Using the center column for azimuth motion on the Bogen Tripods (even the older ones) doesn't work well anyway, imho. There is a rubber o-ring that causes sticky motion and the locking system isn't adjustable enough anyway. Most alt-azimuth heads have a built in azimuth motion anyway. If yours doesn't then it wouldn't be that hard to make one from some teflon, laminate, thin plywood and a bit of hardware. Also, there are well made panning adapters made which will provide smooth azimuth motion, you just need to find one without click stops. Hope this helps.
