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.
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).
