Granite Precision Slab




This had to be the most challenging piece of the whole lot. A 6,000 pound granite slab for precision measurement calibration in a machine shop. In our first picture you see the stand used to hold the slab while it is being used on a daily basis, although for shipping we cannot use the stand to support the piece during the shipping. We must remove the slab and put it on a heavy duty skid and band it to the skid with blocks to prevent it from moving around on the skid. After placing it on the skid we must clean the surface a apply the plastic sheathing which will be not only a moisture barrier but a dust shield, against stray dust which may affect the measuring surface of the granite slab. Once the protective sheathing and cardboard is in place we will begin blocking and banding. At the top you will see the soft crate finished. The sides are exposed but with the blocks extending the sides by an extra inch and a half that will give us the confidence we need to know that the sides will not be affected by anything shipping next to it.
