I use an australian article written by one of our propeller
makers.(Bishton)
the aim is for 600psi clamping force or thereabouts.
5/16"dia bolts try 5 - 8 lb ft
3/8"dia bolts try 10 - 13 lb ft
1/2"dia bolts try 18 - 25 lb ft.
yes we use belleville washers.
correctly installed the wooden prop is capable of outlasting the
aircraft.
