Adapting to AC-Surplus Transformations
There is an entire class of transformers that surplus dealers call "AC Adapters." What we really mean is transformers that plug directly into the wall (primary voltage 110 VAC), and via a cord and/or plug provide various levels of output current at variou s voltages. It is a rare buyer of surplus that gets the plug configuration he/she wants, and many get snipped off (plugs that is). They are handy power supplies, battery charging units, substitutes for batteries in toys and games, or for providing safe il lumination to models and displays. Be sure to note whether the output is AC or DC (Direct Current, like a battery) and whether it can provide enough current for your application. Unless otherwise noted, all are suitable for indoor use only. Stick with us and you'll get the hang of adapting to AC...and at much lower prices than your friendly appliance/game/computer/calculator shop asks. Unless otherwise noted, all adapters are for 115 volt AC primaries, and all have about 6 ft. cords. (MA=Milliamp) (A=Amphere) (VDC= Volts DC) (VAC= Volts AC)t

Fiber Optic Cable
If far-flung fiber optics are in your future, consider our 30-ft section of F/O data transmission cable. Each side of the blue-jacketed (or maybe green-jacketed) dual cable is 3/16" wide, insulated, and holds approx (20) very fine fiber optic strands. Not good for light transmission. Labeled OFNP.

Duck-billed Locking Pliers
Welders and other people with marketable skills know that these are sheet metal clamps, but the rest of us treasure the sundry other wonders they perform. (Wasn't that poetically put?) The handles lock, and the 3" wide jaws are just ducky at straightening out bent stuff, taking cookie sheets out of hot ovens, clamping oddly-shaped things with even pressure while the glue dries, snapping tile or glass after scoring it, and thumbscrew tightening. Made for Michigan Industrial Tools of drop-forged chromed steel, 8" long.

Soldering Gun in a Jar
Wire glue-the solution when you can't find the soldering iron, don't want to bother, are out in the woods, don't quite trust a fifth-grader with a hot gun, can't reach the connection with both hands, whatever. This stuff conducts low voltage AC and DC circuits in a permanent bond and is easy to use. Our high-tech support group suggests that a toothpick is a good way to apply it. Cures overnight. Our each is a 0.3 oz/9ml jar.

21st Century Walking Stick
Walking sticks have moved into the space age! This walker's/hiker's friend has futuristic features and the look of an inter-galactic weapon. The high-quality collapsible aluminum stick extends from a packable 27" to a full 56", and has a carbide tip with a rubber cover, a removable 2" dia disk to keep the stick from sinking into soft ground, and an internal shock absorber that can be turned on or off. At the top, a 5-LED flashlight with a 90° pivot is embedded in a molded-plastic cane-style handle to light your way. For mountain trekking, lengthen the stick, slip the adjustable canvas wrist strap over your hand, and clutch the stick by the padded foam section below the cane handle. Directions, diagrams, and 1100mm to 1350mm gradations are marked clearly on the 3-draw pole. We'll pick a black or anodized red, green, blue, silver or purple version for you.
