Oh hey, I'm Tim Carter, AskTheBuilder.com. I'm getting ready to drill some holes to install
0:12
some anchor bolts for a garden gate. And the original jam that was here got rotted out
0:19
so we need to replace it. And you know what, I want you to watch what I'm doing and see if you
0:25
can figure out why I'm doing what I'm doing. And then at the end of the video, we'll see
0:31
if you guessed right. Let's get to work. Okay, what do you think of this Bosch Bulldog cordless rotohammer drill
1:12
Isn't it amazing? There's a reason why I use it, because I've used these kind of tools in Bosch for my entire career
1:19
Love them. So why do you think I drilled this hole at these weird angles Do you have any clue So is the back of the hole wider you know deep inside this concrete block pier is it wider than the
1:32
front? You bet it is. Here's what I did. I drilled it so it's like a wedge, so that in
1:38
the back it's wider than the front, and here's why. We're going to blow this hole out of all
1:43
the dust. I'm going to squirt in there some special concrete epoxy and push the bolt in
1:49
and make sure the epoxy oozes out. And when that epoxy hardens behind, you know, deep inside the wall
1:55
the epoxy is going to be wider than the front. So when I put tension, when I start to crank down on this bolt 48 hours from now
2:04
that bolt's not going to be able to pull out or the epoxy plug
2:07
That's why you don't want to drill just a single straight hole when you do an epoxy repair because you'll just pull that entire plug out
