Spring Scales
Not to worry! These scales can be used in any season, not just spring! Made in Canada, these plastic and metal spring scales are calibrated in grams and Newtons. (Wasn't he the guy who invented fig cookies?) Also known as force meters. Smaller ranges are more sensitive, but have less capacity.

Pulley Sheave Wheels
Also known as our "red pulleys". These are the plastic pulley sheaves ONLY, no axle, no supporting frame (i.e. "round wheels"). All have a deep "V" groove around the circumference and 4 mm centre hole. These make excellent wheels for model vehicles, also necessary as "drive pulleys" for belt-driven electrical models.

Gears
The basic unit of how we sell gears is the "stem" or "sprue", similar to how you find moulded plastic model parts connected when you first open the box. Each stem holds 4 gears, one each of:
40 mm dia. / 40 teeth, 5 mm hole
30 mm dia. / 30 teeth, 5 mm hole
20 mm dia. / 20 teeth, 5 mm hole
13 mm dia. / 12 teeth, 1.5 mm hole
plus 3 shaft adapters, all moulded out of the same tough plastic (available in blue, green or red). The three larger gears are bevelled, so they can be used in pairs to transfer rotational power 90 degrees. Shaft adapters are "plugs" used to adapt the 5 mm (3 / 16 inch) diameter centre gear hole to a 3 mm size, if necessary. Note that the smallest gear has a centre hole that matches the shaft diameter of our electric motors ELEC.13 and ELEC.45 and makes an excellent drive gear. Made in Canada.
GEAR.05     Whole stem (4 different gears + 3 plugs)      $2.00/stem
GEAR.06     Package of 4 stems (16 gears + 12 plugs)    $7.50/pkg

Gear Kit
Contains gears as above (6 whole stems), cams as below (4 different shapes), Jax Joiners, bamboo skewers, "Meshing Around With Gears" booklet, and 8 X 11 inch sheet of corroplast to make 4 different working models (gearing concept model, trundle wheel, fan and winch) illustrating gear principles: gear meshing, gearing up and gearing down, and compound gearing. A great introduction to the world of gears.
GEAR.12      $29.95 kit

Worm Gears
Our worm gears come in 2 sizes, small (8 mm dia.), and large (15 mm dia.). Both are 25 mm long, with a 2 mm shaft hole that fits perfectly on our electric motors ELEC.13 and ELEC.45 as drive gears.
GEAR.01     Small (8 mm dia.), single                      $2.25 each

GEAR.13     Large (15 mm dia.), single                   $2.50 each
GEAR.14     Large (15 mm dia.), package of 10      $22.95/pkg

Cams
A cam is a "wheel" with a shaft hole off-centre to provide for an eccentric motion (up & down) as the cam rotates. Each "stem" comes with 4 cams: 1 small pear shape, 1 large pear shape, 1 off-centre round wheel & 1 step spiral (snail shell) shape. Shaft holes are 3 mm diameter, too large for our electric motor shafts, but can be used with bamboo skewers sanded to fit. Available in green, red, yellow or blue. Made in Canada.
GEAR.03     Whole stem with 4 cam shapes                  $2.00/stem
GEAR.04     Package of 20 stems, total of 80 cams       $29.95/pkg
