off I had these giant 2 foot fiberglass shells we’re going to be scaling those
shells we’re going to be scaling those
shells we’re going to be scaling those shells down so it’s a little bit more
shells down so it’s a little bit more
shells down so it’s a little bit more manageable but the same principles can

feet long to make it so I could fit the
feet long to make it so I could fit the pieces into my car this one is cut down
pieces into my car this one is cut down
pieces into my car this one is cut down to 1/4 of that size so it’s 4 feet long
to 1/4 of that size so it’s 4 feet long
to 1/4 of that size so it’s 4 feet long and 2 feet wide this is the 2 inch foam
and 2 feet wide this is the 2 inch foam
and 2 feet wide this is the 2 inch foam and it’s what we’re going to be using
and it’s what we’re going to be using
and it’s what we’re going to be using today these shells are tall and almost
today these shells are tall and almost
today these shells are tall and almost spherical in shape so we’re gonna cut
spherical in shape so we’re gonna cut
spherical in shape so we’re gonna cut out 6 of the squares from the foam glue
out 6 of the squares from the foam glue
out 6 of the squares from the foam glue them all together and that will give us
them all together and that will give us
them all together and that will give us a 1 foot cube
a 1 foot cube
a 1 foot cube [Music]
[Music]
[Music] we have our marks measured out and now
we have our marks measured out and now
we have our marks measured out and now we’re gonna use this handheld miter saw
we’re gonna use this handheld miter saw
we’re gonna use this handheld miter saw to cut out the individual squares
we have our six squares cut out and
we have our six squares cut out and we’re ready to glue them together but
we’re ready to glue them together but
we’re ready to glue them together but this foam is made from polystyrene which
this foam is made from polystyrene which
this foam is made from polystyrene which can be dissolved by the solvents and a
can be dissolved by the solvents and a
can be dissolved by the solvents and a lot of types of glue so what we’re going
lot of types of glue so what we’re going
lot of types of glue so what we’re going to use is this expanding foam in a can
to use is this expanding foam in a can
to use is this expanding foam in a can it glues the foam together really well
it glues the foam together really well
it glues the foam together really well and it doesn’t dissolve it shake your

apply a thin layer of the foam and press
apply a thin layer of the foam and press her next piece down on to it I like to
her next piece down on to it I like to
her next piece down on to it I like to use bamboo skewers stuck in through the
use bamboo skewers stuck in through the
use bamboo skewers stuck in through the sides to keep it from sliding sideways

blew all six pieces together using
blew all six pieces together using skewers on each layer and place a weight
skewers on each layer and place a weight
skewers on each layer and place a weight on top to help minimize the expansion of
on top to help minimize the expansion of
on top to help minimize the expansion of the foam always wear gloves when we’re
the foam always wear gloves when we’re
the foam always wear gloves when we’re using this expanding foam because it’s
using this expanding foam because it’s
using this expanding foam because it’s really sticky and very annoying to have
really sticky and very annoying to have
really sticky and very annoying to have on your skin also make sure you’re
on your skin also make sure you’re
on your skin also make sure you’re wearing clothing it you’re okay with
wearing clothing it you’re okay with
wearing clothing it you’re okay with getting dirty depending on the
getting dirty depending on the
getting dirty depending on the temperature and humidity the foam will

temperature and humidity the foam will take an hour or two to dry completely
take an hour or two to dry completely
take an hour or two to dry completely once it has it will be rigid and
once it has it will be rigid and
once it has it will be rigid and inflexible our expanding foam is dry so

