I working on a design for a lathe stand. I thinking of using 2x4s with a 3/4" top and shelf the size I'm thinking about is about 30" high 28" long and 12" wide. I'm thinking about uing double 2x4s with a 3.5" step top and bottom for the uprights threr would be two of these on each side. This design would be fairly heavy and I think this would be a plus... my thoughts are this weight should help dampen vibration or am I wrong. I dont have any think drawn out just a picture of it in my minds eye.
