Thread jam
My neighbor recently bought a FW 221. It had a major thread jam in and around the bobbin case and the hook assembly. She removed the bottom of the machine and has disassembled the entire hook assembly to get to the last bit of thread. I was not with her when she did this.
She can not get the bobbin case base (or maybe it is the gib or both) back in properly.
I know this is a very vague description of her problem but can you tell me how to help her put this back together correctly - or send me to a website that could help?
We both have FW machine. Should we use ours for a comparison to get the new one back together. Don't know that I am willing to disassemble my machine.
Thanks for your input.
