    drilling holes

    The only really easy way to do it is to let your helper drill them. It just has to be done, so get to it. A good drill and sharp drill bits make life easier. I've seen a laser advertized that goes in the first hole and sends a beam of light to the next joist and so on thru all the joists, making it easier to line them up. Can't find one yet, but when I do, I will own one.
    Happy drilling !!!

    Sharp bit, powerful motor

    2" hole at least as you need to get two tubes or more thru the holes.

    The B&D TimberWolf on high speed with a razor sharp bit is the way to go.

    That Stabila hole alignment laser is very handy for that. I'll send mine up for you to try if you'd like.
