how can i make my own humbucker cover for my epiphone les paul special II?

I have seen covers formed or carved from wood, plastic, bent from metal, just remember to leave room for the adjustable pole screws if you have them and the thicker the top, the less sound goes through. This is a rather simplified answer, however many rockers took off the covers to get more and better sound out of humbuckers, so you are maybe regressing---but good luck and more info would be available at http://www.mimf.com
