i am now the proud owner of a Lionel widget.

It means i can at last get the rear wheels off the car for cleaning.
My question :- Is copper ease grease on the splines and spinners a suitable material?
What is the required torque?
I have read the various threads on the topic of how tight which seems to advocate 3 or 4 smacks with the hammer after a hand tightening.
If this is done will the torque required to then loosen the spinner be a good indication.
The lionel widget does allow the extension bar (scafffold tube ) to just lean on the spanner. ie no shock loads
Has anyone asked the manufacturer what their recommendation is for torque settings?