inflexible our expanding foam is dry so it’s pull out the bamboo skewers
it’s pull out the bamboo skewers
it’s pull out the bamboo skewers sometimes they’re glued to the foam on
sometimes they’re glued to the foam on
sometimes they’re glued to the foam on the inside so it’s good to have a pair
the inside so it’s good to have a pair
the inside so it’s good to have a pair of pliers to help with grip that one
of pliers to help with grip that one
of pliers to help with grip that one doesn’t want to come out we’ll probably
doesn’t want to come out we’ll probably
doesn’t want to come out we’ll probably run into that skewer while we’re trying
run into that skewer while we’re trying
run into that skewer while we’re trying to carve the foam it’ll be a little bit
to carve the foam it’ll be a little bit
to carve the foam it’ll be a little bit annoying but we just cut it off as we
annoying but we just cut it off as we
annoying but we just cut it off as we get to it our foam is now ready to go so
get to it our foam is now ready to go so
get to it our foam is now ready to go so let’s start marking out the design from
let’s start marking out the design from
let’s start marking out the design from the top down these shells are fairly
the top down these shells are fairly
the top down these shells are fairly round so I’m going to draw an ellipse on
round so I’m going to draw an ellipse on
round so I’m going to draw an ellipse on the top of the foam and then carve off
the top of the foam and then carve off
the top of the foam and then carve off all the sides until we have a cylinder
I’m going to be using the same handheld
I’m going to be using the same handheld miter saw that I use to divide the
miter saw that I use to divide the
miter saw that I use to divide the squares up it’s narrow and it’s straight
squares up it’s narrow and it’s straight
squares up it’s narrow and it’s straight and it does a really good job of cutting
and it does a really good job of cutting
and it does a really good job of cutting through the foam quickly
through the foam quickly
through the foam quickly [Music]
after the quick cut with the sauce and
after the quick cut with the sauce and very rough sandpaper will help you take
very rough sandpaper will help you take
very rough sandpaper will help you take down the ridges left in the foam now we
down the ridges left in the foam now we
down the ridges left in the foam now we have our cylinder let’s start adding
have our cylinder let’s start adding
have our cylinder let’s start adding some basic details these shells have a
some basic details these shells have a
some basic details these shells have a ridge around the middle with a little
ridge around the middle with a little
ridge around the middle with a little bit of a curve in it so I’m going to
bit of a curve in it so I’m going to
bit of a curve in it so I’m going to draw that in first I’m just adding a
draw that in first I’m just adding a
draw that in first I’m just adding a mark where the front and the back are so
mark where the front and the back are so
mark where the front and the back are so I know where the curve should begin and
I know where the curve should begin and
I know where the curve should begin and end this line I’m gonna draw that goes
end this line I’m gonna draw that goes
end this line I’m gonna draw that goes all the way around will be the highest
all the way around will be the highest
all the way around will be the highest point that I want the ridge this second
point that I want the ridge this second
point that I want the ridge this second line will be the lowest point of the
line will be the lowest point of the
line will be the lowest point of the ridge
you can see that I’ve now drawn this
you can see that I’ve now drawn this band going all the way around I’m now
band going all the way around I’m now
band going all the way around I’m now going to use a thin razor blade to cut
going to use a thin razor blade to cut
going to use a thin razor blade to cut about an inch in all the way around the
about an inch in all the way around the
about an inch in all the way around the band so that when I cut down from the
band so that when I cut down from the
band so that when I cut down from the top the piece will break off there’s a
top the piece will break off there’s a
top the piece will break off there’s a bamboo skewer that wouldn’t come out of
bamboo skewer that wouldn’t come out of
bamboo skewer that wouldn’t come out of the foam I just sliced right through it
the foam I just sliced right through it
the foam I just sliced right through it with the saw
now we do the same thing on the other
now we do the same thing on the other side sounds like bamboo is okay guys
side sounds like bamboo is okay guys
side sounds like bamboo is okay guys update we can now start to see the very
update we can now start to see the very
update we can now start to see the very basic shape of the shell start to emerge
