This wouldn't be an issue except the treads are down inside a recess 3.75 " deep. The holes need to be tapped .220 deep and the hole can only be .325 deep. so I'm not too confident in a bottoming pulley tap. Never tried to EDM anything this extended, any tricks to success? I have 24 holes to thread.
