If you are cutting hard brass then you can make cutters from silver steel (drill rod)...
Thanks Keith, there's some great ideas there, and the free-standing motor could be one of the three DC scooter ones I have already.

I think the spindle would have to be inclined slightly to cut the thread at the correct angle?? These angles would change from item to item depending on the pitch.

How on earth would you make a cutter?? I guess you would start with the (for instance) 55 degree triangle profile at the end, then mill alongways to create individual teeth?? How many 'teeth'?? Apart from the U3 lathe I have the milling attachment (with fine feed), and the indexing / dividing attachment, so I guess there is no excuse!
