lathe spindle lock

thingiverse

This clamp ensures stability while working, providing a firm grip for light duty tasks on stationary workpieces. Though not a true lock, it offers strong resistance and can be used with an indexing mechanism. It may require experimentation for certain operations like milling. The print takes around 2 hours to complete and uses 45 grams of material. To install, drill and tap two attachment holes into the headstock casting using a #9 drill, going 20mm deep and tapping for two short 6x1mm bolts. The holding band is designed narrow enough to temporarily park it out of the way behind the standard chuck, allowing for convenient use without removing the lock. However, it's recommended not to leave the lock on during daily operations for safety purposes.
