porsche fan tool ?, undoing the pulley nut

[hot66]

for those of you with porsche fans, have you bought the 'special' porsche tool to prevent the fan from turning when undoing the fan pulley nut?

if not have you made yor own or used another method?

I have not looked at my fan assy yet because its in a box somewhere, so I can't tell yet wether the above tool is needed or not.

Yes, a special tool is needed (at least on my fan pulley) and not hard to make with a little welding.
