Cutting Melamine Coated Particle Board
I'm making a small shelf out of that melamine-coated particle board that the home centers sell. It's going to need to be cut to fit on a bathroom wall with some angles and a cutout for a metal grab bar. It's roughly 36' long, with a depth that varies from about 24', tapering off to only 3 1/2' at the other end. Only the top will be visible, so I only need the top to be chip-free. There's a rough sketch of the shelf at the link below.
I'm concerned about chipping the melamine when I cut it, but since this is a one-off project, I'd rather not invest in an expensive saw blade for my table saw. I have a decent blade in there now (I forget the pitch, but it's one made for 'trim', so it's finer than the standard rip blade that comes with most saws). I also have a router, circular saw, and a jog saw available. Any suggestions for making the cuts with a minimum of chipping?
