guitar pickups?

Styrene can be bought in many thicknesses and many colors. Sheets can be laminated together, the cheapest way is with lacquer thinner. Liquid model cement or even tube glue can also be used. Cut with a razor saw or hobby knife. Sand with successively finer sand paper (I use up to 2000 grit, it is available from auto parts stores, used for polishing before final coat of paint on a car body). I have always used enamel paints, but you can also use acrylics. Be careful with lacquers as they can craze the styrene. Check out any on-line hobby shop for all the material you need.

Ok, thanks!  I'll be airbrushing it, so, what paint is better for that?

I would use enamels and then give it a coat of Testors Glosscoat in the spray can.

Check out Stewart MacDonald (www.stewmac.com) for everything to make pickups.

Didn't say what kind of pickup you were constructing - P-Bass, J-Bass, Other.

They have basically every part you would need to build any kind of pickup

Exactly what I was going to say! Here's the direct link to it. They've been offering these kits for the last four years now. You can also get wet-sanding papers from them up to 3600 grit smoothness.

This is where I buy all my stuff for finishing guitars. This is where I bought my buffing wheel.
