BollAero18 End float?

[Marsh]

Hi All, Thanks to Chris Boll and Ron Chernich I am making two BollAero18s.
Can you please tell me how much end float I should go for on the crankshaft?

I aim for 0.005 to 0.010" on my diesels. I almost always mount my prop drivers on tapers on the crankshafts. Sometime I push the prop driver too far up the taper and lose my end float, which requires me to take the driver off and face a little off of it or crankcase journal.
