1. Welcome to the class: Hi, everyone. Welcome to the
class. My name is David. I'm an industrial designer,
a university professor. And in this class, I'm
going to teach you how to craft a wooden
bowl on the lathe. This piece you see here
was made out of maple Barl It's a unique kind of wood that you can
easily find online, or you can purchase one from
your local Woodcraft store. This class is an
intermediate level, which means it is
expected for you to have knowledge and previous
experience on woodworking, using safety equipment such
as protective eyewear and gloves and other tools like
drills, saws, and sanders. However, if you don't
have any experience with these tools and machines,
don't let that stop you. I invite you to watch
this class and get inspiration for your
next crafting project. So without any further ado, put on the safety glasses, and let's begin our class. I'll see you in the next lesson.
2. Preparing the wood: Okay, great. Welcome back. So to begin our
project, we'll start by examining the piece of wood
we have on our workbench. For instance, here,
you can see this really weird looking piece that appears to be some
kind of foam or fungus, but it's actually maple burrow. These types of woods are amazing for wood turning and ideal since the grain they have is naturally highlighted in the
turning process. You can see the surface
of this piece looks actually very bizarre,
almost alien like. And if you look at it closely, it actually looks
like if you were visiting an alien
planet of some sort. So to begin with,
let's start by having an idea of the proportions
and working area we have. Since the surface is
completely regular, it's a good idea to
draw a circle and encompass the area that is
useful for us to work with. Now with our measurements
and ideas in mind, we can cut the piece to a reasonable size before
installing it too late. If you happen to have a
piece of pearl like this, you can cut the excess on a
pencil and then send the edge if you want to have
a more precise feel of the proper dimensions
of your piece. Now, since this is an
intermediate class, it is expected for you to have previous knowledge
on woodworking and how to properly use these tools and the safety
instructions for each machine. When you're happy
with the result, it's sand you prepare
a wooden piece and install it to the late
in the next lesson.
3. Installing the burl to the lathe: Now it's time to install the
maple barrel to the lathe. Each lathe has its own
configuration and design. However, they follow
the same principle. Firmly attach a wooden
piece from edge to edge. In this case, the lathe
I'll be using has this metal adapter that
needs to be screwed to the wooden piece and then
screwed to the lathe through the circular mechanism
you see in the center. To install this
adapter to the burl, I use eight screws in total. Do the same with your lathe
and just remember to make thin perforations on the wood with a very thin bor or drill. These holes will serve as guide for the screws
and will avoid any misalignment and fracture of the wood and screws themselves
when installing them. When you're done, you can
play your wood in the lathe, test it spin, and we're ready to start working with the
outer part of the bowl.
4. Working the outer side of the bowl: Great. With our bul
installed to the lathe, we can now start working
with the outer part. Before we begin, however, I want to remind you
of the importance of wearing your protective gear. Don't forget this is crucial to start working with machines. Now turn the lathe and set
it to 800 to 1,000 RPM. Then with your cutter, slowly
start removing material. Since this piece is
extremely regular, you don't want to
go hard at first. You want to know
where the cutter is going to hit with the wood. So I suggest to start
by gently getting close to the wood and then
start removing material. Also, start on the side of
the lower part of the ball. This way, you have more control if you need to get
away from the wood. When you feel you're removing a material on the lower side, you can work your way
through the center. Start removing material from the center outwards
as you can see. When you level the
entire surface of the center and sides, you can move on freely to
make it even more even. Stop the late whenever you need to check how you're going. Don't worry if you stop
it many times at first. As long as you're sure that's the dimensions you're
looking for, it's fine. When you're done with
the bottom part, move on to the sides. This is going to be done exactly the same way as you did
with the bottom part. Stone the edges and move your way through the
rest of the surface. At this point, we've removed enough material with a cutter. We can now send the pearl piece, starting with 100 grit sandpaper and moving all the way
through the fin as you can. I ended up sending this piece up to 2000 grit
sandpaper, for instance. And A cool trick someone thought me once
is to use the shaving remains of the wood and use them as if it were a final sandpaper. And it actually
works really nice. It leaves the surface
much smoother and shiner than with just
the sand papers. When you're done, we need to
turn the ball the other way around and install it on the late to work
with the inner part. To do this, we need to glue a
piece of wood or plywood on the base and let it dry for at least 3 hours before
we can continue. In the next lesson,
we'll see how to remove material from the
inner side of the ball.
