Re: Real vibration resolution...shaft drive.
I checked the gearbox on my 4" angle grinder. The ratio is 4.5 to one. Coupled to the chinagirl with it.s 5-1 ratio, final ratio would be good.
Just need to find an adaptable 1-1 angle box to replace china's sprocket and mount the grinder box at rear with live axle mod.
