What is the taper ratio of the flywheel end of the e-shaft?

My rough measurement appears to be about a 1:5 ratio.

As near as near as I can measure it the large diameter
is about 1.693" or about 43 mm it is probably 43 mm.

The small diameter is about 1.469" or about 37.310
Length is about 1.250"

The best bet is set up a lathe and make a few
females out of aluminum bar stock and try them.

Paint the inside of the taper with blue Dykem
and tap the aluminum parts on. You will see
problems right away.

It is extremely important to get the taper right.
