Cheap gears

Have them laser cut. Cheap, quick.

Maybe get a set or two outta an old photocopying machine. There's lots of gears, chains, sprockets, etc., in one of those... Ken.

watch for wrap in the long URL

I have a friend who needs a couple of sets of cheap gears - basic, flat, spur-gears in pairs. Bore ID could beanything, 1/8" & up.

He has an idea that he wishes to test and we thoght about hobbing a set or two, but for all the use they are going to get, even plastic would work right well. Don't need to be overly durable, just more-or-less functional, to test his (not mine - I swear the damn thing will NOT work - but you know how ya will do dumb stuff for a friend) hypothesis.

Something in a 4" - 6" OD, thickness could be anything from 1/8" on up.

Any ideas???

Thanx,

And so fast, too. Sorry I reposted,

What about trying "spirograph"

Masonite and a bandsaw? Cheap CAD and a laser-printed template?

shows some 4.75" and 5" nylon gears for about $11 each. (Also see the url I mentioned in "WTB: 32DP gear rack" thread, ) Haven't ordered anything from them so I don't know shipping costs etc.

You might want to consider plastic sprockets and toothed drive belt. Cheap and less fiddly than gears

A water cutting machine would do that nicely. Martin
