Manual do Mundo was challenged by Rexona<br>to test the efficiency of this deodorant. But since we are exaggerated, and we like that you learn something<br>with our videos, we decided to sweat it and teach you how to do a racing go-kart. I'll start doing a basic car, one that is simple and easy<br>to make at home.
For that, you need ball bearings,<br>like these. You can buy them at <br>auto parts stores. This is a ball bearing for trucks,<br>but this one is expensive.
We paid around R$25,00<br>in each bearing. You can go to a car repair shop, because sometimes they throw it out or<br>can sell them for a cheap price. Now this is something important:<br>they don't have to be equal.
But the back ball bearings have to be equals;<br>the same goes to the ones in the front. That is, you need matching ball<br>bearings to the back and two equals to the front. Another ironwork that you need<br>is a screw with bolts.
This screw is 10 cm long X 1 cm thick. I'm also using 4 washers and you will <br>understand why in a moment. You also need two axis, to attach the ball bearings on the edges.
The ideal is for the axis to be thicker <br>than the bearing hole. In this case, this axis is 4 cm X 4 cm<br>and 65 cm long. And, last but not least, you need a board.
I'm using this board, which is <br>20 cm wide X 1,20 m long. The ideal is to use good wood. <br>I'm using Cedar, which is this one.
It is stronger than Pine,<br>which is a more common wood, and it is the one used on<br>Manual do Mundo's panel. But it is kind of soft. Let's do this!
Let's start by the most boring part, which<br>is fitting the bearing in the axis. For this I am going to wear the wood<br>down using rough sandpaper. But you can use a utility knife,<br>a saw or an emery.
Then you just hammer the bearings<br>in the places you wore the wood down. Now, I need to attach these <br>axes on the board. The back is easy.
I mark 5 cm at the end of board, drill, glue and screw. On the front is a little bit more complicated. Mark 15 cm at the end of the wood, place a support wood <br>for more resistance.
and then drill a hole on the kart<br>and on the axis. Now screw everything. <br>But between the axis and the kart, you need to place two washers.
And below the screw head and the bolts too. If we were making just a simple<br>go-kart, this would be already enough. But we want a<br>racing kart!
Let's start placing a base for the seat, using two boards 20 cm X 26 cm long. On the first board, screw above the base using to supports so you don't<br>force the back axis. The second one you <br>just glue and screw.
On the front, I will place a third board, a Pine one, 30 cm X 60 cm. <br>This is where the hand support will be. The base is ready, and the cockpit<br>we are making with these two boards.
They are 30 cm wide X 40 cm long,<br> with this cut. I am attaching these boards<br>on the seat sides and then I'll place as a back support a Pine board Pinus 42 cm wide X 30 cm long If we want to make this kart run, we have to install breaks on this thing. For that, let's use wood pieces, about 5 cm wide X<br>38 cm long.
First, round off the kart base. Then, wear down the wood to make it<br>better to hold on to, drill a hole in the middle of it,<br>drill a hole on the side of the kart and attach with screws on both sides<br>of the seat. Finally, it's time to make this look<br>like a real racing go-kart.
For that, I am attaching two airfoils. Airfoils are those pieces that work like<br>an airplane wing, but on the other way around. Instead of making the car take off,<br>they make the car stick to the ground.
The airfoil is 20 cm X 65 cm,<br>the same width of the axes. On the front, use glue with hot glue<br>and a 15 cm support. On the back also use the hot glue, but use a bigger support, 45 cm.
It is almost looking good. It is time to turn it into a Lotus. Let's hit the track!
Pit stop. . .
Are you alive? More or less. .
. At least you smell good! It does not leave you!
