Point taken, I looked a couple of hours ago and only found one - a 66mm long cutter with 1/4" shank.

I'm sorry if in my last few posts I've appeared to think I know more than I do about this. I do value your advice as you clearly have a lot more experience than I have. This discussion has made me think more about what went wrong than I would have otherwise. Still I think there was more to it than the tool extension, since had the router not stalled then I think it would have been fine - it was cutting fine before it stalled.
