Thanks for that thought. It seems the ball would not have to be attached if spring pressure was sufficient to cause the ball to rotate when the vernier shaft was turned.I thought it was attached after reading Philco service hint 39for model 38-8 which shows the ball attached to the shaft. Perhaps both versions were used.I'll try to get it to work unattached if I can straighten the pinion gear shaft.
