If I mount an unbalanced piece of wood on my lathe, it causes vibration. i.e. I'm spinning an offset mass at a high rate of speed. If I add weight to the base of the lathe (e.g. sand bags, concrete blocks, bolting it to the floor), I can stop the vibration. My question is, where is the force transferred? Am I causing the lathe components, bearings, ect to accept the force? Or is the force absorbed by the extra weight (or the floor)?
