Hi Jean,
Are you still going to use a hyd prop? If so, where is the governor drive
and how do you supply and return the oil? You need a sleeve on the opposite
side of the 3-1 gearset to supply the oil and return with hook type piston
ring seals. How will you account for thermal expansion differences between
the SS tube and the carbon tube? The hub bearing could probably be supplied
by a 1/4 inch tube external supply and then a 1/2 inch return connected to
ports between both seals and the bearings if you use an electric prop. If
still using the hyd prop, how much oil flow do you need which will give the
tubing size needed.
