I know this does not pertain to the breaking thread issue, but i have had a problem finding a good course for needle supplier. I bought an Alder 204-374 from a policeman in NY, it used to belong to Wiz. I used Campbell Bosworth and they can't get the Schmetz needles 794 system. It will be the middle of next month before my order of #25 needles come in.
Does anyone have different needle suppliers?
