So does the flat surface of the cone get pressed in past the surface of
the
prop so that the point of contact is inside the hole to give some
stability?
Thanks for clarifying this
Peter
Not sure I understand the question but the top of the cone (It is a concave
cone BTW) where the point of the rod goes should be positioned slightly
above the CG of the prop/spinner, etc.
