  • Old 20" Delta /Rockwell Drillpress

    Need some help, just picked up an old 20" Delta Rockwell single spindle and weighs about 200 - 300 pounds with a 1 1/2 hp 220 v motor with 8 speed pully. I need to know what type of tapered spindle it has. It swollows my mt 2s

    MT3 maybe?

    Go here and see if you can find your model.

      My 2HP Variable speed Rockwell is an MT3.

        Check the tech support section of Delta Machinery. If they don't have the user's manual on-line, call 'em up and they may be able to fax you a copy. I just finished this process for a Delta bandsaw that pre-dates the Rockwell years (last patent dated 1941). They couldn't match the model number but the manual and parts list they sent (for free) looks right. Good luck!

          I bought one new in 1967.
          Has a #3 MT spindle and a two speed, six step pully on the head.
          You changed speeds from direct to planetary reduction "granny" with a half turn of a straight blade screw driver.
          Also has a crank elevator table.

          I put a DC drive on it, back then, still there.

          It will pull a 2" pipe tap, or a 6-32.

          Good luck with it. Should last you a while.

            Thanks for all your help, I visited the Rockwell site with no luck. The Model #70-6X0 cannot be found, but the serial #1635*** I think showes it to be a 1942 vintage. This is a bench model and I am missing the swing table for it.

              CCWKen reminded me.
              The old wood working machines (OWWM) site that he linked has a 1938 Delta Catalog on line.

              You may be able to find your machines immediate predecessor model number there.

              I see Black and Decker has bought the Delta badge now.
              Good luck Ag
