I've been tossing around this idea ever since I started trying to fit AK furniture to my SKS D. Over the past few months I've been slowly gathering parts and finally got to work tonight.
My SKS D know uses and AK47 trigger group.
1.5x3" rectangular tubing
I started off with a simple chunk of 1.5"x3" rectangular tubing with a .125" wall. This size was used as the inside dimension are damn near the same as the outside dimensions of the SKS reciever.
The SKS reciever outside dimensions measure .1252"
A rough lay out was drawn up and I did a rough cut with the torch. In hind sight I should have used the cut off wheel, but I'm stupid. The cut was then cleaned up with the grinder, getting the sides close to straight, etc.
A hole was then cut for the rear locking tab thinger-ma-bob. Seems to hold the new "reciever" well.
Rear locking tab grabs the reciever block nicely
I had previously welded a nut to the gas block in a previous build and this provided a solid front locking point.
Front mounting point
Holes were drilled and the AK47 fire control group was installed. You can see by the pictures that the trigger holes are not straight. the trigger also sat to close to work properly. This is why I chose to do a first try using heavy steel. The fix was a simple as welding the holes shut and trying again.
AK47 FCG first try installation. Note unmodified hammer.

Of course its not as simple as building a body to hold the AK47 trigger and hammer, oh no. The SKS hammer is much longer and shaped very differently. Still, this was simple enough to fix. The hammer was cut flat in the front and a block of steel was welded on. It was then ground and filed to shape. I cranked the heat on the MIG right up and cranked down the wire feed so the welds should be good. the hammer still needs some cleaning up and finally sizing, then I'll think about hardening it or something.
Modified AK47 hammer.
That's as far as I got tonight, not bad for 4 hours work using simple shop tools. I still have to make up a trigger guard and mag catch and mount the pistol group (it's attached with sticky tack for the picture
). The front grip also needs some touching up and final mounting.
The end plan is to bend up a sheet metal lower for a lighter, cleaner, and much nicer looking rifle. With the sheet metal lower I will be using an AK style safety, FCG pins, and trying to rig up a rear trunion and AK recoil spring guide and top cover.
I'll keep you guys posted as the project goes on. Just think, if this is what I can build using scrap metal and simple, every day shop tools, just wait until I've got access to a machine shop! Oh yes.
