update ...
The acrylic dyes I am using cause the CA to get really stringy and weak ... the resulting bond easily peels off of a brass tube with a fingernail. It's got no hold at all ... either that or the acetone is doing it...
I'm gonna mix some pearl-ex color powder to some CA and see what results I get ...
Side note ... pretty hot exothermic reaction from the mix of CA, acetone, and a few drops of acrylic dye ... I was concerned that the little 1 oz bottles might actually MELT from the heat. These bottles handle the acetone just fine, but they don't seal particularly well ...
If I find a mix that actually works that I can keep around in small quantity, I plan to store perhaps a half ounce of it in one of my tiny CA bottles ... the only colors I am concerned with at the moment are blue and black. Anything else tends to go fairly nicely with polished brass (gold).
Seems like I'm going to need quite a bit of powdered pigment to make a difference in coloring the CA still in the bottle ... it's coming out quite clear, with little specks of color clumps. I may need to find some alcohol based inks ... I know oil based is a worthless idea, as oils will make the CA cure way too fast and not bond properly.
In any case, I didn't add any acetone to the current batch with just Pearl-Ex powder in the CA bottle ... let's see if that affects the bond strength.
