Brief

The request is for a chuck that can expand to grip the inner diameter of female splined shafts, while it rotates on their balancing machine.

The challenge is to improve their previous solution. They were previously using a “homemade” fixture. It had a slip-fit without the expanding capability to grip the inner diameter of the part.
