Shopsmith Disc Sander Table Insert NOS

Made of die cast aluminum alloy with an elongated slot and a beveled underside to allow for sanding with the table tilted.  Useable on the Mark 4, Mark V 510/520, and Mark 7 machines.  OEM NOS brand new.  Shopsmith L.P. no longer offers this item.  I have a limited supply of these inserts.
