Air Compressor Caddy

This project was completed during January, 2002. It was a shop project featured in ShopNotes, Issue Number 60 (November, 2001). When I saw this project on the cover of the magazine, it didn't take long to decide this project was on the "short list" of projects to make. I have the same Porter Cable compressor shown in the article so the measurements did not have to be adjusted to fit a different compressor. It is amazing how heavy a little "portable" compressor can be (almost 70 lbs)! But every time I wanted to use it I had to wrestle it around. Not any more!

Compressor Caddy with compressor The compressor caddy was constructed primarily from 3/4" birch plywood. A hole was cut in the back panel near the top resulting in a convenient handle. Finished dimensions are approximately 38"H x 25-1/2"W x 21"D.
Compressor Caddy with compressor and pneumatic tools A tool shelf is included in the design of the caddy so that frequently used pneumatic tools can be carried with the compressor instead of a separate tool case.
Compressor Caddy with pneumatic hose stored On the back of the caddy, a hose holder was formed from hardwood. Fifty feet of 3/8" hose is easily stored on the back of the caddy. One more thing not to have to tote along separately!
Compressor Caddy, front view without compressor or tools A solid steel axle runs between the sides of the caddy and supports the two 8" wheels. Additional hardwood axle supports were added to the inside of the caddy sides to help protect the sides from tear out.
Compressor Caddy, back view without hose Angle aluminium was installed on all the corners of the sides and bottom. The aluminium protects the wooden corners from being battered as the compressor is pulled over thresholds, steps and any number of obstacles. The aluminum also serves to add strength to these joints.
Compressor Caddy, bottom view A hardwood cleat was added to the front of the bottom so that the caddy would sit parallel to the surface on which it sits. In addition, a hole was added to allow condensation to drain from the tank without collecting on the wooden bottom.
Compressor Caddy, side view with tool storage shelf detached A side view of the caddy without the tool shelf reveals a slender profile. Without the tool shelf, the compressor may be lifted above the caddy and positioned on the bottom without working around the shelf.
Compressor Caddy, back view of tool storage shelf As a deviation from the original design, the tool shelf was not permanently attached to the caddy. Instead, two keyholes (shown in this picture) were formed in the back of the shelf so that the shelf may be easily attached simply by placing the slots over screw heads of screws in the back of the caddy. Then when the compressor is removed from the caddy, the shelf may be removed first leaving a clear access from above the compressor. This results in a much easier installation and removal of the compressor.
