Wooden Escalator Fit For A Slinky

Our favorite mechanical master of woodworking, [Matthias Wandel], is at it again, this time making an endless staircase for a Slinky. Making an escalator out of 2×4’s and other lumber bits looks fairly easy when condensed down to a two and a half minute video. In reality a job like this requires lots of cuts, holes, and a ton of planning.

The hard part of this build seemed to be the motor arrangement. There is a sweet spot when it comes to Slinky escalator speeds. Too fast, and you’ll outpace the Slinky. Too slow, and the Slinky flies off the end of the escalator. Keeping the speed in check turned out to be a difficult task with the coarse speed control of a drill trigger. The solution was to ditch the drill and build a simple hand crank mechanism. The Slinky now can cascade down stairs as long as your arm holds out.

Join us after the break for 3 videos, the making of the escalator, a 140 step demonstration video, and a followup video (for geeks like us) explaining where the idea came from, whats wrong with the machine and possible improvements.

Thanks to [Jim Lynch] for the tip
