I have a Rockwell/Delta 17-600 variable speed drill press with a variable speed pulley problem. According to delta it is from the early 1960's and the part is no longer available. The problem is the variable width pulley mounted on the motor has a nasty wobble which results in big vibrations. This is the older style, without a spring. The fixed part of the pulley (where the wobble is) is mounted to a splined shaft that mounts on the motor shaft. The pulley is pinned on to the splined shaft, and evidently it wasn't true when it was pinned; hence the wobble (axial play). Does anybody know where I might get a good used part, or has anybody had any luck with machining off some of the splines and installing a bushing??? I have tried Ace tool repair and Joe at Plaza machines, with no luck.
Thanks in advance for any help or advice. Chris
