Touch Probe

[claudef]

These are the parts I machined today, the probe is finished except for the spring c-bore. The ball ring is complete except the OD needs to be reduced for final adjustments. The balls are wired and ready to get pushed in their cavity, the have a .002 press fit but the center of the balls only go .010 below the top surface. The ring material is PTFE, not much sticks to this stuff, I am wondering if crazy glue or locktite would secure them. Any ideas are welcome. The soldering of the wires went relatively well, better than expected, I ground a small flat on the ball and used a soldering pencil.
