Steel. Not used but a little rusty from storage. Handy. Measures 3-1/2" dia with a single 1/2” ID sheave with a 2-1/8" x 1-5/8" dia hub and a keyed 1” ID bore. Drilled for a 1/4” - 16 setscrew (not included). Made in the USA.
But you’ll need a double pulley for that. Luckily, we have one right here. Double pulley, 1/2” dia with 3/16” brass sheaves inside a 1-1/16” long teardrop-shaped plated steel housing with a 3/16” hanger on top. Our Pulley Plenipotentiary says it’s perfectly capable of hoisting a good-sized plant up there to hang in your clerestory windows.
This nostalgia-prompting, zinc-plated aluminum single sheave pulley is made (and so marked) for a clothesline, which is what people dried clothes on before there were driers. If you had two of these, you could run a clothesline to the kitchen window of the tenement across the street and have something to tell your grandkids about. Measures 3-1/2" dia x 1/2" ID on a 3/4" wide x 2-1/2" bracket and comes with a 4" long x 7/8" ID J-hook for mounting outside the kitchen window.
Call it a vicious circle, this 1-3/8" dia white plastic gear with 58 teeth. Has two different input sides: (1) an 8-sprocket with a 3/16" ID, and (1) just under a 1/4" ID circle with a flat side. Teeth are approx 3/16" wide and whole shebang is approx 1" wide.
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.
