You will save a lot if you make the mounts for the ballnuts and bearings yourself. They all seem very overpriced to me...
Hello Jonathan
I was hoping to complete the project with my £500 pounds including the electronics etc, making the mounts ect will not be a problem, would a reasonable acuracy be achieved using threaded rod? not quite sure what you mean by an angled bearing do you have photos?
