Attaching props

[FindingNemo]

The most basic of questions which I've just realised I've not considered so far. I'm building the Typhoon, with twin scale brass props and stainless steel drive shafts (no threads on these) from Nautilus Drydocks. How do I attach the props to the stainless steel?
Thanks,
Fish out of water..

Update: it seems this is as easy as cutting a thread and using a lock nut. I had thought cutting a thread on stainless steel would need specialised tools but apparently a standard die will suffice.

Drill and tap a 4-40 hole in the side of the hub. Grind a flat to the end of the propeller shaft. Done.

Thanks David. I had thought that a screw and flat wouldn't be enough to resist torque taking the prop off, but good to see I was wrong.

Works every time.
