Hello, longtime lurker here. Please excuse the somewhat n00bish question; however, I've been an admirer of steampunk for a long time but it has taken me until now to try and tinker with a design for my self.
I do love the look of gears, but I'd like them to have a function, move, and not just be static and though I've scoured the web quite a bit I haven't been able to find a site that explains the proper or best way to "hang or set them"; please excuse my choice in words too, I'm not well versed in the technical terminology. I'd like to know if you could direct me to a site or pictures on what is commonly used for pins that hold them, if there's washers involved, some kind of shafts around the pins, how does one "set them" so they don't rub against the wall holding them, etc.?

Thanks for any advice guys. I just feel so excited to have decided to finally tinker with a design and would like to at least try and do it to the best of my ability with the help of experts.

I've bumped this up to Tactile main because I think it will get more exposure here. How To was really intended for giving advice more than asking for it, and I really need to do some cleanup there.

Do some searches for automaton. You should find sites that have plans to make wooden cogs and gears for simple automaton. That would get you started. There are kits out there for making such things. This site is a good start; http://dugnorth.com/automaton-plans.aspx 

I know it is difficult to search for things when you don't know the words you need to search! There are some really lovely automaton that use brass gears and cogs. Good hunting.

Hello and welcome!

I wondered about this until I wandered onto some watchmaking pages - I always thought I would never be able to make anything
as accurate as a clock by measuring, marking and cutting* - until I discovered that , as in most things, there is 'cheating' going on...  Grin

For gearing, look up - 'depthing' - here, the first pinion is set, and the second moved about until the right mesh is involved. This distance is then used to mark out the holes. Clever!

See this marvelous Youtube series for much educational brass clockworking :-
This one is about depthing in particular but all are worth watching.

I like the idea of moving gears very much too!

I you want to keep things simple and depending what you want to do, there is always the option of including all of (or nearly all of) a clock mechanism in a piece. In my jetpack I have moving gears, this is simply a clock mechanism with the springs and escapement removed, I have driven it using a cassette player motor and drive belt looped around one of the clock shafts.

Thanks for the tips, links and moving the topic, guys. That automaton link with the clocks in particular was good!
I'm slowly starting to pick up some ideas and learning more of the terminology. That depthing tool looks really handy, and definitely something that would help measuring things correctly!

I guess for something small i'm making though, basically just a couple 5, 6 gears, *anything* could be of use? I don't have any clock parts (except the gears themselves) so I was thinking of just threading anything straight and metal that would fit through the hole as a shaft and maybe "close it off and hold the gear in place" with something like a rubber washer or something else that could hold it in place?
