We said before that you can save a lot of marking out by drilling holes in one piece, and then using those holes to guide the drill when cutting holes in the other piece. If you have to drill holes like this in a number of pieces, and you want them to all be the same, you can save a lot of time and trouble by carefully drilling small holes in a "master", or "template", then using that to guide you when drilling all the rest. You will find that you achieve surprisingly good accuracy if the guiding holes in the template are much smaller than the size of the final hole, and if you use the same small drill to make similar guide holes in each of the other "work" pieces. These small holes will help center a larger drill bit when you drill the holes out to their final size.
