Self-Adhesive Donut

Self-Adhesive Donut

A two-layer foam ring with a sticky side, 4-3/4" OD, 1-1/4" ID, 3-3/16" thick. If the stickum is the bottom, the middle layer is dense black foam and the top is squooshy yellowish foam. Originally part of a hose attachment system, these things might make good bumpers to protect your head and the brick wall from damaging each other when it's pounding time.

Thermal Sensor

Thermal Sensor

Heat switch that is normally open below 135° F and closes at higher temperature. Imagination is the limit here. We don't have formal electrical ratings but believe it can handle about 2 Amps @ 120 VAC. It can be used (perhaps with a relay) to trigger a fire alarm when mounted near a furnace, in a garage, or in an attic. How about using it to shut off electronics or motors when overheating occurs? Or to activate a fan for cooling? Use it to record how long the furnace is on to rate its efficiency. 5/8" dia x 3/8" sensor head with (2) 1/4" x 1-5/8" long fixed leads.

Make Molds For Free!

Just leave bread in a damp place. Or buy this stuff and make casts of solid objects, anything from faces and fingers to celery and crucifixes, with quick-setting Instamold. (We'll sell you 10 oz. of the Instamold compound, but you provide the water to mix it with.) Then fill the molds you've made with plaster, wax, or Permastone-yes, we sell Permastone too. It's an extremely strong casting medium with a clean white hue when set, waterproof and scratch resistant. Each can we sell has 1-3/4 lbs. of Permastone, to be mixed with water.

Mini Mandrel

Steel mandrel, 1/8" dia x 1-3/4" long. It has a slot head screw fastener with a fiber washer and can handle cutoffs etc with as little as a 1/16" bore and as much as 1/4" thickness. Good for the cutoff wheels you will find listed nearby and similar items for your rotary tool. PLEASE NOTE: In our catalog the size is listed as 3/32". This is a misprint. The correct size is 1/8" shank. Sorry.

Chuck Buddy

Every 3/8" power drill's best friend. It has a black plastic cone that will fit over a standard chuck with the drill bit for a pilot hole still chucked in place. On the end of the cone is a steel tube with a tip to hold a standard 1/4" screwdriver bit. Leave the driver in the buddy and slip it on and off the chuck to change quickly and easily between drilling pilot holes and driving wood screws. That's what friends are for.

A Real Grabber

Okay, it isn't the cheapest magnet in the warehouse - but we dragged John's 165 lb filing cabinet around the dock with this 4-7/8" x 1" x 3/4" ceramic magnet, we're rating it conservatively at 100 lbs of pull, and we think it's a bargain. It has a 6" bracket with mounting holes on 5-1/2" centers, plus a 1/2" ID eyehook bolted into the center of it. It's all set to troll the bottom of the lake next time your filing cabinet falls overboard.

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!

Wonder Magnet

Absolutely magnificent magnet!! Very strong - we estimate it has a 35 lb. pull - neodymium-iron-boron (rare earth) that is only about 3/4” x 1-1/8” x 7/16” thick. It is actually trapezoidal, so the 1-1/8” dimension slants from 1” to 1-1/4”. They are pretty clean take-outs, painted silver, white or black, and may have some very small chips. Be careful!! These guys will murder a computer or audio/video tape. A pair will leap into a deadly embrace from over 6” apart and may knock chips off themselves from the force of their impact!! A single magnet holds (4) of our catalogs (11 oz, 5/16” thick) to the side of a steel file cabinet. We cannot say too much in favor of this magnet!!

Painter's Pals

Cheap enough to buy a bunch and toss 'em away after small jobs-or equip a bunch of helpers. The 6-piece painter's set includes a 9" dia drip dish with clips to hold quart or gallon cans; a vented 11-1/2" long stir stick and small brush, both of which clip to the side of paint cans; a scraper with a snap-open cover and a removable blade; plus two foam brushes, 1" and 2". All in easy-to-find bright orange plastic, and the drip dish doubles nicely as a flying disc toy during coffee breaks.
