You know I don't know if we got
a clear enough background last time.

What we're doing is for
an undergraduate Honors Program seminar.

We are over the course of a semester
building a full scale replica of

the rose hut.

Now people have done this before but
what's special about ours is we're keeping

this accurate as possible meaning
we're using only the tools and

techniques that the road would have use
which means instead of using a chainsaw to

cut down a tree or
buying a lumber from a from Home Depot.

We're going out there with a broad X.
and an X.

and we're taking down the trees ourselves
because we all know that when thrown out

there to to Walden Pond and
build his own house.

He didn't go to Home Depot and
buy them into lumber.

I mean sure they there were different
methods of building houses back and

then they use smaller pieces of wood but
no throw was a true true conservative.

He used temper framing he went out
there with and found the trees.

He definitely went out there.

He took up what we.

Well we know very little about what
he actually did which is why these

projects interesting Do we
know he borrowed an axe and

we know he went up there and
timber frame this house.

So we're going to try and

do that as close as we can the trees
themselves are the raw material.

You're not dealing with packaged
lumber and it's interesting to

know what I'm doing as I'm giving you how
to presentation on how we're actually

doing the stair gave you the why I'm
the how you start with your tree.

You're making an incision by
alternating horizontal and

then forty five degree angle Stillings.

And the second swing will be about six
to eight inches above the first and

you keep alternating that into the in
nice not about six but about halfway

through the tree a little more so
when you start swinging from the back.

You did make the same kind of not from
the back about three inches or so

above the first notch and at this point
it's really a waiting game you sit

there and you listen to the sounds
that you're going to make and

being someone who's
been able to follow it.

Your military in this manner.

It's really cool because
you just listen and

you wait to hear the cracking of
the the U.S. The fibers inside

the tree until the tree falls at this
point you run the hell out of the way.

Especially when I'm not down a tree.

It actually started it was leaning the
other way from I wanted to tall the right.

It started leaning to the left and so

the people in this I run
toward us run toward us.

So I didn't.

Get killed by a tree.

I didn't that didn't
get injured that sign.

But once you get on the ground
you realize more than ever.

How this really is a raw material and
we need bridge.

We have to turn this into six by six
years or four by four beams which is what

the row would have used and so
would that means cleaning off all the crap

you know getting the branches off of
there getting the bark off of there and

then cleaning off the side which is when
you think about it is a pretty large

amount of material this shows you
the examples between a novice and

a professional at this
the one on the left.

Obviously someone has at its various with
an axe before the one on the right someone

has never picked up an axe in their life.

And you can clearly see the difference and
it'll really helps a lot saving time

because if your strokes are precisely and
you cut through the tree a lot faster.

The one tree went down like fifteen
minutes the other one took over an hour.

Here you can see that once
you get it on the ground.

You've got to clean it up which means
getting the limbs off of it you can use

a saw or an axe for

this and the last legs the better because
you get knots at the base of each limb.

So when you're hitting it with an axe
that's going to cause the X.-Plane to

glance off instead of
trying to cut through.

It's much easier to cut in line with
the fibers in the fibers are all tangled

up inside the knot.

But once you do get it cleaned up you get
the limbs off you get the bark off with

a spade or shovel you get these nice.

What are some likely in logs.

I mean there at least a lot at this point
and it's funny even though when we found

out when we started cleaning these off we
get the bark off of them they're sticky

they're glistening with SAP And so
you pick up these trees and it's almost

as hard to get him off of you as that
ours is the get him off the ground.

And important an important problem that
we had that the road in we had to move

our trees the road when he went out to
all the pond he picked the site for

his house partially based on what
the trees were like around them because he

knew that was what the what the what he's
going to use are going to be the trees

closest to a site.

So we walked out there and said the South
going to be here cut them down and

tell them right there next.

This is a building site after you
get the trees to our location.

We had to figure out how to square them.

There's two methods to do
this you can use this.

But it by driving wedges in at certain
points along the trunk and basically

splitting it down the middle and you can
cut two square people two square pieces

of lumber up out of this or the other
method that we're going to be using more

is just squaring off one side first making
that nice and flat and then from there.

Dropping down two lines and cutting off
the sides and then finally the fourth side

as you can see this is a Dr Crawford swing
in ads and as a tool used to us move off.

One side of the smooth office lumber
it's actually really precise tool

when Square and
we either use an ADS or brought X..

But the first step is there's already
a lot of wood off of this tree of but

you drop a chalk line down straw
the line give it a nice chalk line.

So you know where you're cutting because
you have to at least semi measure at this

point to ensure a little bit of accuracy
but the idea is you have one side

flats you measure out where the second
side is going to be the stand on top.

This is using the broad axe method not
the adding method you stand on top

on your flat side and you swing with
your axe down between your legs.

And you make these nice incisions
that go to the chalk line

as deep as the top line and they're about
six to eight inches apart that way you can

come from behind in the come
up behind after this.

And so that the broad accent chopped
off these nice big chunks so

with the follow pretty easily.

This is the wrong way to
use a broad axe by the way.

If you the whole idea is that you stand
on the left side of the trunk and

you swing taking off with him the right.

You do that because that way if the blade
misses for whatever reason keeps going.

There's a piece of wood between you and

the tree and I have six ditches to prove
that this is the wrong way to do this.

This is the correct way to do this.

Brought X.
in the ads are both self-regulating tools.

They're very very sharp and
what that means is that they know

what they want to do to complete the job
the broad X. itself is sharp and

on the right side of the blade as
you can see here the psychosis.

And it's flat on the other side
which means when you're swinging it.

It's not going to want
to cut into the tree.

It's going to want to cut away
the material to it's right.

And here's the ads.

Again the ads is just like the boxes
used to square the temblor.

But instead it works a lot smoother.

It's a lot slower so actually we've been
using it more to smooth out the sides of

the tenders and once we actually get them
relatively square with the broad axis.

Because when you operate this you're
standing with the what the adds on top of

the log and
you're swinging it down to your foot and

the the general boast back in the day was
that the experience of Adam and could

split is the soul of the suit and half
without touching his foot or the wall.

But here we are removing our trees.

Now we get to move and the next step
to our project is going to be cutting

the joints and measure carefully and we're
going to cut up all the specific joints

and to this is a big beam so
eventually we can fit our cabin together.

Another interesting thing that we have
that we really think about when we started

this was a waste material because you get
a tree of this this big around you're

turning it into this much there's all that
volume of wood that has to go somewhere

and there's a foot in the upper right hand
corner you can see this is just a a huge

pile of waste from just a few logs.

And that piles a pretty quick.

But here's here's our dimensional lumber.

It's not as pretty as the Home Depot
one but we got to make it ourselves and

I think that's pretty pretty cool.

That's all I have received.

Thank you.
