How to Bore Soft Jaws on a Lathe
Soft jaws for the lathe chuck are a very useful workholding tool, particularly for holding circular objects that might be crushed by hard jaws. Often made out of mild steel, or even softer materials like aluminum, these jaws can be machined to grip the object around most of its circumference allowing you to maximize the grip.
In order to get the most out of your soft jaws, it’s important to know how to bore them correctly. Luckily the process is pretty simple.
In this video provided by Meridian Community College, Brian Warren and one of his students demonstrate how to do it.
