I saw a post a while ago about building gears from scratch by cutting slices off of a pen/marker cap that had ridges. When you do that the slices become gear-shapes. I dont really have access to something like that (believe me i checked all my markers/pen's/glue bottle tops/etc), does anyone out there know another way to make decent gears without buying pre-made ones or salvaging them from sprues or something else where its already been made for you?
I have access to basic styrofoam, cardboard, lead slabs(although they're a little thin, i did make some really nice machine pieces from it though), and all kinds of odds and ends and craft supplies.
Also, as an extra, although not as important, can anyone give me ideas on how to possible scratch build a satellite dish?
Thanks a lot for any responses, ive been trying to make them out of cardboard and they're just terrible ><.
You haven't specified what size you're looking for so I'll be as general as possible
Plastic gears (and conversion bits in general) can come from anywhere. Model kits, cheap alarm clocks, toys, discarded tape cassette players and TVs.
The SM Rhino comes with a satellite dish. Cut ping pong balls in half. Keep an eye out for things that could be used.
actually i thought i was pretty specific. I'm trying to make gears from scratch, obviously scale gears, from materials i have at home. As i said above, someone took a pen cap with ridges on it, sliced them off perpendicularly and when you do that it turns the slices into gears because of the ridges on the pen cap. Something like that process is what im looking for, the wealth of knowledge on this site is pretty large so i figured someone would know some way of making decent gears without salvaging them.
the only thing that you offered that was actually making something was cutting the ping pong ball apart. I could go into my very old gi joes from my childhood, and chop them to pieces to get a satellite, but i dont want to do that =). I'm trying to use cheap materials that dont matter and turn them into something i can use.
Thanks for the suggestions though.
Step 1. Go to your local watch repair shop.
Step 2. Beg.
haha, thats another good idea . Still the problem of finding a watch repair shop, which i dont think i have near where i live.

Try to find a old laser printer or ink jet printer or something like that. They contain a wealth of plastic/metallic bits that are to "scale" in 40K, of course depending on what size of gears/cog wheels you're looking for (as the come in a multitude of sizes in real life, it's hard to know what you mean by gears "to scale"), why make something when it's already done for you?. Hope it helps.
well i dont mind salvaging parts, but if i can figure out how to make them, in a uniform fashion, in the size and shape that i want, that would be much better. Even if i do manage to have something on hand that i can rip apart to get gears out of (which i dont at the moment) they might be too big, too small, i can always find ways to use them , but if i need a couple of small gears for a suit of armor, or whatever, how do i get them then?
I dont really have to ask what can i salvage gears from, if i have something thats broken or used up, and i can tear it apart, its already been done. If i got some gears from that, cool, but if not, how do i get the gears i need? That leads back to the main point, trying to find a way to make them.
As i said , another poster found a way to make gears with marker caps and slicing them into thin sections, and it worked great. If i could find a way to do that with some more common material , that would be amazing, and the whole reason i made the post.
thanks again for the suggestion of the ink printer catridge, i tore apart one from my work(one of the large ones , not just the ink holder, the entire bar that actually prints the ink onto the paper.
The only way I can think to do it without salvaging...
Starting with a clean bit of Cardstock,
Find your center point.
Make a circle with a compass as large as you want the outer diameter of the gear to be.
Make a circle one eighth inch smaller.
Draw 12 lines through the center point evenly spaced so that they go all the way from one side to the other. In this way they should form the sides of the teeth.
Cut this one out by cutting inward toward the center. What you want to end up with is a template you can trace, not a finished gear.
Once you have the template cut out you can trace gears all friggin day on plasticard.
Then cut them away from the center so you have a nice gear in the end.
Either that, or try your local thrift store to see if you can buy an old watch, and cannabalize the small gears from that. (or buy new ones if you can find ones for reasonable prices)
I'm looking for a good source of small gears myself, being an AD-Mech fanatic. So I am intreseted to see what you'll come up with.
Hope that helped!
