Acquired sander via a WTB on Craigslist. The sander was in pretty good shape and was last used in a Florida stair manufacturing plant according to the seller. It came with 7 spindles, 4, 3, 2, 1.5, 1, 3/4, 5/8; 3 throat rings and a magnetic starter. It was missing the 1/2, 3/8, and 1/4 inch spindles. According to State Manufacturing, s/n 1094 was made in 1956.

Disassembled machine, stripped and repainted. The worm gear was held in place with 2 allen screws but needed encouragement from a gear puller. The bearings and housings popped apart with a light tap. Cleaned motor bearings and re-greased using glue syringe. Spindle bearing were smooth and remain untouched. Replaced original leather Chicago Rawhide CR13720 motor shaft seal with new style CR6372. Ordered bushing for oscillator connector and motor seal from State Manufacturing; however, the bushing did not fit. The original one was still in pretty good shape so it was reused. Filled gear box with 1 quart 30 wt non-detergent oil.

The spindle rack was made from a glue-up of 2 layers of Baltic Birch plywood and was patterned after the plywood original.

The motor is 1/2 horse, 220, 3 phase, manufactured by Master Electric. It is now run on an Autogen static type phase converter. According to Autogen, it produces full-time 3 wire power and runs the motor at 95% of hp for intermittent duty, (approx. 15 minutes). The Autogen folks, Smith Electric Motorworks / GWM were very helpful. There is a comparison chart for static converters at http://www.gwm4-3phase.com/autogen.html

The top and inserts were blanchard ground by Withers Tool, Die and Manufacturing Company in Atlanta, http://www.witherstool.com They did a very nice job.
