Ok. I surrender, and will go back to my 12-24 Regina 7 speed instead of the new Sachs. That said, I've learned I need to square up my dropouts after spreading the forks to avoid stress on the axle. But the question I still have is this.....is there a source of 10mm x 26 tpi locknuts of a thickness less than 7 mm? I understand that the existing locknuts are typical of this vintage hub, but my issues would be solved w a skinnier locknut. Do they exist? Does anyone know where they can be purchased? Thanks.
