I picked this up today from a marketplace ad. Rockwell 503 HD 3 x 24 Belt Sander. Runs great, needs a new cord, and a thorough cleaning. I haven't opened up the gear case yet, and still need to check the oil!! Belt tension lever and tracking mechanism seem to be okay, platen is a little rough, but it has potential!! Hard to find these in good condition, and with the proper dust bag and fitting!!!