5. Working the inner side of the bowl: Welcome back. So as
you can see here, the pole is glued to a
plywood from behind. This will allow us to install
a ball from behind and work away with interior without having to press the
pole on both sides. To start working your
way in the inside, first draw a guideline that shows how large the
bowl is supposed to be. Then with your cutter, start removing material right on that guideline, as
you can see here. When you've removed enough
material from the guideline, you can start removing
material from the center of the pole outwards. Making this will ensure
you always remove the right amount of material every time you pass your cutter. M. When you're happy with the
depth of the ball, start removing the edges
with a round cutter. Then soften the sides of
the bowl to ensure it has a continuous feel on the outside and on
the inside as well. When you're done, we can continue to sound the
inner part of the ball in the next lesson. O.
6. Sanding the inner side of the bowl: Now that the bowl has
been completely turned on the inside and we're
happy with the result, we can start sanding with some sandpapers and
the help of the lathe. To ensure a really
nice polished surface once we apply oil in the end, we need to leave the surface
as smooth as possible. For that, we need to
send the ball with all the sandpaper
grid as possible. For this project, we
need to use grids 100, 120, 18220, 320, 400, 600, 1,000, 1,200, 1,500, 1,000 802,000 sandpaper. And we need to send
them in that order. So turn the lathe and sand
against the movement. At first, you might not
feel the papers hot, but the finer the paper
you're working with, the hotter it gets since it's making more
friction with the wood. To avoid any burns, I suggest you put on some
gloves while sanding the bowl. Once you finish with all the grids and papers, use the same leftovers of the bowl to give it
a nice last sanding. This will leave
your wooden piece smooth and ready for the oil. We'll be using some Danish oil. This oil has some resin and
feels sticky when applied. So I suggest you use
some latex gloves and a brush to apply it
evenly on the surface. When you're happy
with it, we can continue to cut and remove the ball from the lathe and finish the outer part
in the next lesson.
7. Removing the bowl from the lathe: Removing the ball from the
lathe is quite simple, and you can actually
do it in two ways. The first one is using
the lathe itself to cut the ball from the wood
that holds it in place. You can use your cutter
and gently start removing material until
the ball comes loosen. If you plan on doing
this, I suggest you remove material from
behind the cut so you have enough space
between the ball and the wooden plank to not harm the ball with the cutter,
as you can see here. Also, when you're
getting close to separating the ball
from the lathe, you might want to hold the ball with one hand and the
cutter with the other. So when it comes loose, you can grab it and doesn't
go flying and get stemised. Another way to
remove it is to use a handsaw and carefully separate the ball from
the wooden plank. In the next lesson, we'll send the back part of the ball where it was glued to
the wooden plank.
8. Sanding the outer side of the bowl: Now that we've removed
the bol from the lathe, we can send the backside where it was glued
to the wooden plank, and we can start by using an electrical sender to lat the surface as flat as possible. Here you can see I'm using
the sander vertically since I needed it to be in that
position for another project. But you can adjust the sander horizontally and it will be
much easier to work that way. We can sand the
outer part by hand again using our
sand papers until the surface is
completely flat and without any leftovers
from the other wood. When you're happy with
that, we can continue to apply some oil and finish
our bowl in the next lesson.
9. Finishing the bowl: The last step to finish our bowl is to apply some Danish oil. Danish oil is an
amazing product that will not only highlight the
natural beauty of the wood, but also protect the
surface from moisture. When applying Danish oil, make sure to use some
latex gloves and a brush, as well as to place a piece
of cardboard below the bowl to prevent any oil from staining your furniture or workbench. Applied three coats
of oil and let it dry for about
a day to the sun. When you finish, your
bowl should have a lovely appearance and is ready to use or as an amazing gift. In the next lesson,
we'll talk about the final project for this
class. See you there.
10. Final project: To Great. So in this class, you've learned how to
make a wooden bowl using traditional wood
turning techniques. We went from preparing
our wooden pieces and installing
them to the lathe, removing material on the
inside and outside of the bowl and finishing our project with a
nice Danish oil. As you can see, this
project is very simple to make and it's
actually quite relaxing. You don't need a lot
of woodworking tools, but do need to have precautions
when using the machines, especially the cutters and saws. There's no limit in the type of wood you can use
for this project. Maple bores are beautiful, and since they're very hard, turning them becomes easy with the help of the lathe and
well sharpened cutters. Now it's time for you to
build your own wooden bolt. Get creative in the process and explore different
heights and shapes. When you finish, make sure
to upload your project in the project section so other
students can see it as well. Thank you so much for
watching this class. I hope you have enjoyed
it, and I'll see you in the next one.
Have a great day.
