A year ago Creatables came up with a miniature inclined Slinky treadmill. Sadly, it appears the toy never made it into production. But one of our favorite woodworkers Matthias Wandel came up with a DIY and hand-powered alternative.
Matthias’ slinky machine is a hand-powered escalator. He tried to power it with a drill, but he found it hard to control the tool’s speed. Thankfully his wife Rachel came to the rescue and suggested he use a crank instead. Problem solved!
If I had this I think the noise would get to me before I got tired of turning its crank. Head to Matthias’ website for more on his project.
