Does anyone know of a website that sells rack and pinion assemblies, something along the lines of the vertical adjustment on an ohp?
Or does anyone have an old ohp and are willing to sell me the parts off of it?
The projector I am trying to build will be a vertical design that folds the light at a 45 degree angle; I am looking for a means to move both the mirror and the triplet vertically (both connected to the top of the enclosure), in a controlled fashion.
Any advice would be appreciated.
