Description

Gearbugs are toys built from gears. Gearbug #2 a planetary gear system built to be turned by hand. Oddly addicting to sit and turn. Requires a single M3x12 bolt and nut. You can see what it looks like in action here: http://authenticinvention.com/images/gearbug/GearBug2sm.gif

#1 is actually still being worked on. It's the one with the outriggers. It doesn't need glue but I am not yet happy with it.
Very cool. Where's gearbug #1?

Instructions

<ul> <li> Cut out all the parts with a laser cutter from 1/8th inch MDF or plywood. The file is in Inkscape format. I cut black first, then blue then red. <li> Glue the big ring to the back. Make sure to line it up exactly. <li> Using the bolt as a giude, glue the sun gear to the handle. Make sure the radial holes line up. <li> wait for the wood glue to dry. You don't want to glue the plaentary gears to anything by mistake. <li> Put the bolt up through the bottom. <li> Line up the three planet gears around the outside spaced evenly. <li> gently lower the handle and sun into the middle. <li> put some thread locking compound on a nut and thread it on. It need to be flush with the top of the screw. Not too tight, not too loose. <li> wipe off excess locking compound and let the glue dry before turning the handle. </ul>

<p>Very cool. Where's gearbug #1?</p>
