Default Re: Singer sewing machine sticky pedal

Hi
update on the sewing machine which is a Singer 185K, handbook dated 1958. I got my husband an ex-BBC engineer with an electronics degree but no experience of sewing machines, to come in on this, and took photos of the dis-assembly of the controller. We thoroughly cleaned the linkages, and re-lubed with white grease (a tiny amount!), cleaned the brass contact pads with P1000 paper and polished up the large contacts with ethanol. The capacitor buzzed out ok but he does have a spare if needed. All those drawers in the garage come in handy at times. We reassembled and tried it out without fabric or thread and it still runs but although I think it's better it's still a bit keen! We didn't attempt ot clean the carbon discs as we could do the rest as these actions would still be reversible.
I had a go at uploading the photos but I can add others if you need more details! All the photos were numbered in the order taken but that format has disappeared.
