Hi Dave, I can't sit down now and tell you all the things that you'll need to do to build an AK. I don't have enough time tonight. I will have time over the next two months. If you want to build one, there will be a lot of folks who can help you get through the process. For rivets, the rivets you will probably need to do are the ones that hold the trigger guard on. They aren't too hard to do. All you need are two square end punches, a vice and a big hammer. No press needed. Clamp one punch in the vice, push the rivet thru the hole, ( don't forget the safety lever stop ) and bash it flat with the other punch. No big deal. You can also find a way to screw it on and skip the rivet thing all together. I have heard of others doing this, but I'm set up for rivets on the handguard and it's easier for me this way. You'll need a drill press and your buddies press, a couple of pieces of steel about 3/4 inch thick to build a clamp for the barrel for the press, taps, screws, and probably a dremel tool, and you're in. The process is quite straight forward if you go slow and don't get into a big rush.
The Inter Ordinance kit is re-finished. It looks new, but I cannot tell you the barrel is good. Most have 50% of their life left, but it probably will not be a tack driver. Few AK's are. But first get the kit.
