A while back I had gotten away from using the OEM control horns because I always had a really hard time drilling straight through for the top and bottom pieces to line up with the screws without making it look like swiss cheese. Ive since started to use the Dubro HD control horns which only use a single bolt; which is a bit easier, but the use of a drill press would probably help to get a perfect result. I have no plan on getting a press, so was wondering if you guys had any useful tips for others to get proper alignment when drilling holes for the screws. Any tips would be appreciated.

Thanks
