Gears, Gears, and more Gears

Came up with this idea after seeing a couple of cheap plastic toys that used gears. Like every other woodworker I said I can build one better out of wood and less cost. Baltic birch ply for the gears and base. Each set has one gear with a handle and when you turn one they all turn. The hard part was tuning them so there wasn’t any high points on the teeth that would stop rotation. Turn the crank and when I felt resistance remove the gears one by one until I found the offending gear. Sandpaper and rasp until they turned smoothly. They sit loose on dowels for the axles so they can be taken off and put in any configuration the child wants. I was thinking of painting them different colors but in the end I thought that natural finish looked better. For the impossibly cute grandchildren.

That is a very cool project. I’ve always kind of wanted to try a wooden gear clock one day. Something like this might be a good way to ease up to that. You did a nice job on it.

Well done. Like the natural look with very neat designs. Amazing that you can get all 16 gears to turn smoothly. About how many man hours per 4×4 set?

Great job. Now you’re really “geared up” for your next project.

Nice work Green Hornut!

You can make your own gears from the link above as well.

I have been looking for something for my granddaughter, and a project for me, and this one looks like a potential winner!

Did you cut the gears on a jig saw?

I was thinking about using a large dowel, flute it, sand it, and then slice the gears off with a TS!

That’s a great learning toy for kids. I’m sure your grand kids will play with it for hours.

Mike, that toy is exactly what my grandson has and what prompted me to do this project. Wood is better any day of the week. Plus there is some creativity in moving and cranking the gears. Not sitting and watching them move because of a battery.

Charles, Ya they look great but they are also selling them for 2 yards. I have probably 20 bucks in Baltic birch ply. Also I would like to try something like that but they aren’t sharing their pattern.

waho6o9, that is exactly were I got my pattern.

Thanks for comments folks. Nice to see people looking at your stuff.
