I am new to this site and totaly amazed at the helpfulness of its members! Has anyone built a Harmonograph? Just for kicks and grins I have started one out of mesquite. I am going for the classy look with brass and exacting craftmanship (as much as possible for me). There are alot of quick science project types out there made of construction plywood and nails but this is not what I am after. I have reached a stalling point now. I am trying to come up with a design I can build for the two pivots point through the table. Each rod must swing on two planes(hope I’m describing this correctly). I want to make these pivot points out of wood but just havent worked it out yet. I’m looking for any advice and especially pictures of members Harmonograph projects if any. I will post some pics here soon of what progress I have made.
I coudnt figure out how to re-size the photos so that the whole image would show here but you get the idea of what your seeing (I hope). As you can see I have what I thought would work but I just cant get the rings and pivot points lined up (and stay that way) when weight is added to bottom of pendelum. Its set up now with brass rod and nylon bushings. Any help with some ideas or advice would be appreciated.
