Slide Pot
Nice little slide pot of the sort used for e.g. speaker volume control. Which is to say it is low wattage, probably under a half, but we don't know for sure. It has a 3/8" x 1-3/8" x 1/4" body with a 1/2" long constant resistance between the inside contacts, short between the outside, and 0-200 ohms variable between any inside and any outside contact. Circuit board mount. CTS SA 1315 8914.

Photometer Box
Bunsen-Dibdin photometer box for mounting on a meter stick. Normally used in a physics lab together with light sources that also mount on the stick, you could rig up your own lights and have a complete lab experiment set. Cenco #86445, it is often sold as a replacement item. No instructions.

Rubber Stopper
Pat's been hanging around the medical supply house again. We now have a boatload of rubber stoppers, the kind you see on bottles of liquid medicine, crimped down with an aluminum collar. (Pat didn’t buy the aluminum collars.) The medicine is removed via a hypodermic needle through the stopper. The rubber stoppers come in blue, gray or orange. All three stoppers fit (13 mm) dia opening. The blue and gray are 3/4” across the top, 5/16” top to bottom. The orange are 9/16" across the top and 9/16" top to bottom. Why would you want them? Because they'll fit many of the small wide-mouth and slope-shouldered bottles in our Bottlemania listing. Pat's really good!

Pull, Pull, Pull Your Boat
A nice pulley 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 this block with (1) sheave 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.

Timing Motors
These are really geared reduction motors, but much smaller and of lower power. Often used to operate cams and switches in electrical circuits, or to drive displays, they can generally be operated in continuous applications if not heavily loaded. Most are about 2" dia. x 1-1/2" thick. Remember CW means “Clockwise” and CCW “Counter–clockwise,” looking at the shaft.

Miniature Screwbases

Shrink Plastic
Incredible stuff!! And even better than those dinky cutouts you used to make! Our each is a pack of (8) 8" x 10-1/2" shrinking plastic sheets that start clear and stay clear. Draw a design, write a message, create a sign, whatever. Cut it out, bake it in a 350° oven for about 3 minutes, and it shrinks to 45% of its original size. Problem with certain pencils and markers on the slick sheets? Try a light sanding (320-400 grit) before writing on it. (The surface will be more opaque.) What a fun way to make small errors become insignificant!

60 At 60°
This black-plastic helical gear leans toward the unusual. It is 2" dia x 3/16" thick, with its (60) teeth set at about a 60° angle. A 1/4" dia steel shaft extends 9/16" on one side. On the second side, the side with the 1/4" x 7/16" dia bushing, the shaft extends an additional 1-3/16". Definitely a new slant on gears.

Learn A Trade
Learn geometry, or learn to build the world’s coolest sand castles. Our each is a set of (4) geometric shapes in brightly colored transparent plastic. The set of (4) includes a 3–7/8” cube, a 3–7/8” x 3–7/8” x 1–15/16” rectangular box, a 3-7/8" dia x 3-7/8" cone and a pyramid with a 3–7/8” sq base. All shapes are open on the bottom, the better to get the sand into them. And out of them.

Safely Caged
Cage the wild light bulb in order to protect it from its natural enemy, Vandalus urbanosa. Unlike the domestic indoor bulb which can be protected with a silk or paper shade, this more-endangered bulb is found outdoors or in rugged industrial habitats. Our yellow-plastic cage is available for bulbs of 100 watts or less. (Bulb should not touch plastic.) This cage is 6–1/2” long x 5” dia at its widest point. One side has a release latch for access to the bulb. They fit over a medium-base socket to protect the lamp in it. Hardware included.

Hello, My Name Is…
Ima Bargain. And I come in a very mixed bag of plastic badges. Most of us are rectangular, some round, most off-white, some black, most with pins, some with pocket clips, and all of us have been sitting around a long time, waiting to be used, so you'll get a broad assortment. Sizes range from 1/2" x 2-3/4", to 2-1/2" round, to 2" x 3-1/4"-you know, badge-sized. Most of us have little grooves to take a Dymo® label tape, 3/8" or 1/2", but we're all ready for a marker or sticky paper label. The best news is that paper labels won't fall off us the way they do from every suit fabric known to humankind.
