A rather unusual feature was the drive from electric motor to countershaft; the motor pulley was a two-step V type which drove, via a V belt, onto a very large-diameter, narrow, flat pulley. This apparently senseless idea (of a V belt working on a flat pulley) actually performs perfectly well - but it has been known for disbelieving owners of used lathes to convert the motor pulley to a narrow flat type - and suffer dreadful slip as a result.
