I'm trying to remove the key from the x-axis lead screw. The hand wheel came right off but I can't seem to get the key out. First I tried prying up gently with a small screw driver. The I took an awl and stuck it in the end of the slot and tried prying up. Then I put a screw driver against the end and tapped gently with a hammer. Then I took a drift punch and tapped a little harder. ALL I succeeded in doing was mashing the key stock a little bit. How the heck do you get that darn key out?
