Maybe some pics would help. What Frank is describing is a basically a homemade Lazy Susan setup where you have the base of the turret sitting on three or more rolling elements. The turret base is maintained in its center of rotation by a shaft attached to the turret base and going through a bearing assembly in the top of the tank hull. This shaft can be as simple as a bolt as in my Cromwell or something hollow as the pipe described by Frank for passing wires between the hull and turret. A nut, shaft collar, or sprocket/pulley is then used to lock the turret in place.

Running into the Naverone gun at full speed did only superficial damage to the Cromwell’s turret cover and none to the turret mount: http://www.rctankcombat.com/archive/2007-04/jpg00103.jpg Rolling off of a ledge onto the turret did no damage whatsoever: http://rctankcombat.com/press/TankExpo2006/08CromwellRollover-large.jpg Another source for “transfer ball rollers” https://www.surpluscenter.com/item.asp?item=1-3501&catname=wheels Steve Tyng -- You are currently subscribed to the "R/C Tank Combat" group.
