The drawers are very simple to make. First, cut the drawer bottoms from ½" plywood. Make them about 1/16" narrower than the distance between the dadoes and full length. Cut strips of solid wood or plywood equal to the inside depth of the drawers you want and cross-cut them to length. I assemble the drawers with glue and nails. Note that to store a 5" tall object, you don’t need a 5"-deep drawer – you just need 5" of headroom.
We cut the supports 16 in. long, but you can place the second shelf at whatever height you like. Screw the end supports to the walls at each end. Use drywall anchors if you can’t hit a stud. Then mark the position of the middle supports onto the top and bottom shelves with a square and drill 5/32-in. clearance holes through the shelves. Drive 1-5/8-in. screws through the shelf into the supports. You can apply this same concept to garage storage. See how to build double-decker garage storage shelves here.
The final corner of my shop houses my Grizzly G0703P mobile dust collector. I upgraded to this unit shortly after setting up this shop as my last dust collector was setup to exhaust air outside. The separator I made for it wasn’t efficient enough to modify again for a canister filter for exhausting air inside the shop. I really didn’t want to deal with modifying my dust collector again so I got this. Above the dust collector is my retractable air hose reel that I mentioned earlier. I like having this here as the only times I use compressed air is to fill up the my vehicle tires or to spray a finish which I do outside.
You can also use Google image search to research a project. Unlike the PDF search, the image search provides a photo of what the project will look like, which is helpful in determining if you want to pursue building it. By doing an image search for how to build a step stool, you will have a ton of options that all lead to woodworking plans of various quality. (The how to part of these is important—otherwise you’ll just get pictures of step stools.)
