My uncle wants to make some wooden gears as used before the days of metal. I
haven't had any luck googling and I gave it a hard try.

The project includes powering the gear train with a hit and miss engine to
show at an old engine show from what I gather.

Anyone have suggestions on resources?

Thanks,

Wes

Take a look at http://www.clockplans.com/

If that doesn't tickle your uncle's fancy, google "wooden clocks" and
you'll find a bunch of others. I know of no current wooden gear makers
that aren't doing clocks.

Good luck.

Metal has been used for what, 2-3,000 years? Might be a bit more
specific. If he just want's them for show, be simple enough tocut out of
plywood. However, if he wants wooden gears loke those that were used
to do actual work, take a look at some of the old mills, sawmills, etc.
Water wheel power, all wooden gears. Personally, with a hit-and-miss,
I'd go for metal gears. Those were used in boats too, so maybe a prop.

Ask the engineering groups about tooth profile. Efficient
cogs are designed to roll against each other to reduce
friction.

American clockmaker Eli Terry used solid cherry and
produced clocks that ran accurately for 100+ years.
