lathe Chuck plug

I recently acquired a 125 mm three jaw chuck for my lathe, but unfortunately, it lacked a crucial back shield that protects against chip buildup. To address this issue, I decided to modify the design by incorporating a rubber band on the outside of the chuck. This simple modification helps seat the chuck securely onto the bore and prevents chips from entering through the o-ring seal. My SANOU K11-125 chuck has been performing flawlessly so far, without any need for additional fasteners to keep it in place.
