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

  • 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.
  • Glue the big ring to the back. Make sure to line it up exactly.
  • Using the bolt as a giude, glue the sun gear to the handle. Make sure the radial holes line up.
  • wait for the wood glue to dry. You don't want to glue the plaentary gears to anything by mistake.
  • Put the bolt up through the bottom.
  • Line up the three planet gears around the outside spaced evenly.
  • gently lower the handle and sun into the middle.
  • 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.
  • wipe off excess locking compound and let the glue dry before turning the handle.
