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 (http://www.deltamachinery.com). 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
