Gear Up
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
Or gear down-for the science fair or for any number of hobby projects. This hard-to-find set of (3) combination spur/beveled gears-for when you want gears set either straight or at 90° to one another-also has one small spur gear, plus three bushings. All in red, green, or blue plastic (we'll pick). The combo-beveled gears are 1-5/8", 1-1/4" and 27/32" dia with 3/16" bores to accept the bushings, which are 3/16" OD, 3/32" ID. The straight gear is 17/32" dia with a 1/16" half-bore. All are 24 pitch.

Hello Dolly
Good-bye backaches. Save your sacroiliac with a 3-wheeled professional mover's dolly. It measures 6-3/8" wide between a trio of swivel casters with 1-9/16" x 11/16" wheels, and has a drop-down center and a 1/2" dia hole for permanent attachment to frequently moved items. Steel construction, 110 lb max load (so not piano-duty), and rubber pads above each wheel. Stands 2-1/2" tall. We think ordering (4) would be a good place to start.

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.

Burn Rubber…Maid
These hard, black-plastic wheels are from Rubbermaid®, made, we think, for wheelie garbage bins, but available to you for to add wheels to whatever you want to roll. Measure 6" dia x 1-3/4" thick with a 3/8" axle bore standing off 5/8" on one side and countersunk 1/4" on the other. They're hollow and very lightweight, so they're ideal for homemade kiddie vehicles or wagons.

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.
