the hammer slot depth. Zero the cutter off of the top of the casting and plunge to 0.066" plus the thickness of your cutter at the location we plunged for the bubble (-0.5035",0). The cut we made with the 0.25" endmill also provides clearance for our keyseat cutter. Once at the proper depth (top of cutter 0.066" below top of casting) mill to (-0.512",0) this gives us our starting point. Mill the undercut from (-0.512",0 to -0.512", -0.101") then to (-0.450",-0.101") then to (-0.450",+0.101") then to (-0.512,-0.101) then return to (-0.512",0) forming a rectangle under the surface. Plunge the thickness of your cutter and repeat the sequence untill you reach the depth of the hammer slot.

17) Cut slide rails.

18) Shave down MSH area (I'm not sure of the spec of this part)

19) Cut rails for MSH (again not sure of spec)

20) Cut slot for sear spring

21) Machine frame bed area.

22) Machine feed ramp at 31 degrees.

23) Drill 3 disconnecter holes

If someone could find a way to set a ~60% in a CNC machine and just "press a button" that'd be awesome. I've seen some discussion in another thread about doing something similar with an AR-15 80%.

uhh I wish they were that cheap but of course since someone said they were $25 everyone is going to expect it to be that cheap... and i'm going to get endless pms that whatever price i post will be too much $$$

Anyways here is some info

you will at least have to mill the rails, disconector hole drilled, grip bushing holes drilled and tapped, mainspring housing slots milled, and various other small holes drilled

They are 4140 heat treated castings

but like I said since someone said the $25 number everyone is going to expect it to be that cheap and I am going to get a ton of grief if I offer theses at $100. Like I said above, I wish they were that cheap. anyways, I'll probably let this thread die now.

You're probably thinking of the Sarco "decorator" frames. They were going around this price maybe 2-3 years ago.

Sarco was one source, but iirc there were others, they were less than 80%

I wasn't trying to lowball anyone, just point you in an alternateive direction, you can sometimes get frames pulled from production early by a manufacturer instead of getting purpouse made 80% receivers.

what gray area? 80% are legal . . I'd be down for an 80% frame! only the rails need to be cut and that has been done with a dremel with a couple stacked disks and a 30 dollar router table check it out below

What gray area? I have done research and there is a lot of info out there about how KTO is the only place making 80%s right now because it's an gray area. BATFE does not tell people how much done = 80% so some people run the risk.

If I could afford a KTO 80%, I would do it but I don't have the couple of hundred to spend on one. I'm kinda broke.

BTW sweet setup you got there too, that's a KTO 80% yeah?

Sarco hasn't had them for a year or so by now, and theirs were hit or miss, from what I heard. The price went up for better quality/more complete frames. I tried to find anyone else selling the frames under $80, but couldn't find them in stock anywhere.

i am interested, but without knowing what operations are already done and what are left to do i cant say if i want one at any price, there is no such thing as 60%,80% ect , its all marketing , its either a chunk of metal or a firearm, only diff is how much is done before atf says its a firearm .. so what needs to be done on these (the manufacture should be able to tell you and pass it on to us)

just a guess

slide rails
mainspring rails
fcg holes
safety holes
grip safety
barrel bed/feed ramp
ejector drilled and cross pin hole

any of these operations been completed on these "60%" ?


a good pic would also be nice as i am looking for one that can be cut down to a compact (my current 1911 project would have to have the grip re-welded to cut it down)
