You've jarred my memory, what little is left. I do remember now Dad also
using lard and possibly kerosene as there was usually a can of it in the

AND THANKS for the mention of aluminum as I had tried threading that
unsuccessfully a few years ago and resorted to drilled hole and bolt. The
drill wasn't bery happy either but I did git-er-dun.

Lard or kerosene for aluminum, cutting oil for steel.
