know what machine(s) they might fit?

Well ... the 40:1 ratio is a common one found in index/dividing
heads, so if you want to make an very good one, that might be an
excellent starting point. Most people who want to build their own
dividing head are scared off by the prices from Boston Gear.

What is the OD of the big gear, and the ID as well? It might
have to be bored out a bit to allow a reasonable spindle to pass through
it.

Enjoy,
