The other day my Lyman tumbler thumbed its' nose at me and walked off the job. It was probably offended by my using it for the ignominious task of burnishing jewelry when all the while it was destined to bring about glamour in shell casings for ammunition.
It has always been my understanding that a vibratory tumbler designed
for polishing brass is not suited for processing a heavy load like
rocks or metal shot. The offset weight that provides the vibration is
too close to the shaft and will not supply enough vibration to turn
over a heavy load. I bought my tumbler from a reloading supplier and
had to send the first one back while they shipped the correct model.
The advantage of a VibraSonic or MiniSonic is that the vibration
intensity is variable. I have not used my MiniSonic yet but the large
Thumler vibratory works fine.
