They were in a handbook of mechanical design, the hydraulic section, and
applied to hydraulic oil only.

This post was in reference to the Clem Engine so the working fluid will of
course be Mazola Corn Oil. The engine supposedly ran at 300 degrees. Mine
will be similar.

Hopefully Mazola at 300 Degrees is similar in viscosity to hydraulic oil.
Only a couple of hydraulic experts replied but I had no hope of a Mazola
expert. This whole machine is a shot in the dark but a couple of starting
points won't hurt.
I need all the help I can get. Thanks
