- Good day all, Uncle Knackers here.
I'm now at that stage in my renovation where I'm installing
molding, architrave, trim, or casing depending
on which part of the world you live in.
Now this job is very simple to do
and can be completed in only a few steps.
And the great thing about my method is that
you hardly have to use a tape measure.
So it becomes a little bit less complicated.
Let's get cracking.
Now first thing you need to do is to mark
the margins on your window frame.
Now the margin is also known as the quirk,
which is the gap from the edge of your trim
to the inside of your window frame.
And normally that gap is about
an eighth of an inch or three millimeters.
So the first thing you need to do
is to mark that margin or quirk.
To make the window easy to mark out I've set up
my T square or set square to have a margin
of three millimeters or one eight of an inch.
Now all I need to do is to set this on the window
and run that around the perimeter.
So grab your square and place it on the window frame
like that, get your pencil on the underside
of that bit just there,
and it's right around we go.
And that will give you a nice even quirk.
With those quirks now marked, you can also see
how we have a nice sharp corner
to measure our architrave from.
Now the first thing that I do is that I measure
the entire width of the window.
And that's from the outside of the frame to the outside
of the frame, which in this case is 1250 millimeters.
Now I'm doing this video in metric,
because trying to convert from metric to imperial
can vary a little sometimes so I'll leave
a link to a converter in the description box below.
Just in case you need to convert your figures.
Alrighty so we've measured the entire width of that window.
Now all you need to do is to add two widths
of your architrave and do the same
for the height of your window as well.
Okay we now have the top and the bottom.
And they are cut roughly to length.
We also have both sides cut roughly to length.
And they've all got square ends on them at this stage.
Now the next thing you need to do is grab
the one you're going to be using for the bottom architrave,
and cut a 45 degree end on it.
So you need to set your saw up to 45 degrees.
And simply slide the base across until
it locks in on that 45 degree angle.
If you haven't got a miter saw you can use
a miter box and cut it with a hand saw.
So while that's in place, get your architrave
and with the back edge put it up hard against the fence.
Grab some safety gear and cut.
With that 45 degree angle now cut,
take this piece over to the window and mark it.
Now carefully with the short point on your miter
line that up where these two lines intersect.
Just like that, hold it in place,
and with a sharp pencil mark where these two lines intersect
onto that inside corner just like that.
Once you've marked that take it to the saw
and cut a 45 degree angle.
So again that's the way I want the 45 degree angle to be cut
so the back of the architrave or the trim
is hard up against that fence.
There's the line that we want to target,
and whenever I do this I always cut slightly longer first,
and then slide the piece over
until the blade hits that line.
Just like this.
Get rid of that piece.
And now to slide the architrave across.
And bang, there we go.
Now take this piece over to the window, and nail it on.
Now when nailing the trim to the window
you need to get one nail into the window frame itself,
and on into the stud or the trimmer beneath the window.
So in this case, we got one just there, can you see It?
And on either side of this frame there's also a stud.
So find out where that stud is so you know where
on the outside of the architrave you need to nail.
So place the architrave in the right spot.
Both short points are on those intersecting lines,
and then nail.
That's pretty good there.
Come down here.
Nail that.
And then along the window following
that black line that we marked on previously.
Okay so that bottom is now nailed.
The next thing you need to do is put the two sides on.
So those two pieces that we previously cut,
we'll get a 45 degree angle on those first,
bring them over place them on the window frame
and then mark where they hit the
intersecting cross at the top.
And again just place a mark where
these two pencil lines intersect.
And do the same thing for the other side.
And now off to the saw to cut
45 degree angles on both of those boards.
No before I nail this piece on I like to run
a bit of PVA glue along the joint.
Like that for the glue, beautiful.
Now place the architrave in place,
making sure the corners match up nicely.
Like that.
Okay the bottom's sitting nicely,
and the top looks good we're good to go.
So one nail into the window frame, and one into the stud.
Now work your way up the window frame,
sticking to that black line or
the pencil line that you marked earlier.
Now with my nails, I'm using a 50 millimeter nail,
which is about two inches.
Some guys like chop and changed.
And they'll put a smaller now into the window frame
and a longer nail into the stud.
Cause when you got through the stud,
you've gotta go through full thickness of architrave
plus plus the board of dry wall, and then into the stud.
But that's a bit of mucking around
and you've gotta have two different sets of nails.
I just use 50's and that way everything holds beautifully.
Okay, other side.
Alright that's all done, now the last step
is just to cut that top architrave.
And to do that just simply measure
from the outside of one to the outside of the other one.
And I am 1349,
1349 millimeters.
I'll cut that and I'll come back.
Alright, let's give it a go.
Yeah.
Look at that, look at that.
That is beautiful, what we need to do
is to run some glue on both of those ends and then nail it.
And there it is, all done.
How easy was that?
Great tip Knackers.
Well I hope you enjoyed and found that video useful,
and as per usual a big thumbs up is greatly appreciated.

Alrighty, I think it's time for a cup of tea.
So till next time, I'm out of here, cheers.
