Grinding a cam for a model internal combustion engine can be a tough job. Using a computer controlled cam grinder is an attractive alternative to hand filing cam lobes, assembling multipart camshafts or building a complicated mechanical grinding machine. Joe Martin has created a CNC (Computer Numeric Control) cam grinder using mostly off-the-shelf Sherline machine tool parts along with a g-code program he developed himself. This video details the production of a cam for a Howell V-4 engine being produced by the Joe Martin Foundation Craftsmanship Museum. To learn more about the engine itself go to www.CraftsmanshipMuseum.com/HowellV4.htm . For more about Sherline miniature machine tools visit www.sherline.com. This is part one of the video. Each half is about 9 minutes long.
