Here's one for you. As you can see it's not hard at all if you take your time. Also, if you chamfer the hole with a drill bit it makes it easier to start the tap straight. If you lived nearby I go over and do it for you and make sure it's done right. You can't really mess it up> Well .....you could mess it up if you go too fast and break the tap in the hole but there are ways to remove a broken tap as well, done it numerous times.
