Question about cleaning old machine
I am cleaning a 500A that I got at a thrift store yesterday (I posted a pic). I seem to have forgotten everything I did when I cleaned up another old machine. I know I need to lube the gears, but is it safe to clean the gears underneath? If so, I would appreciate any advise on what to use to clean them. I have liquid wrench and evaporust from my previous cleaning project. The wheel feels like it sticks or binds on something when I move it. I have removed the bobbin case. I got a lot of great advise last time. Thanks for the help!
