Longworth Chuck

thingiverse

This is a Longworth Chuck. It works by centrifugal force to hold pieces firmly in place on a wood lathe. A traditional example can be seen at http://bit.ly/1YpnUSK, which provides a more detailed explanation of its function. All components are securely attached with M6 machine screws that have the axle positioned centrally and countersunk for stability. This design represents an early stage, with plans to eventually cover the exposed cheese head machine screws with rubber or find alternative fittings that match the lathe's requirements. Print Settings: Printer: Chinese 80W laser cutter Rafts: No Supports: No Notes: A prototype of this Longworth Chuck was cut from 5mm MDF using an 80W Chinese Co2 laser cutter. Laser cutting settings may vary, depending on the specific machine being used. When importing Adobe Illustrator files (.ai) into lasercut software (version 5.3), proprietary configuration files and .ecp files are automatically generated. Users with different software versions should import the Illustrator files and adjust their settings through experimentation. Post-Printing: A lock nut is essential for keeping some tension on the axle, preventing it from coming undone during operation of the lathe.
