Where can I find a BASIC tutorial on mounting and installing small gears? Answered

I can program easily because there are tutorials on everything. I'm looking for something similar for dealing with mounting small gears on axles or shafts. I have 12V motors and various small gears and axles salvaged from printers, but can't find anything for someone who doesn't yet know the terminology. For example, where does one buy the little thingies that click into creases on axles to hold them in place? Where does one find axles with part of the edge ground flat? Etc, etc.... Thanks.

E-clips? Look like metal 'C' with a tab inside to make an "e" shape and little holes (for a special pliers) on the ends, snap into a grove. hardware or automotive stores are where to start. Radio Control (RC) stores are going to be more expensive just because they are a specialty store. Cut the axle to length, then grind a flat spot with a dremel stone bit. A search with the word 'glossary' or 'faq' usually helps.

Thanks! This is helpful, and it also sounds like a good idea to add "glossary" to my search strings. It would be great if there were a book or even a pamphlet that went into this -- I can't be the only one feeling lost at sea around these questions.

Oh, and so does the image search in google.

Thanks! Doing an image search on e-clips shows these are what I'm looking for.

Those little things are called "keys" they fit into "keyways". You can get some at any good hardware store or lawnmower repair. Those are probably too large. Look to hobby shops that cater to R/C cars especially and also helicopters. The keys they have are going to be much smaller and closer to what you want. They might even have axles/shafts and bearing the size you need. Make friend with the guys there and at a good hobby shop the guys there will be falling all over themselves to help you on a good new project. Next step is to get onto the interwebnet and look for the parts you need there. Keys are not expensive but sometime hard to find the right size.

Its hard to do, because there are many ways to do it. Flatted shafts I'd make myself with a file or milling machine.
