Tel,
Not knowing quite what you want to achieve, or how you are planning to do
it, this might be a bit of a silly question.
But, could you not use a 120 tooth sprocket, and either gear it 2:1, or fit
it with a simple escapement such that it indexes the rotation of the
sprocket by half a chain-pitch?
The latter could be quite easy and might save you making all those teeth.

That would be too easy Jeff. Actually I had a look & the biggest 1/4" pitch
sprocket my supplier lists is 125t - fair way short of the 240 odd teeth I
need
