The Total Shop used 1.675" Way tubes. Since no repair parts exist for the total shop, I have sold Shopsmith headstocks that will fit on the total shop tubes and tighten down with no lost of accurancy. I have several spare total shop main tables with a side extension table and the front miter gauge extension. The miter gauge slot need a light milling to accept the Shopsmith miter gauge. It would be just as easy to mill the miter slots to accept the 510/520 Shopsmith miter gauge. The total shop main table trunnion legs will fit the Shopsmith 500 carriage. My headstock repair jig uses the smaller total shop tubes, base and base arm to allows much easlier access to mount the Shopsmith headstocks. My horizontal Shopsmith drilling, tapping and milling machine uses a cut down steel total shop table.
No Shopsmith internal headstock parts will fit the total shop
