i have a cast iron tube that is about 6 inches long with a id of 4 inches. i need to enlarge the id by about a quater inch . my friend who has been a machinist for fifteen years says that he can do it on his mill in his garage as he does not have a lathe. he says that he can jig it up to make it work without much trouble eventhough the quill travel is only five inches. he is a good friend and all but he is well known for overstating sometimes.i need the final id to be within 1000th of a inch. what do you think?
