It doesn`t really matter where you start providing you have all the holes correctly marked out. Start of using a small pilot drill and let the drill do the cutting ie don`t press hard to go thru` the material your cutting.
After you have drilled your pilot holes, and thay all line up, use a larger drill if need be, and go up in several sizes untill you get to the desired size.
I would suggest you use masking tape to mark the holes and this should stop the drill from "wandering" all over the place when you start of.
Good luck and don`t use the hammer action!!!!!!! |
