The first is a transformation of the computer keyboard tray. You know, the kind that holds a computer keyboard on a sliding, articulated arm under the desktop. Using a knob beneath the keyboard, the arm drops the keyboard 6 to 8 inches and then it slides back, out of the way. This device is excellent as a support for a small table saw such as the Preac' The wide keyboard support is removed and a plywood base attached in its place. The saw is then screwed onto the base.

The result is a saw that is off your bench top, but immediately available. You reach under the bench, pull it out, lift it up and lock it in place. It can be swiveled and rotated into a convenient position for use. The top of the saw rests above the bench top so that there is no interference with work outfeed.

The second device is one of those articulated arms that holds a computer monitor above the desk top. Typically they clamp to the desktop and the monitor rests on a large plastic tray. With the one I have, the tray also rolls in and out on top of the articulated arm. This allows the monitor to swing out of the way when not in use.

As with the keyboard tray, these are fairly robust, being designed to hold a heavy monitor. The monitor arm could be used for a table saw if you have a larger one such as the Dremel. Some versions of these holders may be robust enough to hold a small mill or drill press. There are versions of these arms that attach to the wall also, which may be more convenient, depending on your shop situation. But what I use mine for, is as a holder for a Preac thickness sander. I removed the plastic tray and bolted the sander directly to the rolling platform. Besides the advantages of the clear workbench, it positions the sander up, closer to eye level and so that the work outfeed has somewhere to go. Attach some pluming for dust control and your sander becomes much more convenient to use.

The third useful old computer device is a printer isolation box. These aren't as easy to find anymore as the above devices. They were used to deaden the racket that early computer printers made. The one I found has an acrylic lid that hinges on the top and wraps down the front, has a muffin fan on the side to exhaust cooling air and is about 3 feet wide by about 2 feet high and deep. With the insulation removed. it makes an excellent spray booth for an airbrush. I added a switch to the front for the muffin fan, installed lighting and plumed it for air. The air comes in from a compressor in the garage via PVC pipe and terminates inside the spray booth with a moisture separator and a regulator.
