I read somewhere that you can chemically change your brass tubes to black "instantly & permanantly" by dipping it in " ? " something.

I want to make my tubes black (without painting) The paint I use bubbles and comes off with CA, and I was looking for another route to take.

Anyone want to venture a guess? Googled it, but couldn't find anything

TIA,

Tim

I know liver of sulpher will turn copper black, but I'm not sure how well it works on brass. You can get it at a bead store. Also check at a stained glass supply house, they have bottles of patina that may work on brass.

Check out Jax Chemical Company.

They have patinas for brass, copper and all kinds of metals, and they work great. Black, brown, etc.

But beware, the green doesn't really work. Maybe on copper, but not on brass.
 
YOu might also look at WWW.XLGEL.NET they have a gel liver of sulfer I have a 2 oz bottle. It can be brushed on ful strength or diluted in hot water.

Check out your nearest stain glass shop. They have the chemicals to patina lead, brass, copper.
 
I have been thinking about how to solve that problem, so the last time I was in Lowes I looked at paint options. I initially was thinking of getting some model enamel at a hobby store, because I use it to paint the bodies of the RC cars I build, but I'm at Lowes more often so I had a look.
I picked up a can of Rustoleum Automotive enamel in gloss black and a can in gloss white. I painted a couple of tubes and let them dry over night. I lightly sanded the tubes, and applied the CA - no bubbles, no nothing. worked like a charm.
 
why not paint the inside of the blank instead, then you reduce the chance of seeing any glue lines
Drill the blank to one size below what you need, and sand it up to fit.
Try using Rustoleum Fusion, as it is for plastics
 
I have the same dilemma. The problem is I am doing clear casting so it has to be a nice smooth glossy black. The problem with the solutions such as black-N-it. Is they don't give you a smooth glossy black they give a flat patina that is fine if you are doing a snake skin or something like that but not for clear casting. The best paint I found so far is Testers spray paint. Testers hold up to CA and does not melt all the others from the home stores that I tried don't hold up to CA neither does a marker. The best bet would be powder coating but that takes quite a bit of equipment to do.

I would like to hear some good easy stuff on a smooth high gloss black that can stand up to CA and then get casted in PR.

thanks

What if you marker the tube, then give it a CA finish?

Hmmm and then CA glue parts or pieces to the CA coated tube. Something to try did you try it or is a thought.

Just had another thought to try. Paint the tube as usual with spray paint one of the problems with spray paint is it scratches easy when gluing parts on. Now take that that painted tube and put a CA finish on it. I would put it on the lathe and give it a spin and apply a thin medium coat of CA. That would stop the scratching and you should be able to glue parts to it with CA.

Thanks for the tip. This is how we figure things out. This all theory just got to try it to be sure it works. That is where time and money comes in to play.

thanks
 
It was just an idea.

I've done a few clear resins that I painted the hole and they have always come out great.
