Just wanted to let everyone know that it is not impossible to thread the crank for the safety shaft after the crank has been nitrated. Mike Hyers recommended a local machine shop which caters to industry, (not an automotive machine shop). I told them that the crank had been nitrated but he was not concerned by that as he would not be using a conventional tap. I do recommend that the crank be threaded prior to nitrating as it can be done cheaper and easier but it is not impossible to thread after nitrating.
