Hi all,

Not sure if I should just put all these projects into one thread, so merge if you need to Lee.

Anyway, this video is a project in earning "wife points" :)

Also I've left the"warts" in e.g. the double sided tape not sticking.....

erm, scuse my ignorance , but if the outside 'Y' arm and the bobbin are both spinning at the same speed then how does the thread get wound on ? ... *blush*

A good question, I'll ask the "operator" in a sec.......I just made them the same as the original...no idea how the thing works....gulp

OK the verdict is that the nylon line, which runs in the groove I cut into the larger diameter disc is tensioned using a peg, which then retards the bobbin in relation to the Y arms. So the whole assembly spins at a rate that twists the fleece, but the bobbin is slower and the spun thread then get laid around it.

Hope that makes sense.....
