This restoration is on a 1910s Model "B" electric breast drill made by the Temco Electric Motor Company. The tool was sent to me by a viewer who wanted me to bring it back to original condition.
I was immediately intrigued as this is the oldest electric drill I have ever had my hands on.

This drill was designed and produced before the trigger switch drill was brought to market so the switch design was incredibly interesting and complicated. The drill also had a ball bearing around the drill chuck shaft, which would have been quite expensive at the time. Temco also offered a grinding wheel attachment for sharpening drill bits as well as a valve grinding attachment. The drill is so old that it was made before electrical wall outlets were common and standardized, therefore the tool would have originally been plugged into a light socket.

Restoring this drill was quite a lot of work as all the bushing needed to be remade, aluminum castings repaired, gears brazed, and cast iron parts japanned.

This was a really fun project and I'll be sad to send it out of the shop, but happy when it gets back in the hands of the viewer who sent it.
