I am making a ball joint for a figure and have decided on ball bearings since they're easy to source in the correct size.
I need to attach the ball to a shaft of some sort, like a small steel rod.
The bearing will be small, approximately 1/4 inch in diameter. The shaft will be 1/8 inch or smaller.
The ball needs to be completely static and strong enough to support some weight, a pound maximum.
I have steel reinforced epoxy putty, but it's hard to work with and I can't imagine in sticking to the smooth surface of the ball.
I do not have tools to drill a hole in the bearing, and have not found pre-drilled balls of the right diameter for purchase.
What can I do? I'm looking to do this withing welding, soldering, brazing, or anything that requires high heat to accomplish.
