Small cabinets with plastic drawers are easier to use if you mount them at eye level in your shop. That way items are easier to see without pulling out all of the drawers to get what you need.
If you have a small air compressor or other machine in your workshop that vibrates, you can dampen it by putting special foot pads of corrugated cardboard squares under each of the legs. Make the pads about 2 in. thick by gluing several squares together. Glue so the corrugation of one piece lies at right angles to that of the next square of cardboard.
When rounding out your workshop tools, consider adding two of the handiest tools used in shops of old-timers: a drawknife and a spokeshave. For the occasional job a drawknife can be used instead of the router for beveling work. It's fast and it can make fine cuts without any chatter marks. A spokeshave is like a plane with handles, making it easy to control the depth of cut for a perfect surface.
To store project plans, reference materials and magazine clippings, keep at least one two-drawer file cabinet in your workshop. You may be able to tuck them under existing workbenches. Or, if you will be building new workbenches, design them to accommodate the file-drawer cabinets.
Cords for small power tools like sanders and drills can get in the way when you work on a bench. One trick to keep them from interfering is to make up a chain of heavy rubber binders. Loop one end of the chain onto the cord about a foot behind the tool. Loop the other end over a cup hook screwed into the ceiling of your shop. When done, unhook from the cup hook and put the tool in storage.
If you are building a bench or table that won't be used for off-feed support for materials being processed, some general height recommendations include either 34-in. high, knuckle high, or hip-pocket high.
You want to do the right thing and include a first aid kit in your workshop. The question is, what should you keep in it? Here's a list of must haves: Regular and elastic bandages, antiseptic ointment, cotton swabs and balls, a tweezers, eye drops, elastic bandages with first-aid tape, gauze, a chemical cold pack, and a first aid information handbook. Also a list of emergency phone numbers either right near the phone or in the first-aid box cover itself.
Generally allow about 2-in. from the back of the tool to the wall, but be sure to leave space for any sawdust collection equipment you plan to install, including the ductwork and any attachments to it or to the tool.
Use caster sets to keep your major tools, even workbenches, portable. Wheeled tools and benches will allow you more flexibility, and will let you reposition for specific jobs like ripping long lumber or for taking advantage of natural daylight.
You can improve the visibility inside your workshop just by painting the walls and floors white. If your workshop is in the basement paint the sides of the window wells white too.
