Your coil should run at about 303.6kHz.
The secondary inductance is 11.95mH
The secondary effective capacitance is 23.0 pF
You should tap the primary at 3.7 to 4 turns. (like just under 4)

The fan shroud is a neat idea!

Glad the contact with the MOT was "survived" =:-O

Try tapping the primary at just under 4 turns and see if you get any
output.  There should be a few sharp edges on the shroud that should have
at least a little arcing of them if not nice streamers.  If not, write back
with any details of what happened and we will dig deeper...

Cheers,
