Gears Go-Round: from Make Magazine Online
Make Magazine is one of the best Do-It-Yourself Online "Popular Mechanics" Zines around...
They cover lots of different fields, technologies, materials, tools, skills, gizmos, devices, etc.
Here is a recent Round-Up "Top 10 Gears Projects" for you to consider and Make and Do...
"Gears Make the World Go Round..." is Geometrically True and that's a very High Standard of Truth :-)
A scrap pile of gears can be a goldmine for a "tinkerer"... wheels, wheels, wheels, and whirlygigs...
2013 update: This website is dedicated to illustrating (largely and clearly) and animating the classic book from Dover Press "507 Movements" (gears galore etc.)
very kool...and in development ...look for the pictures highlighted in color for the animations they have accomplished so far...
here is No. 24 animated:
And when you clear a workspace, and begin with one handmade wooden gear... that connects with another one...
Now you have created Mechanical Magic...and Things start Moving... for Real...
If you scroll down the Make Magazine Top 10 Gears Projects List... to #1... This is what you find... :-)
Because Simplicity is How You Begin...One Gear at a time...
which leads you to the Awesome New York University Free Course online "How To...Guide"
with this link:
"We asked Dustyn Roberts, who teaches a course at NYU’s Interactive Telecommunications Program (ITP), called
Mechanisms and Things That Move
, to contribute something on fabricating your own gears for our
Physical Science and Mechanics
theme. Dustyn has written a book, called
Making Things Move
. It’ll be out in the fall and we’ll have more about it, and likely a giveaway, then. Thanks, Dustyn! — Gareth
Gears are easy to understand, make, and use, if you know the vocabulary and can space the gears at the correct distance apart. One nice thing about gears is that if you know any two things about them – let’s say outer diameter and number of teeth — you can use some simple equations to find everything else you need to know, including the correct center distance between them. First, look over the anatomy of the spur gear pair in figure 1 and the vocab below."
