Just a word of caution for those of you homebrewing...

At school, we have community protective equipment (masks, gloves, etc.) and the careless students contaminate the gear to the point that you can't avoid it and the salts are going to burn you sooner or later. Even if your gear is clean, you may be splashed and burned...

We are prepared for this with strategically placed squirt bottles of vinegar. Vinegar neutralizes the salts very rapidly and prevents further burning. If you are going to do your own bluing, I highly recommend having the squirt bottles near. The large triggers are easy to operate while wearing gloves, and are a lot easier than locating vinegar in the kitchen, opening a screw top bottle and pouring.

While water may wash off bluing salts, it doesnt neutralize the burn. And $5 in prevention beats hundreds in medical bills.

I guess BigAl did not get to try out the Roebic lye for bluing this weekend.

Nope, I ended up parkerizing a few instead. It's on my list of next to do. Pupwags looked very nice...

need to get me some vinegar!

So Bigal, the Roebic lye worked well? How long did it take you to mix the chemicals? I look forward to your pictures, did it come out black or blue like pugwag's images?

Yeah BigAl, did you use the Lye method? I'm getting confused since there are a few methods posted in this thread.

We mixed up 8lbs of Lye 4lbs of Nitrate and 1 3/5 gal of distilled H2O. Heated it on a propane burner outside, after it started boiling, we added the parts and let them cook for 30 min.s. Piece of cake!!!

The finish is almost black, but matches the Yugo barrel and parts PERFECTLY. Where's the pics BigAl???

555th

Were you following BlindHogg's instructions? He lists 5 lbs of lye to the 2.5 lbs of Soda Nitrate. It sounds like the ingrediant percentages are very flexible.

I did the math and increased it till it would cover the parts in the kettle. :wink:

not the greatest pics. the handguards are from ironwood, the original was damaged. the engraving was by mario at POHF, he does the best work I have seen.

There is still some cosmo around the rivets and nooks/crannies I need to clean up, plus it really soaked up the oil and could use some more..

BigAl

Did you do the top cover as well or just the receiver? Was that bead blasted prior to blueing? It looks really good. I can not wait.

Top cover is original finish. it was bead blasted. i did the receiver/trigger guard/trunnion/rear block. The pictures do not do it justice. the finish matches perfect, it is just holding oil in some places. the kits look highly polished when you get them, but clean off all the oil and cosmo and they are a matte finish.

The matching of the top cover to the receiver is rather amazing given they were done by different processes and times. Looking at the picture you can not see any difference in the top cover overlap and the receiver.

I was planning on using aluminum oxide beads to blast and then blue. Now to just get some tanks/pans.

Thanks for the pics and info.

my blast media is a mixture, mostly aluminum oxide but it does have some black beauty and some super fine stuff in it also..

the finish is an exact match. i'll try to finish cleaning/oiling up and post some better pics. i think I'll do my Tabuk sniper this week if I can get 555th to cooperate..
