I decided to use my Beall collet chuck for the first time, today, and I must have slept through a lesson. I wanted to chuck up a mandrel with a .298 diameter. The collets that came with the set include a 1/4" and a 3/8". Clearly, the 1/4" is too small, so I tried using the 3/8". I tightened it up, but it came nowhere close to gripping the mandrel. What am I missing?
