This drill owned by my wife’s Uncle Fred. Fred was a farmer and carpenter and built homes for people all over Blount County, Alabama. He died on April 12, 2010 at age of 92. His property had already been well pilfered by relatives and local thieves by the time I was given permission to access the property. The drill was found is his shed in December, 2018.
The drill did not work when plugged in. The chuck was locked up tight. Mud daubers had used it for a home. The contact brushes did not match and were very worn. A wire connector was missing. The outlet plug was just hanging on. And the exterior was a well worn and grimy not to mention the interior.
Having never worked on or restored an electric drill this was going to be a challenge. I knew the brushes must be replaced so before any real work happened I had to find a way to replaced them. Brushes are not expensive but finding an actual replacement part for an obscure 1960 drill was not an option. So I took measurements of the brush housing and placed an order. They were too small and wobbled around inside the housing. Second order was certainly going to be too big by a millimeter or so. Brushes are made of graphite. I assumed I could carefully file them to fit. And it turn out that it was an easy task to modify the original brushes, but time will tell if will last. Internal wiring was worn in a few places and that was repaired using heat shrink wrap.
The chuck is a Jacobs Multi-Craft model MC4K61 made in Hartford, Conn. USA.
