I am looking at building a marble run this fall or next fall and am starting to look for "how to build" sites. With some different examples of marble runs.
Some of the parts of a marble run would be standard flatwork, but there are some opportunities for turned funnels where marbles are collected and dropped, also for parts of the marble life.
Does anyone have any good references for building marble runs?
Edited: Marble run may go by several names, something like this is what I am looking for https://woodgears.ca/marbles/build.html
Thanks
Michael
