Helical-Elliptical Gears - Neatorama

So what's so interesting about a gear made out of wood? Take a closeer look: it's elliptical!

Woodworker and artist Steven Garrison made helical (and helical-elliptical) gears using conventional woodworking techniques. Though such gears probably have no real world purpose, they are cool to look at in action: http://www.stevengarrison.com/id5.html (with embedded YouTube clips - don't miss the second one from the top) - Thanks Rob!

Also check out Steven's helix forms that fit together.

Mmmm... I suddenly have an uncontrollable desire for Reese's pnut butter cups...

Ha, beat me to it Dave. Peanut butter cup is the first thing I thought of when I saw this post.

That style of gear is actually useful for very specific applications where the speed needs to vary up and down in a regular cycle. Of course, they aren't usually made of wood!

Yeah, I guess they do sortof look like a reese's peanut butter cup :) Almost got my screen covered with chili when I read that!

I know that there are certain types of presses that use elliptical gears like Jonathan mentioned, but those are straight-cut rather than helical. I made these just to show that it can be done. I'm glad you guys like them. Please don't try to eat it LOL!

How do you eat a Reese's Peanut Butter cup? "I make gears out of them, turn 'em around a few times and then gobble 'em up."
