Welcome to the forum Les, I’m sure someone will be along to give you a hand.
that router is in the vintage class of tools...If anyone has a model A, cat. 680 Millers Falls router, could you tell me the size-thread for the collet nut? I have aquired one, motor works fine but the collet and nut are missing. Perhaps someone might know of a current day manufacturer with a compatible nut. Thanks in advance!
