Quad Power
The Quad XP-581 from Elenco provides four separate, fully regulated power supplies. Three are fixed and yield +5 VDC at 3 amps, -12 VDC at 1 amp, or +12 VDC at 1 amp. The fourth supply is variable, producing 2.5 to 20 volts of DC output at up to 2 amps. Line and output voltages are regulated to within 0.05 volts, and the supply is linear. All four supplies are shortproof as well. A current foldback circuit in each supply collapses the field in the event of a short, a current surge from the line, or an excessive current demand. Thus, both the Quad XP-580 and the equipment it's driving are normally protected from inadvertent errors or power company problems. Elenco built the supply as only Elenco will. The handsome, hooded metal case, - measuring 3-1/4" x 8-1/4" x 9-1/4" and weighing nine pounds - has a 3-wire grounded power cord for 115 VAC operation, panel meters for both current and voltage, and standard jacks for accessing the four regulated supplies. A two-year limited warranty and schematic is also included.

Lazy Scott Bearings
Never seemed fair to nail the "lazy" tag so permanently on the "Susans" but that probably has no "bearing" on the issue. Also called turntable bearings, they are the square, flat ball bearing devices YOU bolt between two flat objects to achieve rotation. Like that spinning center section of a Chinese restaurant table. We had these in surplus once and they were quite popular. To our chagrin, we discovered they could be bought commercially for the same price. So we did. The 4" version is rated for a 300lb. load, the 6" for 500lbs., and the 12" (round) for 1000lbs.

Pull, Pull, Pull Your Boat
A couple of pulleys just ready to be combined into the block and tackle you need for tiny jobs, like trimming your bonsai trees or hauling your model boat out of the pond. Get blocks with (1) or (2) sheaves and rig up whatever you need. Each block has an aluminum frame about 3–1/2” long with “S” hooks on each end. The sheaves, or wheels are about 2” dia x 1/4” wide, with a “V” groove that looks perfect to handle 1/8” or smaller Venetian blind cord. These dudes are perfect for demonstrating mechanical advantage in the physics lab!! But not for heavy lifting.

Blacklights!!!
Your choice of (3) different kinds of these wonderful lights that are all but invisible, but make whites “glow in the dark”!! Great for Halloween parties, dances, and stimulation of any phosphorescent materials. To avoid eye damage, please do not look directly at the filament of the light. The bulb types are a regular household shaped 60 watt bulb or a 75 watt spotlight shaped bulb. We also have a model which comes complete with a lighting fixture, reflector, and 18” blacklight fluorescent tube. This fluorescent model has a 18 watt bulb and 6 ft cord for a standard 120 vac wall outlet with a switch. Great goolish fun! (Please note: The "bulb" types do not glow as well as the flourescent types)

Disposable Scalpels
In the old days labs, schools and hospitals sterilized and reused things. Nowadays, as part of cost reduction efforts they throw them away. In keeping with this trend, it is no longer possible to get regular scalpels for modelers and home scientists to use for modeling and science projects. But we have gotten some good old fashioned scalpel type blades mounted in plastic handles. They are not sterile and not suitable for medical use. But with care, they are reusable in the home environment. And item for item they are cheaper than the old type, so you may be able to break even on the venture if you use them enough. We suggest that you stock up, however, so that you have a replacement handy if one breaks, the way you used to do with blades. 6" Long OA, they come with snap off blade shields.

Hemostatic Heaven
Hemostats are the clamplike devices dangling from veins and arteries in melodramatic operating scenes. Our particular collection are Pakistani surgical-grade instruments made of magnetic stainless steel. As such we rate them pretty good, but not fantastic. Hemostats look like little pliers. The jaws are relatively fine, with rounded tips. The inside faces are lightly serrated to get a grip on tubing or body plumbing. And the handles are much longer than the jaws. Now the heavenly part. Great hobby clamps that can be worked into small areas. Fine heat sinks for electronics. Good hook extractors for trout fisherpeople. Excellent tubing clamps for flow-sensitive chemistry experiments. Sizes are approximate length.

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=Ampere) (VDC= Volts DC) (VAC= Volts AC).

Large Rock Polishing Kit
Budding lapidarians will lap up this rock polishing kit which is so complete it even contains some rocks. The polishing tumbler has a (3) lb. ((1) qt.) fifteen sided rubber barrel and is driven by a 115 VAC motor. Overall dimensions are 6" x 6" x 7-1/2" high. In addition to the tumbler, the kit includes an assortment of jewelry findings and a detailed manual giving you easy to follow instructions. But don't think of it only as useful for jewelry making. As a hobby, our Uncle George for many years collected and polished a wide variety of rocks which he found interesting and made beautiful in and of themselves.
