Can't trust those Alfa sewing machines, full of rust, never sew straight in the Winter...

The Haynes manual for them is a little yellow thing from TAB Books, called "How to fettle your entire sewing machine, no, really, you've got an MZ and a bunch of Dafs, how much harder could it be?" As most maintenance is basically cleaning away fluff and only ever oiling with the _lightest_ of spots of oil (also fresh needles and good quality thread), it's really not that scary.

Which I why I have nearly as many half-fettled sewing machine projects in the shed as I do cars. Hmmm....
