- G'day, Knuckleheads.
Uncle Knackers here
and welcome to video three of my How to Hang a Door series.
Now in today's video,
we'll be looking at cutting the door jambs to length
and then installing the door hinges onto that door jamb.
So without further ado,
let's start cutting those jambs.
♫ Cut up the jamb
♫ Cut the jamb ♫
So how long do we cut our door jamb?
Well, our door jamb, in this case
is going to be sitting up and down on a timber floor.
Now, we want a 5 mil gap from the floor
to the underside of our door.
There's our door.
And that's a 5 mil gap.
There.
Now, our door itself, that's 2340 tall.
Now the gap between the top of our door
and the underside of our door jamb here
is a clearance of 3 millimeters or 1/8 of an inch.
So if we add the 5, the 2340 and the 3 together,
we come up with 2348 millimeters.
And that is how long our door jamb hinge needs to be cut.
Let's do it.
So with the jamb cut,
it's near time to attach it
to the door hinge itself.
Now, this is the top of our door
and this is our top door hinge.
And this is where my method is a bit different
to most other people.
Most people either use a tape measure
or they use a wooden staff with measurements on it.
But what I like to do is remove this leaf from the hinge.
So fold it over.
Give it a little tap.
Get some pointy-nose pliers
and remove the pin.
Just like that.
Take that off.
And we want to put this on the top of our door jamb hinge.
And just remember that the top of that hinge
is 185 millimeters from the top of the door.
And the top of our door jamb is 3 mil further on
from the top of that door.
So the start of our hinge on our door jamb
is going to be 185 millimeters plus 3 millimeters.
So total of 188 millimeters.
So from the top of our door jamb,
we measure down 188 millimeters.
Which is, take my glasses off,
just there.
So that is the top
of our hinge.
So get that leaf that you've taken off the door
and place it onto the jamb
and line that edge there up
with the edge of our door jamb.
Just like that.
That's it.
Now with a sharp pencil mark around it.
Just like that.
And now before,
get your square and your Stanley knife
and just make some cuts on those lines.
Like that.
And then on this one over here.
And like before,
I'm going to use my router to cut that hinge out.
And like before, just using a combination of a chisel.
Like that.
With a Stanley knife
just clean up that rebate.
Get the last little bit out like that.
Now get our leaf
and that fits just beautifully.
Now, we want to insert the screws just like before.
Again, using your thumb as a guide.
Try and get it in the center.
Now put some screws in.
And one more.
Look at that.
That is absolutely beautiful.
Now we take this over to the door.
Now what I do next is I close up those hinges.
On the bottom too.
And then get the jamb.
And place it on top of the door.
And onto that top hinge.
And with it in place,
I'm going to put in
or partially put in
the hinge pin.
Just like that.
And now with that top hinge holding the jamb in place,
you can fold it out
we'll get those leaves from the other two hinges.
Place them on top of the jamb.
Hold the jamb in place
and mark where those hinges are.
That's one.
Here's the next one.
Just like that.
It is that simple.
Now we fold these back over.
And take out that top hinge pin.
Now just gently take the pin out.
And release the jamb.
And with your router,
check out those last two hinge rebates
and then clean up the edges
with your chisel and Stanley knife.
Now go ahead and tap out those pins
for the middle hinge.
And the bottom hinge.
And make sure that these go
on the same spot on the door jamb
as they are on the door.
So this is our middle hinge
and this one here is our bottom hinge.
The reason for that is that sometimes
the hinges aren't machined exactly the same
and they won't match up.
So take them out.
And this is the leaf for our bottom hinge.
Now go over toward our jamb
and screw in these hinge leaves.
Alrighty.
All done.
Now we're ready to cut the length for the other door jamb.
And don't forget to put the hinge pins back in.
Otherwise you just might forget
or you might lose them.
There you go, done.
Now the reason why I like to use this method
for marking my door jambs,
especially with a door that has three hinges
is that it's virtually impossible to make a mistake.
Once that jamb is locked into that top hinge, it can't move.
So by falling the jamb out and then transferring the lines
from these hinges onto that jamb,
you can't go wrong.
There's no misreading a tape
or putting a tape in the wrong spot.
I like it.
So with that step done, you know the drill.
Go to the shed, put on those hinges
and then come back for the next video
which I'll leave a link for in the description box below,
where we will assemble that door jamb.
And as per usual, a big thumbs up is greatly appreciated

Okay, go to the shed.
Good luck.
Until next time, I'm out of here.
Cheers.
