How To Build A Pergola Frame – DIY At Bunnings

October 18, 2019


I’m going to show you how to build a pergola.
I’ve got a few different tools here. I’ve got my concrete and my wheelbarrow for putting
all my posts in the ground. I’ve got my power saws here for cutting and drilling all my
timber. I’ve got my levels and my ladders, so I can get access up nice and high. All
my safety gear, a tape measure, pencils, and hammers. I’ve got an assortment of screws
and bolts here for putting bits and pieces together. I’ve got my post stirrup and my
joy stirrups here. Shovel for digging some holes and for mixing some concrete. Handsaw
and some clamps for holding it all together, whilst we’re setting it up. Also I’ve got
my timber beams, posts, and batons. That’s going to be all the material we’re going to
use to build our pergola. One of the first parts of building a pergola
frame is to get the post into the ground. One of the most common ways of doing that
is using one of these post stirrups. We’re going to dig our hole and I’m going to put
the stirrup down into the ground, and then I’m going to concrete it in into position.
My engineering drawings and my council plans tell me how far apart I have to space these
stirrups, the type of post I’m going to use, and how far in the ground I have to actually
dig it all. So I’ve already got that information given to us from council, with all of our
engineering information on it. I’m just about done now with my hole. I’m just going to quick
measure to make sure that my post is in the center. My hole is dug, the next thing I need
to do is put the stirrup into the ground. I’m using these off cuts of timber here to
hold the stirrup over the hole so I can put my concrete in. But before I put my concrete in, I need to
make sure that I am in the right position. If this is a square, there is a good chance
when your post goes up your post is going to be at a square as well. So you really want
to get a good line in here, make sure the’re in position. I’ve now got some concrete mixed
up in my wheelbarrow. I’m going to fill it up until I get just around the base of that
stirrup, it’s going to be around 50, 60 mil below the top of that stirrup. And then I
check it again to make sure I’m still in line because the concrete will move it around a
fair bit. I’ve got this post stirrup in position now. I’m now going to continue on with the
rest of them, and once they’re all set, I’ll stand my post up. Now that I’m waiting for
the concrete to dry on my post stirrups, I’m now going to cut the wiling plates. The wiling
plates goes up on the space here. This is where my rafters are going to come in from
my pergola. And now I’ve already measured it, I’m now
going to cut it to length and I’m going to use a friend to help me put it up there and
fix it into position. Before I put my wiling plates up onto the fissure, the fissure isn’t
a structural member. So what I need to do is find a way to fix the wiling plate into
the ends of the rafters. I’ve already got my nail in my fissure which tells me where
that is, but once I put my wiling plate over here I’m going to lose that line. So I’ve
got to mark underneath here, I’m going to get right along the fissure and mark it that
way. Okay, I’m now going to get my friend to pass the timber up to me, and she’s going
to climb up and take her end up. Once it’s up there, we’ll then nail it off and then
we’ll put some screws into it. We’ve put a few nails up in here now to hold
this wiling plate into position. That isn’t our final fixing, we’re going to put some
large bugle screws in there now. To do that, I’m going to put a square line underneath,
lining with the mark I’ve already put in there, and then down the face. I’m going to put some
clearance holes through here now, and once I’ve got that in there, I’m going to draw
the large bugle screw through to give me extra strength. I’m going to two in the end of each
rafter that takes me through the fissure and into the rafter itself. I’m now going to go
along the remainder of the wiling plate here and put two screws in the end of each rafter.
Once I’ve done that, I can then continue on with the rest of my pergola. You want to get the bugle screw just to go
below the surface. You don’t want to bury it too far and you certainly don’t want to
leave it high. Just below the surface is how it’s going to work. Now that I’ve done that,
it is nice and secure. I’ve cut a template here, and that sits underneath my gutter.
It follows the same profile. So now that I’ve done that, I can cut the profile cut on the
end of all my rafters, and they’ll fit in there nice and neat. I’ve now positioned my
template on my rafter. I’m going to mark it out. I use my square down the face. So I now
want to come in with my jigsaw. I’ll put it down this space as well so when I exit with
the jigsaw, I’m going to sign line as well. And then with my jigsaw, with the right type
of blade in, I’m going to cut it out. Now that I’ve made my cutout, I’ve now got some
raw timber. I’m going to put some primer paint on that so it takes that open surface. I’m now ready to measure, cut, and install
my rafter according to my plans. This is my post, if you can imagine it standing upright.
My rafters that come through. This is an off cut from my rafter. I need to sit into the
post itself, okay? So my rafter will be sitting down the face of the post. I need to make
a cutout in the side of the post to take that rafter and support it, and support its weight.
I’ve now got this marked out. This cutout post will now take the rafter and support
it in position. When making your cuts with a circular saw, be mindful that you don’t
overcut them. Only take your saw to your line. If you take your circular saw too far down,
you will weaken your post. I’ve finished cutting everything now that I can with the circular
saw. I’m going to use the hand saw just to make those final cuts. My next step is to now measure the distance
between my stirrup and my rafter so I can cut my post to its final length. I’ve now
got my post ready to go in. Once I get it in there and it’s plum I’m going to drill
it and then bolt it. Now that I’ve bolted my first post into place, before I move off,
I’m going to temporary brace this one so that it stays up nice and plum. Now I’m going to
go along and stand the rest of my posts and bolt them into position. I’ve installed my
posts with my cutouts, next on a beam is now in. I’m going to put a few screws in to secure
it, then I’m going to start with my rafters. A quick tip when you’re building a pergola,
put a cleating underneath your outside beams, that way when your rafters sit on them, they’ll
sit nice and flush, stay nice and safe. I’m just about ready to install my rafters.
Before I do that, I’m going to transfer this center mark, and the center mark is the center
of my rafter. I’m going to transfer it around the back of the beam, that way I can put my
pilot holes in for my large bugle screws. Once they’re in, it’ll keep it nice and secure.
Okay. Now we’ve got it sitting up, we’re going to screw it off and we’ll put the next one
in. Along this wiling plate, I’ve got to fix this universal bracket. I can’t put big screws
through, so I need to use this. What it does is it allows me to get a fixing along my flat
surface, along my wiling plate and onto the side of my rafter. I need to nail it in with
a portrait [SP] nail. It’s a hardened nail, it’s not just a standard clout. You need to
put at least four or five nails into each universal bracket. I’m going to have a universal
bracket on either side of my rafter. I’ve set this one up, now what I’ll do is I’ll
go along and put the rest of my brackets in. I’ve now finished putting all my rafters in,
I’ve got all my universal brackets on. Now that I’ve done that, I can take my cleat out,
which we put in earlier for a temporary fix. I’ll unscrew that now and we’ll be all done.
It’s now ready for liquor paint, and that’s how you build a pergola.
