Randy,

The sizes are so close, drilling and muscle aren't necessary. Only the proper cutting fluid is.

9/16" is only about .011" bigger than 14mm, and 20tpi is only .02mm more than 1.25. You'll be surprised how little metal is removed.

hello,

when re-threading a set of french-threaded cranks to accept 9/16" pedals, do you drill the old threads out using the recommended drill size, or do you just muscle the tap in there and go for it?

thanks,
