My ancient Sioux has a rocker arm attachment with movable pin position to accommadate most rockers, a set up to radius worn lifter bottoms, also has the micrometer set up to grind flat head Ford valves to length. Just think, people used to REPAIR, now they just replace. For race engines only we have an even older Black and Decker dry grinder that leaves a perfect mirror finish but has to have a 10 minute cool down after each step so a three angle valve job takes almost a week. My Tobin-Arp grinder has the exact same stone speed from a brand new stone to a worn out one but along with brake shoe arching, riveting shoe and clutch facing, stick welding,---all just gather dust with resto/street rods having LS and Ford Modular engines with automatics and disc brakes. Need to load Jerry's trailer up on his next trip.
