  • Big Balls, i.e. turret rings

    Okay so I trashed a new set of upper and lower turret rings this tear. A very expensive lesson. Last spring the turret on 18 was flopping up and down. So much so that it wore a hole in the five pin chute from rubbing on the front side of the halo ring. At the time I replaced the rings cause they were badly worn. Now after overhauling the turret this week the new rings were also worn. As it turned out there were about 15 oversized bearings in the outer ring. Miked out at .3783 vice .3750. Where they came from I don't know. The questions are has anybody ran into this? How critical are the sizes, apparently very critical. Also brunswick sells carbon coated bearings vice chrome bearings. Are they sacraficial to save the the rings? Since they are softer then the chrome ones.
    Thanks, jacks

    Not much activity on this thread.
    I certainly understand why. I would suppose that the turret in question had been rebuilt before. Most probably whomsoever rebuilt it went to the bearing store to replace the balls that were lost running down the gutter, when they did'nt pay attention to Dr.Pepper, IE, ten, two and four. My guess is that the bearing store had some 9.6 mm bearings in with the 3/8 stock. As to low carbons, it's my understanding they are less subject to brinnelling and the resultant flakeing common to high carbons. I feel its a mute point however, as many turrets are still running strong with ten million lines on them, with a minimum of upkeep.
