Powder Coating Boolits

Your getting awful close Jim . . .

Those look like you used a static gun!

Great... now I'm gonna go all OCD on coating more boolits today. I have yet to achieve perfect, static gun-like results like you have. Close, but not perfect like those. But then again, I'm not standing them up... they're all just piled up in an air fry basket.

Did you use poly pellets on that batch?

@phlier Thank you for the response.... I will give that method/process a try when I tumble my next batch. Also, good tip on the heat. I will use lowest setting next time as well.

Anytime.

The only real difference between my method and what most guys are doing is the fact that I use Phosphoric acid. IMO, phosphoric acid passivates the brass better, making them more resistant to tarnishing. It also puts a level of shine on them that I was never able to achieve with citric acid.

When you're working up your dose of phosphoric acid, if your brass starts to come out with a pink-ish tinge to it, you need to back off a bit. I use the most I can that doesn't result in pink brass. One thing about that pink tinged brass, though, is that it's so thoroughly passivated, it is much more resistant to tarnishing. But the pink color comes from removing zinc from the outer layer of the brass, and zinc is a good thing in brass... you really don't want to remove too much of it. But even really pink brass isn't damaged, as it's just the very top level of the brass that has had too much zinc removed.

Might want to start out at 1 teaspoon per FART load, then go up by 1 tsp until you get pinkish brass. Back off 1/2 tsp from there, and you should be set. IMO, you shouldn't go by how the brass looks; it'll probably look fantastic with just 1 tsp. You want to use the max amount of acid you can (without getting pink tinge) in order to more thoroughly passivate the brass.

There are some really good articles out there on passivating (making metals more resistant to oxidation) brass. Might want to do a Google search and read up on it if you're interested in producing brass that is resistant to tarnishing.

I used reject boolits to do powder testing.









Do small batches/amounts of powder at a time, the more you tumble them the more the PC blends together making a less appealing finish

Beautiful boolits!!

I like the gold very much. Was that one coat? Do they sell in less than 1 lb batches?

[oldsman]

the gold was two coats with the shake method , no bbs
the others was done with lyman tumbler with the small bowl with clear cover , one coat , no bbs
next time I am going to try the gold in the tumbler to see if it will cover in one coat
I like the tumbler method I can see the coverage through the clear cover
they do sell their powders in 8 oz I think they come in a bottle as 1 lb is in a bag,
go to their website and you can see for yourself,
I bought some of the 8 oz empty bottles and they come with screw top lids and 1 lb of powder will fit

Yes I did...I am converting all my PC shake tubs to the poly beads.

It's interesting how some colors form "snowflakes" and others actually mix. I like the green- red and green- brown colors. Do you think this stuff would mix with Cardinal Silver as well?

[Conditor22]

Too many colors, too little time (energy)

[cwlongshot]

My own mix of colors to make this Green.
