Feather Weight tension assembly spring
While working on a Morse Lightweight tension assemble that came undone unexpectedly, I was looking at all my other machines (singers) and noticed that one of my (3) featherweights did not have a tension spring in the assembly. I wondered if it was necessary because the last time I sewed with it (couple of years) it worked just fine.
2nd question: Does anyone have a schematic for the Morse tension assembly? I couldn't find anything on the internet.
