so i decided to do the free mod first make my own stubby cone
here is a few pics
hope this works out prop is still gong to be ordered soon
start with a nice billet chunk
machine the o-ring/ grease chamber
turn it around start on the angles
my stubby cone was 42mm long so final angle is 55deg in the front
basically you start at 30deg and work your way up to 55 this will give you a few steps but you get a file and polish those away then fine sandpaper until smooth finish
here is finished product before the bolts holes are machined
now with bolt holes machined
the rear
installed
with reduction nozzle on
hope this works will let you guys know tomorrow
