I've been creating parts for my forth coming gear zine. If you've been following along you'll know I'm planning to use photographs of paper gears to illustrate how different types of gear mechanism work. I'm also planning to provide links so that readers can make their own gears to try them out first hand.
It turns out that the design process for bevel gears is an interesting process and will be rewarded with its own blog post shortly. I settled on an 18/24 teeth gear set.
Shown here are the inner supports holding up the cone of the 24 tooth gear.
...and here are the actual teeth.
The two parts fit together to make this rather satisfying gear.
Both gears meshing together. I'll be putting together a downloadable project of these parts shortly.
