I received a notice from my daughter’s school looking for silent auction donations for an upcoming fundraiser. The funds were going towards the school’s parent council and are to be used to fund programs, and purchases, not covered by the schools budget. I thought it would be fun to donate something that was hand machined in hopes that my labor would score a decent bid and therefore increase the funds collected from the auction.
I wanted to fabricate something that would appeal to a wide audience and so I settled upon machining a yo-yo. I figured both kids and adults could enjoy the pleasures that come from rotational energy. The yo-yos I build are not pro style trick units, they do not run ball bearing axles or friction pads. The units I make are for the pure novice that can appreciate the joys that come from classic design.
The first order of business was to change the name. Although yo-yo is a generic, non-trademarked, name I felt it was too immature. Therefore instead of machining a yo-yo I opted to machine a Vacillating Vertical Pendulum. The concept is the same, only the name has changed.
Since the pendulum will be placed on an auction block I opted to machine a custom storage case for it as well. I have posted pictures of my “yo-yos” in the past but have not dedicated an entire post outlining the process. The following is jam packed with pictures showing the procedure I have developed to make a Vacillating Vertical Pendulum.
