There are a few things particleboard is NOT. It’s not medium density fiberboard (MDF)—a material with greater density and weight composed of more uniform particles. It’s NOT oriented strand board (OSB), a material composed of large wood chips and strands that’s structurally equivalent to plywood. It does NOT have great nail or screw holding ability, nor is it all that water resistant; water can quickly cause the material to swell and lose structural integrity. But if you need something flat and cheap for use in a dry place, particleboard will do you proud. Learn how to make a plastic laminate tabletop with a particleboard substrate.
Not long ago, I needed to make some angled wood parts to build a new soffit on my garage. I didn’t have the customary tool for the job, but I had some steel joining plates. I screwed through one of the holes in the plate, set my angle, then added another screw to lock the angle. I could then use it as a template to mark all the pieces at the same angle and cut them with my circular saw. — Ryan Bartsch
