Knex Rack and Pinion? Answered
Hey Guys and Girls,
Recently I ran across an old prototype of a knex rack and pinion I made a long time ago. I was curious as to if there have been any other rack and pinon designs shown on the site of maybe that have been used in a project.
Second: Would anybody have any interest in seeing the design before I take it apart? Any Ideas of what it could be used for?
