description About
Norm considers a historic example of the classic marble roll, as well as a huge mechanical version located at Boston's Museum of Science. His own design emphasizes safety, proportioned for marbles too large for a child to swallow, while the entire unit is small enough to be portable. It is a relatively simple project, made primary on the table saw, that can often be constructed from workshop scraps.
