is, most likely, 30 years old. I rebuilt it from the bottom up except for the motor. The bearings just froze up. The motor was fine. All the bearing were "off the shelf" standard bearings. Nothing exotic or special. It didn't need any thing pressed off or on that couldn't be done with a vise and deep socket. It was all pretty easy. The paint job was the hardest part. Give it a try. The worst case is that it ends up in a box and any machine shop can put it back together with an exploded print.
