Background:
I purchased this saw off CL for $250 in 2020. The previous owner got the saw from an older woodworker who was selling his tools. The machine also has an identification number for the U.S. Bureau of Mines, a Federal agency which was dissolved 1996. Assuming the Feds bought it new in 67' that makes me at least the tools 4th owner.

Machine Info:
This 1967 Unisaw is powered by a 1.5HP Delta Rockwell motor. Overall the saw was in very good condition with only surface rust and normal wear for being 53 years old. The art deco badge was missing from the dust door. The fences fine adjustment knob is bent. It had no motor cover but did come with the fence, dust door, a miter gauge, and T slots.

This saw is a beast and the centerpiece of my workshop.

Treatment:
The conservation of the saw was straight forward as I prefer to retain original paint and patina if enough of it remains. The Unisaw was first completely disassembled for inspection and each part individually cleaned, waxed, or applied a dry lubricant in the case of moving parts. The arbor was also taken apart and had the bearings replaced with new Japanese ones. The motor spun freely and without problems, so it was only cleaned and dusted out. The three belts were also replaced by a new matched set. The on and off switch sometimes got stuck in the on position as it was full of dust, so it was replaced by a new one with a large off paddle for safety reasons. A new DELTA dust badge was made from aluminum flashing, sharpie, and pop rivets. The cabinet was sealed and a floor installed for better dust control. A custom rolling stand with leveling feet was also made so the surface of the machine is flush with the primary workbench. I purchased and installed a SharkGuard an aftermarket splitter that can attach to the existing mounts for increased safety. I have plans to finish building a dust cover for the motor and for making my own Biesemeyer style fence out of angel iron to replace the OEM fence.
