I just bought a 111w103 machine. I have been looking through older posts, and there is a lot of great information here. It seems this is the best place to find information regarding these machines. I was wondering if it would be beneficial to put a clutched timing gear in my machine to protect it from damage from thread backing up into the bobbin case. I am somewhat new to sewing, but I am mechanically inclined. I want to thank you for your time and help with this. I am at work, so I cant register now. When I get home I will register, as this site has a wealth of information regarding sewing and older machines.
