With an orbital sander and good sandpaper you can smooth wood evenly and easily with first-class results. When flush-sanding solid edge-banding, draw a squiggly line across the joint before sanding. The edge-banding will be slightly proud of the plywood veneer, so the pencil marks provide a visual aid to make sure that you’re sanding flat, and that you don’t sand through the plywood’s veneer. As you go, you can also test for a smooth, level transition by gently scraping your fingernails against the transition. If it’s smooth, your fingers will not catch on the seam between the two pieces
Personally, I think it sucks to have to lug massive pieces of rough lumber and 4′ x 8′ plywood sheets all the way across a shop. Much respect to basement dwellers who have little choice in the matter. But for those with garage shops, you should think about storing your sheetgoods and solid stock near an entrance. This way when you come home from the lumber dealer, you can back up your vehicle and quickly load the stock into the shop.
Radial-arm saws, sliding compound miter saws, and powered miter boxes (chop boxes) used for crosscutting long boards are best located against the longest wall of the shop, as shown in the first option in the illustration. If the saw is to become a stationary machine, it’s typical to mount or build it into a long, narrow support table fitted with a fence.
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.
Let’s be clear about one thing: No workshop is perfect for everyone. If there were, I could simply give you a precise plan to follow with clear dimensions. Every person who comes to the hobby, avocation, or profession of woodworking has his own particular collection of tools and his own peculiar work style, skills, and desires for the kind of woodworking he wants to do that gives him a unique approach as to how he will lay out a shop: where the tools should go, where lumber and supplies are stored, and how much bench area he needs.
