I don't know if this is the right forum for this question or not but will give it a shot. I have to drill a 1/2 inch hole 10 inches deep into wood outside my home to seat a piece of metal bar. The hole must be perfectly straight so that the metal bar will be level. Although my drill has a built in bubble level I was wondering if there is an attachment for my Ryobi drill that would allow me to control the drill much like a drill press platform? I've3 looked online for such a product without success. If not if anyone has any advice for me I'd appreciate it. I'm only going to get one shot at drilling this hole. Thanks for the help.
