A couple of days ago my son came by to share his big news—He and his wife are going to have another baby. My son will graduate from University of New Mexico with a Bachelor of Science in Mechanical Engineering in December, 2013. His wife will also receive her Associate of Applied Science from University of New Mexico in December, 2013.
So, as an excited Grandma, I needed to make something to celebrate the occasion. This son already has a little boy, Michael. So I came up with this Fabulous Gear Thing to celebrate: A toy for the soon-to-be older brother, Michael, and the soon-to-be mechanical engineer and his wife.
I started with a piece of wood, in this case a scrap of poplar.
Then I used Matthias Wandel’s Gear Generator program (available at woodgears.ca) to get a template for cutting the gears.
Then I did the cutting, sanding, glueing, you know the drill. (hahahahahahahaha—pun very much intended)
I did the big reveal. You can turn the crank and spin the gears, or you can flip the gears with your finger. Little did I suspect that my husband, a civil engineer, and my son, the almost mechanical engineer, would have their heads together discussing the degree of torque, how much force, etc. etc. generated by this little toy. Michael just turned the handle and thought it was fine.
Here is the little boy who started it all, my grandson. Yes, I know, I know. No one thinks grandkids are nearly as cute at the grandparents.
