The mystery is solved about the Spin-Fix tool. It's definitely a skein winder/swift. My friend Cathy, aka Boom, found it on a german blog. Just scroll down a bit and there's a picture of it how it should look. All I have to do is unscrew the square middle pieces and turn one 180 degrees - then it will hold the arms out in a cross. This is great - not only do I have a fun little swift but it's very compact. It's going to live at the beach - compact swift for a compact cottage. Thank you Boom!
