Our original model range, devised by Dr. Arnold Beevers, built on a scale of 1cm=1A in order to give models that are large enough to display the properties of solid state crystal structures, whilst being small enough to handle.
Ball and spoke models on other scales
Arising from the Beevers models, we now produce models using the same methods as those for Beevers ball and spoke models, but using larger balls and rods. Models can be built with balls of differing sizes.
Huge models. Although they were originally designed for large static displays for schools, itís up to you what you use them for!
