Richard,

Thanks for the tip about Ilex shutter plungers. Will be checking out 
various shutters here.

The engineer in me does not like the idea of using a tapered thread in a 
square hole. The Alphax and Betax shutters require a faire amount of force 
to both cock and fire the shutter. Having the appropriate cable will ensure 
that threads are not eventually stripped through using a contemporary cable 
with a tapered end.

Cheers,
