Spray gun: Not every woodworking job gets a film finish, but most of mine do. And of those, everyone will meet a spray gun. For a million reasons, including making finishing fast and fun, I recommend using a spray gun whenever possible. It will raise your game and make you n0t hate finishing. (Click here to read my thoughts on purchasing a spray gun).
If your shop will be attached to your house or another structure, it will likely need to match its foundation, tying the two structures together so that one does not structurally stress the other if they shift differently. That may dictate a poured concrete or concrete block foundation. Regardless of your foundation type, a cold concrete floor will sap energy away from the rest of the structure if you are not careful, so think about how to insulate it well before you build.
In each case, we shuffled the bench, jointer, table saw, and band saw across to the top of the stairs, and then tied a rope around each to act as a safety while sliding the machines down the strapping on the stairs. Yeah, the table saw hit the wall, and the promise of a good mud and paint job saved my bacon. The rope worked well, and we were able to get everything down the stairs nice and slowly without any major issues.
I use binder clips for a lot of things around the shop, and here’s one that I thought I’d share. When I need to make multiple cuts all the same length, I just clamp my jumbo binder clip to my fence and use a 1/4-in.-thick wood scrap pinched in the clip as a stop. Works like a charm! When it’s not in use, I clamp it to the cord so it’s always nearby. — John Muchow
The standard option for a shop floor is a concrete slab. You’re probably not going to go to the trouble of creating a basement beneath your shop, although it is possible. The weight of most woodworking machines suggests that a concrete floor is the most solid and durable substrate available. It has the potential to be used as thermal mass to store heat from your heating system or from the sun, but it can be tiring and hard on your body to be standing on concrete all the time. You can add a vapour barrier, 2x4 sleepers and a wooden floor above the concrete to ease the tendency of the floor to strain your feet and back, or you can add anti-fatigue mats in key areas where you’ll be standing for longer periods.
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.
