Elmer's Geared Steam Engine

[JMI]

Nicely done!
And thanks for the source for the gears.
Add this engine to my already impossibly long "to do" list :-\

Chris,
Do you recall how much the gears cost?
I have put this engine on my bucket list.

Sam, The internal gear was about $30.00 and the orbiting gear was around $15.00. I was very surprised how much they cost but without them...

A lot of us machinists can make external gears but without some type of broaching setup you're limited to purchasing gears of the internal type.

If I'm not mistaken, this engine is a hypocycloidal type, like the current Project Of The Month, only in a horizontal arrangement.

You're correct.

From the Greek...

epi- = outside (e.g., epidermis)
hypo- = inside (e.g., hypodermic needle - beneath/inside the skin)
