How do I get rid of all this brown on the brass?

I'm thinking of a sanding wheel or a steel wire brush....borax maybe???
Hahahahahaha.... No don't worry... I'm leaving this one alone....

I'll post more soon but going to fettle this one with my dad as he wants to see how I do this. I'm leaving the platina exactly as I found it.

Primus no1 B stamped.

 

I would leave it “as-is” once you polish them I feel like they lost their soul.

 

@Pancho yeah this one is just staying like it is other than NRV, pump cup, tank gasket and burner gasket.... It looks like chocolate... Very nice patina

I bought a 1200 from a fellow collector over CCF and was in this shape when I got it. The collar was pushed down due to maybe a fall and was removed with ice. The finished patina was made by me

 

What a looker

 

@Pancho I had to put a leg back on, and desolder and put the pump tube back as it was broken off inside. Lost a few spots on patina....what did you use to force patina yours? Maybe I can put it back.

@Blackdog you would love this. I think I am going to just clean off what comes off with water and my hands and leave it. I actually really like the way it looks.

 

The tortoise shell look…very nice!

@Remus1956 hot lye bath. I have one of those SS pans used on chef stands and a coleman 413 bellow providing heat and submerged the lantern brass pieces until I got the right patina.

 

Throw it in a bucket of vinegar for a day and a half, it'll come out nice and red, none of that nasty brown.

@Rangie I thought it would look better in pink haha..

 

@Pancho I need a way to just do a spot or two...hmmm gonna google it

 

@Remus1956
Sent you a PM

 

For that certain ehhh… “aesthetic”: copper spray paint. Some would-be decorator was out of chalky farmhouse whitewash that day.

 

@Pancho @Pharael @Gurgle @Blackdog
This is the small area I was thinking to fix
The stove arrived with a leg popped off and had to take the pump out and return it.
I think I'll leave it unless there's a way to just treat spots....

Yeah I know it's not the correct trivet but it is what came with it

 

Consider applying ‘Liver of Sulphur’ on some scrap brass and through practice, see if you get the finish you are after.
Reasonable price on Amazon.

@Remus1956 No idea of the circumstances here so you might have had good reason, but I've always managed to pop pump tubes out and back in without cleaning the brass (and usually without having to add any solder). As both surfaces are already tinned they just seal back together fine.

 

@Blackdog yep .. cleaning the tube was a last resort. I kept getting weeping kerosene when I just filled the stove. It actually leaked there when I got it .. That and the ovalized hole where the pump shaft goes into the cap kind of leads me to the point where it was pumped really hard just likely to try to keep it running.
The NRV was also sheered off and my tool would just spin. I suspect that it was run into the ground.
I couldn't get any interference fit that wouldn't leak after I fixed the NRV issue so I tried to reflow the solder that was there but it would not take. I must have tried about 2-3 times and decided to clean the tube end and re-tin it with solder. It took immediately. I think whomever had this stove used it until they just couldn't get it working anymore and let it go. When I did finally get to the NRV it was made of cork.

There wasn't even a gasket for the burner... It had remnants but was mainly a brass to brass seal.

After running it is lost pressure so reflowed existing solder where the air pressure screw was... That took the first time.
On this one I tried pretty hard... Just couldn't get it to reflow or even add solder to keep the tube there sealed. I was nervous to keep heating it up and possibly damage it.

 

@Remus1956

Well done.
