A little something in the works that may need a bi-pod

MikeBlack47 · November 29, 2020, 1:44am

Well something came along my way that couldn’t be passed up. So I snag it while I could,

For some of yall here it may not look like much but, it is a Yugo RPK parts kit. Covered in the most stickiest package grease I’ve ever had the pleasures to put my hands on. This was definitely a latex glove job. It a all matching kit but I’m going to have to use a blow torch or oven to get this stuff off. parts are on order so I hope to have this series going for everyone here and to be entertained with.

any tips for getting cosmoline of your kits ?

Soak it in gas and use a pressure washer that is how we did the sks in the 80s.

My Mosin Nagant had the usual cosmoline, but sounds like your Yugo has much more. I poured boiling water over everything to loosen it all up, then I left it all to soak for almost a week in a mixture of trans fluid, acetone and mineral spirits. That worked pretty good for me.

diesel
soak the metal / wash the wood

Jeff300 · November 29, 2020, 3:00am

this is what I would do.

Cosmo is a heavy hydrocarbon. Anything lighter should remove it.

Diesel works well on the metal.

I do exactly this. This is how the people who make cosmoline remove it.

Well it looks like it’s going to be a kerosene dip today

MikeBlack47 · December 14, 2020, 4:02am

The claim portion of the project went very nicely. The kerosene stripped all of that stuff off melting the cosmoline away and after that I bottle it up maybe another project down the road.

This is the final result of some hard work and some TLC. The parts all nice and lube and clean a very start difference and as you can see in the previous photos that was a second rinse on parts that get all this brown Darkness so I don’t know what they did for cosmoline or a second dip but man it was thick and grimy

A slow process de-milling a kit, slow and steady and not egg hole any of the components. Broke a bit on a worn out rivet. But that is the price you have to pay to get the job done right.

I’ve found that still doesn’t guarantee no boogers

MikeBlack47 · December 21, 2020, 3:32pm

This is very true so far so good hear it as I said before using a End Mill to get the cleaner cuts for the rear trunnion and front trunnion. It is a proven method so I’m not going to try to fix the method if it ain’t broken

MikeBlack47 · January 5, 2021, 1:35pm

This was a bit fun working on this at the shop. A lot easier to use a End Mill then it is to Dremel and a drill gun. On a side note for anyone interested in building, using carbide bits is a lot more effective than some cheap Craftsman’s from the hardware store locally. Buy once cry once as they say. I broke two bits trying to do it in the fly. I didn’t know how strong the yugo ak’s are, extremely overbuilt. but it worked out none the less.

Now with the parts disassemble and the barrel that I just picked up that has the threads there are concentric enough to mount a suppressor. I’m just waiting now on the receiver to get here.

The barrel came in and it was a perfect fit. Also if you notice in the photo something attached to the end of the muzzle. I wonder what it could be for ?

MikeBlack47 · January 6, 2021, 5:25am

This was a quick mockup of it. I didn’t put on all the peice together. But its looking like its coming all together

MikeBlack47 · January 9, 2021, 11:29pm

well some good news the last major part is in. Recreator blanks came through for me. stress levels have dropped out greatly for me.

MikeBlack47 · January 16, 2021, 10:19pm

Well folks it finally made its way here. the receiver is as always made to perfection. The Yugo rifles are well know to be build like tanks but their parts are not always to spec. as you can see below the front trunnion shape is not prefect compared to the receiver. but its workable tho.

The rails are on point and the marking is correct and in the proper place. all the holes that are made on it are correct. also on a side this is a pretty thick receiver too. Got some weight to it. I expect nothing less from recreator and they delivered as promise.
