My Rust Blue experience: M70B1/AB2 FINISHED PIC 02.02

All Photos: Yugo M70 Rust Blue

I started out with this matching numbers kit, dirt cheap and I had the option of a fixed stock that was pictured with the kit or the separately pictured underfolder. I didn't bother to ask if it was a B1 or AB2 marked trunnion. The kit came to me and I saw the trunnion was marked B1; next thought: oh man, this is going to catch me some flak, who cares anyway.

Some background on the kit: It was naval jellied by one of the previous owners. Thats why it looks like that, bare and sad.

I decided I'd go with the rust blue process since I'm unemployed and I have lots of time. Thanks to VALMET_M76 at AK FILES http://www.akfiles.com/forums/showthread.php?t=31594
I am bluing the carrier just to see how much it would take, I'll probably end up polishing it back to the chrome finish later.

I bought some B1 wood for it

and a US made M70 grip from Ronin to help me with my 922(r) count

I will be showing my progress with the rust bluing in this thread.
I didn't blast the parts off, just went over everything I could with a brush.

Feel free to share your thoughts!

Here's the kit:

I let the parts sit for at least 24 hours, then boiled for at least 30 minutes.

The beginning. Round 1 - First Coat, First Boil, First Carding
(I left some original finish on some parts and rust blued over them - Trigger guard, top cover, gas tube, stock)

1 hr later



Top Cover was absent

[247Nino]

Round 2 - 2 coats, 2 boils and 2 cardings
Top Cover is in the mix!


The FSB AND RSB are not taking the bluing as well as the other parts

Gas tube went hiding

back to the box

Round 3 - 3 coats, 3 boils and 3 cardings
Brushed!

in different lighting

barrel looks bent, stupid compact camera

[247Nino]

Round 4 - 4 coats, 4 boils and 4 cardings
Black Oxide after boiling

Looks really light right?

On my hood, different light, looks really dark right? in person its more of a "gun metal"

Round 5 - 5 coats, 5 boils and 5 cardings


I put on a heavier coat of rust blue and let it rust about 40 hours...



Some parts are still uneven, instructions say they will blend with more coatings.



After 5 coats, 5 boils and 5 cardings I am going to stop bluing the carrier, it looks really dark but it isn't taking too well. Here it is with a coat of CLP. I will end up polishing this part later.

More pics after Round 5
Here's the M70B1 proofing, fugged that rivet up and really don't care, knew it wasn't going to come out perfect. IT IS CALLED CHARACTER! yeaaa!

You can see that the top cover is actually coming out really nice!

Round 6 - 6 coats, 6 boils and 6 cardings

Round 7 - 7 coats, 7 boils and 7 cardings








my tank

Round 8 - 8 coats, 8 boils and 8 cardings

My girlfriend read my thread and she said she liked what I was doing and it looked great so I asked her if she would help me out and I explained the Rust Blue Process and she helped me with round 8.
I guess I'm lucky because she was excited to help me.

Update on the parts:
The RSB and FSB are both getting darker, lights spots are evening out and everything looks to be one shade except the rivets. I think it might be from my super carding strength.
I washed the UF parts that I have not applied any bluing to and placed them next to my blued parts to compare the factory worn down bluing to what I have now. The rust blue is actually very close to the worn down parts. I thought the parts were actually a lot darker but it was all the oil and grease left on it from the time when it was a gun. I have added these parts in and I hope they will come out even closer to what I have done.

Round 9 - 9 coats, 9 boils and 9 cardings

They look pretty good even if they were added late... this is after one cycle:

[247Nino]

LAST CYCLE BEGINS!







That's how much rust blue was left after 10 cycles and spilling some. I soaked up whatever I spilled onto cotton balls and put those in a zip bag and ended up using them in the 2nd-4th cycles.
