The number of windows, as well as their sizing and placement, depends on your orientation, view, desire for ventilation, and needs for daylight and solar gain. Orienting more of your windows towards the south side of your shop and placing them high enough that they are shaded by the eaves in summer, but allow lower-angle winter light to come in, will increase your ability to get free light and heat from the sun. If your goal is to take advantage of passive solar opportunities, make sure that you carefully research the type of glass that is in your windows and look for something with a high solar heat gain coefficient. Higher windows generally allow for benches and tools beneath them, and relatively win­dowless north walls may be a place to arrange wood storage or mechanicals.
Timely article indeed. I’ve been playing with the shop layout tool on Grizzly’s website ( which helps you see how tools fit in a specific shop size. However, your insight and experience really helps with ergonomic considerations. When I first built my shop, the first thing I did was installing a wall mounted work bench – as my fore fathers had all done – Big Mistake! Soon-to-be project: ripping it out and building a mobile work bench on wheels (like the one you have pictured).
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.

There is significant evidence of advanced woodworking in ancient Egypt.[1] Woodworking is depicted in many extant ancient Egyptian drawings, and a considerable amount of ancient Egyptian furniture (such as stools, chairs, tables, beds, chests) has been preserved. Tombs represent a large collection of these artefacts and the inner coffins found in the tombs were also made of wood. The metal used by the Egyptians for woodworking tools was originally copper and eventually, after 2000 BC bronze as ironworking was unknown until much later.[2]

This simple jig makes laying out circles a breeze. Drill a 1/8-in. hole through every inch mark on a ruler or yard-stick. To draw a circle, place a pin through the number “1” into the center of your board. Add 1 in. to the radius of the circle you wish to draw, and insert a pencil into this number. Using the pin as a pivot, rotate the pencil to mark the circle. — Edwin Constantino. How to Cut Curves in Wood

First, let’s take a look at four placement options for the table saw, the machine that is at the heart of most woodshops. The first option (see the illustration) places it in the center of the shop, which lends maximum space and flexibility for ripping and panel sawing, as well as crosscutting long boards. The main requirement here is a shop that’s at least long and wide enough to allow room for the workpiece, both on the infeed and outfeed sides.
