I have an AK74 brake that my friend made for me out of cold roll. He used a Bulgy AK74 brake to get all of the dimensions, and made it on the CNC machine. I ordered my threaded Romanian 22mm FSB from K-Var, and the only thing needed was to thread the brake itself.
I know absolutely jack squat about machining, threading, etc. All I knew was that I needed a tap for 22x1.5mm right hand threads to get this project done.. I called MSC, and ordered a tap. I did not know the difference between a D3 tap and a D6 tap. (I do now.) The D6 tap that I ordered cuts deeper threads than the D3 and so is a little loose on my threaded FSB. With the break screwed in all the way on my FSB, even with the spring loaded detent pin in place, it has a slight wobble from side to side, or up and down. It is probably less than 1/32" of wobble.
My question is, can I use some sort of loctite to illeviate the wobble.Or, will it be okay to fire the rifle with the slightly wobble? I am sure I could use plumbers teflon tape to stop the wobble, but that would probably melt. What do you guys think I should do? The muzzle brake looks just like the Bulgarian AK-74 brake, and I can't wait to get it gunkoted and installed, and give it a try
Thanks as always for your input.
