I made this for my nephew’s birthday. It works with a crank which operates 5 cams. Each cam pushed a piston each of which has a concavity in it to hold the marble while rises to be dropped into the next highest piston. The last piston is a slanted channel which allows the marble to roll down to the bottom where the process begins again. The added bonus is that the pistons can be removed and put back in easily. My nephew likes to take apart and put back.
I used three pieces of my drawer front wood. To me this looks to be white oak. In any case it’s Notpine. Everything was well sanded, but I left it unfinished. My concern was that any finish would make the moving parts stick together.
If a picture is worth 1,000 words, I figure a video showing the operation of this toy is worth 1,000 squared.
