Another boring Saturday morning so off to the shop. First problem I couldn't bend the top rails in so I made 2 halfs. Next I need to make a quick fixture so I can tig weld the bottom joint together.


The tape inside is just for picture purposes.



PS: I need some rails.

Campy

 Global claims (acording to website), that it take 8(IIRC) dies to complete the REC., this is their tooling form Bulgaria??

So far I've compleated 2 Aks from SS. Did mine just like you have done yours. I used .056" thick 316L.
The biggest problem with these is the radius in the bends. Stainless just doesn't want to bend very sharp.
To cure this problem I made a set of dies to "sharpen" the bend. Basicly it just a piece of 2"x2" bar stock with a 90deg. V grouve milled in it. The other part of the die is a 3/4"x3/4" piece of HHS with one corner ground to a .312" flat.
A 12ton hydrolic press "squeezed" a nice shapr bend into the halvs.
I started at one end and slowly moved the lenth of the part. Also I didn't "sqeeze" it all at once. I made 3 passes. This was to halp keep the pieces from warping too bad.
For the welding jig I used 1.250" x 1.000 bar stock with a .060" deep grouve milled in it with a ball endmill. This worked real well with no oxidation on the back of the weld. TIG welded it with 42 amps and got a perfect 100% weld.
I now have stainless AMD 63 and AMD65.
Next will be a Polish underfolder, then an AK74, and then a Romac 3.

looks like fun, but how are you building new guns from the kits that are listed as "for replacement use only - not to build a new gun"

how do you get around that?

You build the "gun", i.e. the receiver, from scratch.  You can then put whatever other parts you need on it; they have no special legal status for a homebuild receiver.

That's just a disclaimer from the importer.
IT DOES NOT RESTRICT AN INDIVIDUAL.
Just follow the 922(r)rules

This is so wonderful :)

I have been looking at 80% AR receivers, I think I will check this out instead, I love AR's but AK's might be a bit more forgiving and less $$$. Is the AMD63 the best bang for the buck for a fullsize AK right now? I saw Interords SAR kits for $119, centerfire's $129 kits, I like the AMD63 kits, minus the forward handle, I wouldnt put it on. Are the kits high quality?

Ok now off to read up on how to manufacture your own receiver...

I have some of the AMD 63's They are excellant.
Call Lois at centerfire she'll do you good.
Beg and Grovel if you must, just tell her you came in late for the group buy and ask If she'll help you out. It's worth a try. And good luck on the build. Take a trip towww.acearms.com/products/index.shtml

Campy  Not realy a sheetmetal guy. I build machine tools. Currently I'm building the machines that make the parts for jet engines. Both comercial and military.
To build these you have to be a welder, machinist, sheetmetal man, and a S.O.P.E.
That last bit of info is to give you something to think about the next time you fly.
