Making a differential braking tank transmission



It is, now, obvious that the ‘Make it extreme’ team is keen on making vehicles. Among all the vehicles, the most fascinating ones are the track vehicles like the tank, excavator and other types of vehicles. The difficulty of making them is on the way they turn as to do so, the crawlers have to move in various speeds or even in various directions. However, many systems have been made which enable the track vehicles to turn, thus we chose to make one of these systems. The systems that exist, today, are dual drive, twin transmission or geared steering, clutch braking, differential braking and other. We, on this video, present the making of the differential braking system. The differential system, as it is known, is used by cars and it is the mechanism that resolves the problem of turning these vehicles by defining which wheel will be moved faster or slower during the turning.

Initially, we took a broken differential system from a BMW car and we modified it. We, first, changed the power supply of the movement that occurs with a chain in order to be connected to a machine taken from a motorbike. Then, we made a box, in which all the movable parts are located and need lubrication. Therefore, we made this metallic box to be oil sealed. At the two exit points, where the transmission of the movement will be occurred to the crawlers, we put a disc brake on each accordingly. In this way, we managed to block the movement of the vehicle to any of the two exits and force it to turn to the direction we want.

In conclusion, the reason of making this system is to place it on the track vehicles that we are planning to make in the future. Thus, we paint it in orange which is the colour that all of our motor vehicles are painted. In this point, we have finished an amazing structure holding the number of 0106 with the potential to make future vehicles as its function is excellent.

Making a reverse tilting trike



Although, tilting trikes were made some decades ago, they still seem strange but interesting. Even more and more creators are occupied by making these vehicles as they are in high demand and have more benefits than before. A tilting trike vehicle is one that leans over the side that it turns so it performs better balance while turning and better aerodynamic. 

Our own vehicle is called ‘reverse tilting trike’ because it has the two wheels on the front and the one at the back instead of the opposite like a common trike. The machine moves the back wheel which also leans while the front ones lean. The front wheels were taken from a car so that there are some drawbacks regarding the fact of taking this kind of turns as they do not have the suitable shape for this type of vehicle.

However, we used the particular kind as it was cheaper and easier to be found and used as well  it was efficient for our own presentation. Firstly, we used a 200cc motor taken by an old scooter. Even though, the vehicle seems relatively common from the outside, its driving behavior differs as it offers an unusual experience and a very good sense. Additionally, the mechanism that defines the tilting of the two wheels on the front is relatively, very simple. When the framework of the machine leans on the right side the wheels lean on the right side as well as all the parts move at the same time, too. The springs that can’t be moved simultaneously, they are moved on a seesaw, which is moved at the centre of the framework. This gives the potential to the springs to work from their initial position, which is in every tilt point, where the vehicle is located.

Finally, we painted the vehicle in the colours that we always paint the ‘make it extreme’ vehicles and these are orange, white, red and black. The outcome of this project is amazing and its driving behaviour is impressive so we remained satisfied by its performance. Our vehicle with construction number 0105 holds one of our three most favourite vehicles places in our collection; the other two are the monotrack and the monowheel.

Making a tube bender die



Besides the machine, essential for bending a tube is the dies that are used by it. These dies are responsible for the homogeneous and accurate bending of a metallic tube.

The different sizes of the dices enable us to bend different kinds of tubes in thickness. A common way of making them is with the use of a tool that is used in lathe and it is called "internal spherical turning tool."

As we didn't make such a tool, we decided to show a different way. First, we modified the piece adjusting it to the right size and then we placed it on the dividing head. The size of the tube that we were going to bend was 42mm therefore we should remove a 21mm hemisphere from our piece by perimeter of our cylindrical piece. Therefore, we regulated our fly cutter when it rotates to shape a 42mm circle. We also, regulated it at the centre of the piece horizontally and vertically. While the fly cutter was spinning, we were moving 2mm in the piece and using the division head we were creating a complete rotation of the piece. Repeating the same procedure we inserted 21mm in the piece creating the perfect dice for our machine.

Finally, as we completed it, we used it for bending a tube for our next project reaching an unbelievably good result.

Making a Wood Chipper



The wood chippers are constructions that are more and more in demand because they are very useful for various reasons. The wood chippers are machines that cut the branches and tree boles into small pieces. If you are keen on treating the trees and the gardens well, this causes the gathering of branches that are cut down. However, using a wood chipper the branches will be cut down into very small pieces therefore they will take up less space and their recycling will be easier too. These small pieces can be used to become a pellet for wood stoves as well as fertilizer for the soil. There are lots of types of these machines and each one has its pros and cons. 

The machine numbered 0103 is actually a big flywheel that has two blades on it. While a motor is spinning with high speed the flywheel the blades are cutting the big pieces of branches into very small pieces. Behind the blades, there are 4 wings that make air from the blades towards the exit of the machine. In this way, the branches are inserted from the entrance of the machine and after being cut, they are pushed by the feathered wings supported by the air that is created and then they are tossed out of the machine.

Finally, because the machine is for domestic use, it uses an electric motor 4hp for its movement. The performance of the machine is absolutely impressive and we are really satisfied with the outcome.

Making an Electrolysis tank



Electrolysis owns number 102 in our constructions. Electrolysis is the procedure of decomposing a substance supported by electricity. It is used for the export of pure metals as well as for plating. 

First of all, we started making our construction by taking an old, plastic container of 45x45x45cm size. Then, we made a metallic frame with wheels, on which we placed our plastic container. Thus, it can be easily moved to be cleaned. To be able to move the electric cargo, we modified a transformer taken by an old microwave. Therefore, we modified the transformer in order to exit 13v AC and then supported by a bridge, we turned our exit into DC. 

Regarding the cleaning of the metals from the rust, the negative pole is located on the piece while for the plating we do it the other way round. As we filled our tank with water, we put some washing soda in it and then we sank the rusty metals in the liquid. The outcome of it was unbelievable as the rust was vanished completely from the metallic piece.

To sum up, we are very excited with what we created and we are looking forward to trying it for various kinds of plating such as copper plating and nickel plating.
