The pump is for a 10 gallon tank, 2" tubes, I used copy paper. I did hook up my airbrush compressor, and got movement in the paint. Seems as though it volcanoes on the side in 3 places (can see holes in the paint). I'm going to remove the paint off a couple old jig heads, and see how they turn out. Since the numbers (ounces) on the weights from 1 1/2 down. I decided to paint the 1 & 1 1/2 oz. that I use a lot so I can just pick them out. Oh the one's I showed were fully dipped, and I had to drill the holes out (egg sinkers), and the chipped. I'll file them down, so the line doesn't get damaged. going to half dip the others and splatter the top half with a brush. Again this was just a test before I buy a jig mold.
