    DoAll surface Grinder, packing seal on hyd cylinder

    Hi All, I have a 1950's Doall Model D-10 surface grinder and it's been a champ for all the years I've owned it, but it's developed a leak in the table traverse cylinder. Looking at the diagram, the seal is by rope packing. In 30 years in the industry, I've never dealt with packing type seals...

    Welding with plain steel filler?

    Centerless End Play Adjustment

    I've got a Cinci 325-12 that keeps loosening its end play on the grinding wheel. I tightened the set screw on the end of the spindle (and tightened the lock nut), but the play gradually increases anyway. Is anyone familiar with the spindle layout on these machines and the adjustment procedure...
