SKU: 152985 50 Caliber Cartridge Twist Pen Kit

This pen will be popular with military enthusiasts and outdoorsmen. It is made from an authentic 50-caliber once-fired brass cartridge and features a 7mm tube and a Cross™ style ballpoint mechanism. This one of a kind project is easy to make. The length of the turned section can be varied from 1-1/8" to 2" for a custom apperance. This project is turned on our standard pen mandrel with the 50 Caliber bushings sold separately.

Bushings: Bushings are needed to turn the project on the pen mandrels we offer. The bushings are used to size the outside diameter of the workpiece correctly for the specific project. They are also used to adapt the pen mandrel for project tubes larger than the mandrel shaft. Only one set of bushings are needed for many kits. After the bushings are worn down from sanding they will need replacing.
