Variable height desk: replace hand-crank with some kind of electrical motor Answered
First time poster here, sorry if I'm misplacing this. I have near zero knowledge of engines, though I understand physics, at least from my civil engineering college years.
I bought a variable height desk from IKEA (Skarsta model), which has a 12cm radius hand crank (see photos) that ends in a hexagon shape, h=6mm (so diameter around 6,93mm).
This hand crank works fairly easily, needing little effort to crank the table up, with ~45kg of weight on it (it's supposed to go up to 50kg).
So basically I was thinking if there was a easy, cheap and safe way of automating this with some sort of electric motor (I even looked up those Lego Technic motors!).
