im trying to set my tub i put new floor down of 3/4 ply wood but the tub set in is like zero at one end an the other is about 1/2 inch to 5/8 inch difference dont think i can jack floor up so is this moter trick the best ...i had to get tub working and is fiberglass and creaks when you stand in it.
not good cuz i heard can crack easily????
the directions suggest shimming with metal plates instead of wood ??? moter sounds much easier!!!!....................help..Larry
