This is a Singer 221 Featherweight sewing machine that belonged to my Grandma. It was made sometime around September 1947.
This machine has the scrollwork pattern on the end plate.
I replaced the access panel screw on the top of the machine with a thumbscrew to make it easier to oil. Now I can get in there without a screwdriver:
I put a thin layer of Super Lube synthetic grease with PTFE on these gears. For the reset of the mechanism I use Tri-Flow oil.
The original motor was this "Catalog 3-100," rated for only 100–110 volts. I ended up swapping it out for a new Alphasew motor.
The Featherweight motors that have lubrication holes should be greased with petroleum jelly (Vaseline), not oil or any other kind of grease. For $2.59 I bought enough to last several lifetimes. Here I've loaded it into a syringe for easy application:
This machine came with the steel foot controller rather than the bakelite version. These made a brief reappearance to the model line in the late 1940s:
I made a small quilted bag for the controller out of some scrap material:
The bag lets me throw the controller in the case without worrying about scratches:
The case has a lift-out tray with a hole in it for the spool pin:
The oil can clip holds on snugly to a bottle of Tri-Flow oil.
