[TowerTalk] RE: substitute for BMW Flex-disc ?

[Jan.E.Holm@telia.se]

     Correct, any will most definitly do. I use one from a Ford Granada
     to rotatde a 80 foot crank up with multiple Yagi´s on it. By the
     way a more correct name for this thing is a Hardy disk, at least
     that´s what I have learnet.

     By the way these things are not expensive at all, you can by them
     new in this country for around $30. For little money they are a BIG
     life saver for rotors.

A Hyundai flex-disk ? ;-)

Seriously speaking I think any flex-disk would do it. The torque a 
flex-disk
has to handle during its normal operation is much greater than on any 
ham
installation. Under my 5 ele 20m Yagi I have one, which was taken out 
from
my mom's Opel Corsa (1.1 l engine) after being used for 10 years in the 
car.
It's functioning perfectly.
