In just a couple of steps, with just a few tools, you can turn just about any old block of wood into this fun durable toy.
Step 1: Materials and Tools
You'll need a block of wood, it should be roughly toy car size
You'll need four wheels, I used these casters from Home Depot because I liked the look of them, but any casters will do.
And you'll need two bolts with nuts for axles. The wheels you use will need to fit on the bolts and they need to be longer than your wood block is wide.
A big Fostner bit, the bit needs to be a bit bigger than the diameter of the wheels you're using. I used 2" diam wheels, so I used a 2.25" diam Forstner bit.
Two regular drill bits. The one should be just a bit bigger than the diameter of the bolt you're using and longer than your wood block is wide. The other should be a small diameter (about 1/8") and longer than your wood block is wide.
