A long time. And it would be very hard work. Is the wall solid brick? Did it say that anywhere in the thread? If it did, I missed it.
Moreover, unless you have a big, heavy, powerful, expensive electric drill, it will be inadequate for drilling through a solid brick wall. The $10 drills won't do it.
But it really doesn't matter. I wasn't recommending that anyone use a manual drill. I was simply responding to the statement "Don't most people have a drill?" I'm sure that Char meant "Don't most people have an *electric* drill?" and I was just pointing out that the word "electric" was omitted (probably inadvertently).
