Re: Plans for a sphere machine
Tim, as Bob indicated, a good starting point is the Yahoos Spheres Group. Not only are there some professional and near professional spheremakers posting there, there are also quite a few amatuers that have build their own machines. Many pictures are posted there so show you what others have done. The motors usually used for sphere machines are gear motors running around 100 rpms, not your typical 1750 rpm motors. Several sources for gear-motors are posted in the Yahoo Sphere Group archives.
