Replying to Tips on pvc rail

Ive seen abunch of threads about cheap and easy rails and its obvious pvc is the cheapest. i just dont really know how to anchor the pvc to a base.  I already have a sturdy base made out of wood that with an older countertop secured with screws i counter-sinked with a drill bit. this didn't work out because it was just wood with a hard laminate but it makes for a great base for something. i just need to learn how to secure pvc to the top of it. thanks for any helpful answers on this
