Anybody have any CAD Drawings? - Page 3

Oh, right, right.

Then, yes, you'll need taps. But if you leave a bit more material around the feedneck, you can use AKA threads. AKA feednecks are 15/16-20, .9375" major diameter (well, the AKA's Viking feednecks are .910, but I've heard it from reliable sources that the .9375 works, and aftermarkets tend to run nearer .93 anyway) whereas Angel necks are M21x.75, or around .827(53/64, about 13/16)-34.

More easily available, but the finer threads are more prone to damage.

Plus, you would only need to buy the one set of taps.

On the other hand, you may not have to adjust the measurements. Bushmaster/Omen feednecks are 13/16-32. Still a tad tougher than Angel threads, and you can actually find them in the US for under $95. Heck, I couldn't find even find anywhere overseas that will ship here with Angel taps, so Airsoldier and perhaps MSC would be your only sources.

Impulse/Ion feednecks cluster around eBay like rabbits around Uncle Bill's Carrot Farm and Viagra Factory, but I have yet to find out what threads they are.

EGO necks are almost as common, and use a double-clamp method--they sit around a 'stub' press-fit into the body, and clamp onto that. Probably the easiest way to go about it, if you can't thread-mill with your CNC or just hate tapping. I have one on the way, and can measure it if need be. It looks like it will be a godsend for those of us with old bodies with press-fit necks that don't want to cut threads into it. Or can't, like with Rainmakers' stupid .015" material behind the neck.

Whew.

We need an exhausted smilie.

Thanks for all of the info, guys. But yeah, I'll be making it from scratch. And I have to have pics for the presentation I put together for this. So as soon as I get started on it, I'll post em on here before anywhere else.

I already have an adjustable Cyborg feedneck and I've measured the threads and it's metric, so my mentor believes we can tap the body that way.

Also, I know you guys aren't going to like this part but it'll make it a little easier. Instead of 'cocker threads, I'm probably going to use Spyder threads because it's metric and a little bit more common tap.
And by the way, Looper, could you elaborate a little bit more on the tools used for the C clip slot? Do you know where a picture of that kind of tool is? This is why I'm doing this project, so I can learn this cool stuff

quick.spyder · 02-04-2008, 10:28 PM

Anymore ideas? I really do appreciate 'em.

xmagterror on AO sells slug bodies he makes.

Thanks, cougar, but I'm not going to be making a slug anymore. It requires more than the shop can provide. I'm just going to machine a 'Mag frame that I designed.

Thanks, guys.

Just tell your metor boring bar, they'll know what it is.
Just in case:

You'll probably want to grind your own for making that slot, or maybe use an internal threading tool to do it.

Thanks,
David

Well, I'm not making the body anymore so I don't need the part anymore. He showed me a couple of boring bars. He said he didn't have one that would fit inside of the body. Thanks a lot though.

Wow I forgot about this thread. Anyway I have an update. I've done all of CNC milling for the frame and all I need to do now is a couple of screw holes and tapping.

I'll post pictures later if people are interested in the process. If not, sorry for the necropost.

cougar20th · 03-27-2008, 08:37 AM

Id be interested to see it. Sounds cool. Id love to make my own stuff. Just dont have the equipment.
