I have built a workbench out of solid maple boards with a 3-inch thick top.  It is sitting top side down on a pair of store-bought trestles in my garage.  My problem is that this bench is much too heavy and awkward to lift off the trestles, turn over and set down on the floor.  I am leary of using a lifting frame for fear of bruising the bench aprons with the lifting straps and even then I don’t know how I would turn the bench over.  I have not yet connected the base to the top.  Would it be better to move just the top and flip it onto the base?  How about just hiring somebody – movers with strong young backs perhaps, to do this?  Any advice would be appreciated as I am almost at the critical juncture of needing to do this.
