Converting a Mini Milling Machine to CNC

With This book, any person with basic milling skills should be able to convert a mini milling machine to CNC. Written with the hobbyist in mind, the conversion process is designed so that parts are fabricated on the mill before disassembly. Work required while the mill is disassembled can be done without a second mill. The project is fully documented in plain language with additional detail provided by photos and drawings. Glen describes disassembling the mill, selecting ball screws, modifying and fabricating parts, and adjusting the machine. Drawings are provided for two different mini mills. Drawings show modifications to original parts and the parts that must be made to complete the conversion. Glen discusses potential differences between models and provides insight into how to prepare and measure for variance between different manufacturers. This conversion will work with SIEG X2 style mini mills: Harbor Freight model #44991, Grizzly Tool Model # G8689Z, Hi Torque 3990, Eastwood Benchtop mini mill 4x16, and many other models sold by tool distributors.
