My dedicated shop space is about 8′ x 4′, the rest is a one car garage that needs to stay open for my wife’s car. I will sometimes set up some plywood and sawhorses in that space for assembly though. The section that is my dedicated shop has a floor made of 2″x6″ lumber stretched out over joists on top of dirt. It is an old floor filled with knot holes, cracked or broken boards (with temporary plywood screwed over them) and just generally uneven. If I cannot build a shed as my new workshop I will be looking at redoing the floor in my current space. Not sure how I would go about it though.
The shop you see in the layout is my current setup and has evolved over many years to accommodate most importantly the acquisition of newer equipment but also better work flow. It is a free standing two story traditional barn style with office and storage space on the second level. Lumber and supplies are moved in and out of the shop through the front overhead door. To the left of the door are the lumber and plywood storage racks. Across from the lumber rack and to the right of the overhead door is the radial arm saw, miter saw and mortise utilizing a single fence system for all operations. Below and above these are cabinets and storage for misc. power hand tools.
The table saw is always connected to my dust collector with a couple pieces of 4” flex hose and some 4” sewer and drain PVC pipe and a homemade blast gate. The port on the table saw is at the rear of the cabinet and this particular area of the shop sees the least amount of foot traffic so I have no problem just leaving the ducting on the floor. I also always have a few other cords on the floor here. I see this as the same principle as walking onto a porch. You know the steps are there so you pick up your feet. I know the pipe is there so I pick up my feet. Not a trip hazard in my opinion.
Woodworkers are a social bunch, and there are a few popular forums where people share thoughts on tools, discuss technique at length, and—of course—upload their plans. Some of the most active online woodworking communities include Lumberjocks, Woodworking Talk, Wood Magazine, WoodNet, Kreg, and Sawmill Creek. Search those to see if they have what you’re looking for (either with their built-in search tool or with Google’s site-specific search, e.g. site:lumberjocks.com side table).
