[CAUT] unmusical caster noise

[Loren Buntemeyer]

If there is lots of slop between the caster and plate that bolts to the truck, you will get movement and strange noises.  Locking the wheel will not solve the problem.  When you take the caster off or take the weight off the wheel, check the side play of the wheel and the unwanted slop when it turns on the bearings.  Usually you can't correct this problem since it is stamped together except maybe a heavy lubricant on those dry bearings or new casters.  Even some new casters have to much play.

  All,

   

  The rear concert caster on one of our Ds "knocks" and I can't seem to find the "fix". If we orient it 90 degrees to the player it doesn't knock, but if the stage crew forgets and it is in line with the player it will knock with vigorous playing. (Fairly loudly, like someone tapping their foot.) The leg seems to be tight. It is the actual wheel. It is the big expensive brass kind, but unfortunately not Jurgen's. Any simple fix?

   

  The front castors lock (and have no problem) but the rear doesn't. I can't see how/where/why it is knocking, but it surely does.

   

  Thanks.
