Application: Z axis Counterbalance for Miniature Milling Machines
The Home Shop Accessories constant force air spring will solve all your problems with Z axis counterbalance in a very inexpensive, compact, efficient, and fully adjustable package.
(Using an inexpensive air cylinder and a soda bottle!)
The 4 page, full color plans describe the construction of a constant force spring that will counterbalance any load from 1 to 30 lbs or more under dynamic conditions. Mounting options are wide open and depend on your machine and requirements. Can be made to work with any mini mill. Sherline, Taig, Harbor Freight, Import, or whatever!
