Have fun with it and study the www info first.I've got a couple questions on a first build I'm working on. I bought a used Polish parts kit, less receiver and barrel, from the Sportsmans guide website, an 80% receiver from Henderson Defense, and a phosphate finish barrel from Arms of America.
1) Would I need to sand/remove the phosphate finish from the barrel areas that press into the front trunnion, the front sight block, the gas port and the front sight before installing these parts?
you can use emery paper in 120 grit etc., to shoeshine the journals. But try the parts first for size.
2) The barrel does not have the pin areas cut/drilled; would a drill bit work in cutting these? I'm worried about the bit walking or being moved over as I'd start drilling on a rounded surface. Any suggestions on how to drill these out.
drill bits work but ideally you need undersized bit ad then ream to finish. Stabilizing the work to the cutting tool is the important part. A drill press vice etc. The bit will not wander much the components are hard and the barrel is soft.
3) I've got the rivets for the build, any suggestions on where to start first and in what order? I'm thinking in this order: center support first, then trigger guard, then front trunnion, then rear trunnion; how do you go about with your build?
there are build "how to" in the stickies above and Google, U-Tube and the www have thousands of pages on AK builds.
4) Options for anti-seize compound for the barrel and other parts. I don't have anything like this locally and would have to order through the mail or air freight; would low-temp grease work or is anti-seize compound better?
oil of some kind will work as a substitute. The more important factor is making sure the journal OD and component ID are within a interference fit range of .001' +/-., not overly tight or loose. This takes a measuring and a "feel" when using a press. There is considerable deviation in component and barrel journal sizes. They are not constant and often require "fitting"., by lathe or shoeshining with emery paper or knurling if undersized etc
I'll probably have more questions as I continue this build. Thanks in advance.
