Following on from the chain thread.
Is there anything wrong with filing off the hooks on worn chain rings rather than replacing them? Obviously the teeth get a bit smaller but it should be okay for at least one go.
My question would be, could you do a decent job in less time than it would take to go to work and earn the price of a chainring? In theory, it could be remachined but it would be weaker (less tooth behind it each time) and near impossible to get it accurate enough by hand.
Nothing wrong with it as a stop gap measure. I did consider it myself for a nanosecond, but the faff was just not worth dropping down to a steel Deore middle ring for £8.
Probably right about the faff factor

I do filling, on chainsets reaching the end of there lives, gives you a couple more weeks out of them.

But you forget it not just the chainring he'll need to replace, it's also need a chain and cassette...and it literally takes minutes to remove a chainring and file the hooks off.
