Ask Iris, I'm pretty sure my American made marbles are somewhere on the shop floor in amongst the leaves and trash that blows in under the door....
I'm figuring on spending some more time there tomorrow - I should clean it.... Maybe if I get too frustrated with that 319 needle clamp.... Anybody know how to put a Singer 319 needle clamp back together? So far I know what doesn't work. Holding your mouth right doesn't score that's for sure. If I ever get it back together I will be sure of NEVER taking it apart ever ever ever again. I've got an hour and a half in on it so far. I actually got it to ALL go on backwards once... I know that isn't right. I'm at a stand still on that machine until that gets fixed. Maybe some net sleuthing will come up with something.
