I started on the roll-around shop cart by building the base. It's basically just a big box made up of two frame and panel assemblies joined by a shelf and bottom panel.

Material - Since I expected the cart to see heavy-duty use around the shop, I decided to use construction-grade ("two-by") lumber for the frame pieces. (I used Douglas fir.) Construction lumber has a few things going for it. First, ifs beefy and heavy — a perfect choice for a shop cart. And it's fairly inexpensive.

But construction lumber does have a couple drawbacks — which are easy to overcome. For one, you'll have to spend a little time picking through the stack of lumber. I like to separate out the lumber with the straightest grain, fewest knots, and minimal defects. Then I select lumber wider than what I need. This way, I can trim off the rounded edges to square it up and cut around any remaining knots or defects.

One last thing. Construction lumber often has a high moisture content (the lumber I picked out was sitting outside).

So once you get it back to your shop, it's a good idea to sticker it and let it dry out before you start cutting any workpieces to size. Note: Stickering is a just a fancy word for propping the lumber up off the floor and separating the pieces with a few

strips of scrap lumber so air can circulate around it. After the stock has 1 had a chance to dry out for a few weeks, you're ready to start cutting. ^^

Side Assemblies - Once the stock is ready, you can reference Figure 1 for the dimensions needed to build the side assemblies for the base. Each side assembly starts out
