woodsmith, good advice. The reason I double drill is to make the hole concentric, not straight. If I have a problem with the drill walking, I will EM it. Otherwise, just double drill to remove the 'bell mouth' that often occurs when drilling.
BTW, I notice a new thread that appeared to be a reply to this thread, it had the same contents, so I removed it. If you intended a new thread, lemme know and I'll gladly restore it. (Mayhaps this is a good candidate for someone to post in the Tech section??)
