You can make a gear really easily on a regular bridgeport milling machine (basic gear).. However for most teams who don't have a bunch of people working in a machine shop, or team that dosen't have the cutting tools and kids like me who could do it, it's easier (probably cheaper) to go to McMaster Carr..
They're refering to last year they taught the girls how to make nuts and bolts useing lathes and I'm assumeing a milling machine (could make a HEX shape on a surface grinder but I doubt they'd have kids useing those in a summer camp)