basic shape of the shell start to emerge
basic shape of the shell start to emerge and it’s time to take down the excess
and it’s time to take down the excess
and it’s time to take down the excess and give it that nice dome shape you can
and give it that nice dome shape you can
and give it that nice dome shape you can use a soft for taking down the large
use a soft for taking down the large
use a soft for taking down the large pieces of if you want but one of my
pieces of if you want but one of my
pieces of if you want but one of my favorite tools for shaping this foam is
favorite tools for shaping this foam is
favorite tools for shaping this foam is some 36 grit sandpaper it’s very rough
some 36 grit sandpaper it’s very rough
some 36 grit sandpaper it’s very rough and takes down the edges quickly
okay we’ve got a dome for the top of
okay we’ve got a dome for the top of Michelle coming along quite nicely now
Michelle coming along quite nicely now
Michelle coming along quite nicely now let’s move on to the bottom of the shell
let’s move on to the bottom of the shell
let’s move on to the bottom of the shell on the bottom these shells do have
on the bottom these shells do have
on the bottom these shells do have something of a neck at the front which
something of a neck at the front which
something of a neck at the front which looks a little bit like a doughnut so
looks a little bit like a doughnut so
looks a little bit like a doughnut so the first thing we’re gonna do is carve
the first thing we’re gonna do is carve
the first thing we’re gonna do is carve out a place for that first we’ll draw a
out a place for that first we’ll draw a
out a place for that first we’ll draw a line to keep it centered
now let’s take our razor blade and do
now let’s take our razor blade and do the same thing we did with the Ridge
the same thing we did with the Ridge
the same thing we did with the Ridge going all the way around I’ll cut a
going all the way around I’ll cut a
going all the way around I’ll cut a round of the neck and then sawed down
round of the neck and then sawed down
round of the neck and then sawed down pieces of the foam to that point
now that we’ve got the neck blocked in
now that we’ve got the neck blocked in let’s go back to using the saw in the
let’s go back to using the saw in the
let’s go back to using the saw in the same paper to take off more foam and
same paper to take off more foam and
same paper to take off more foam and block in the bottom shape of the shell
we’ve got our basic shape carved in now
we’ve got our basic shape carved in now let’s open up the neck hole and sand
let’s open up the neck hole and sand
let’s open up the neck hole and sand down and refine all of our edges to open
down and refine all of our edges to open
down and refine all of our edges to open up the neck hole you could use sandpaper
up the neck hole you could use sandpaper
up the neck hole you could use sandpaper or razor blades if you’re really patient
or razor blades if you’re really patient
or razor blades if you’re really patient but I’m going to use a rotary tool to
but I’m going to use a rotary tool to
but I’m going to use a rotary tool to speed things up a bit
yeah Foam everywhere just it gets
yeah Foam everywhere just it gets everywhere now that we’ve taken down the
everywhere now that we’ve taken down the
everywhere now that we’ve taken down the ridges let’s go over the whole shell
ridges let’s go over the whole shell
ridges let’s go over the whole shell with a high grit sanding sponge to

with a high grit sanding sponge to smooth it all out we smooth down the
smooth it all out we smooth down the
smooth it all out we smooth down the shell and now the only thing left to do
shell and now the only thing left to do
shell and now the only thing left to do is put in the four indentations that are
is put in the four indentations that are
is put in the four indentations that are the turtles leg holes
our shell is carved and smoothed down
our shell is carved and smoothed down now all that’s left is to carve in the
now all that’s left is to carve in the
now all that’s left is to carve in the shell ridge pattern on the top and the
shell ridge pattern on the top and the
shell ridge pattern on the top and the belly lines on the bottom after I draw
belly lines on the bottom after I draw
belly lines on the bottom after I draw in those lines I’m going to carve them
in those lines I’m going to carve them
in those lines I’m going to carve them in using sandpaper wrapped around a pen

there you have the paint is dry and the
there you have the paint is dry and the only thing left before our shell is
only thing left before our shell is
only thing left before our shell is ready to mold is to use a little bit of
ready to mold is to use a little bit of
ready to mold is to use a little bit of spackle to fill in any gaps or cracks or
spackle to fill in any gaps or cracks or
