finished halfpipe
the finished ramp with a coat of splotchy polyurethane. We contact-cemented the masonite to the ply so we wouldn't have to use screws on the skating surface. (we still used some in spots) And, incidentally, if you're building a ramp, don't use drywall screws (the ubiquitous black ones) to attach your riding surface. Note that drywall screws have a "bugle head" -designed to keep the screw from penetrating too far into drywall. Well, that same feature keeps the screws from being driven flush with the surface of any wood -so you got a bunch of screw heads sticking up, anxious to remove any skin that might be happening by. Get some real deck screws (the best ones have a tapered head with self-countersinking nibs), or countersink the screws -it'll make all the difference.
