Making RC steam boat



A remote-controlled, aluminum boat that needs gas and steam to be moved is our new construction with the number 0095. It is commonly known that there are more efficient ways to move this remote-controlled, small boat like the electrical motors as well as the internal combustion engine. However, this time we chose this way as we found it a constructive challenge and a good learning around the matter of moving something using steam.

Initially, we made a boiler from stainless steel 316, in which you can enter some water. Also, by making a Verner for propane, which passes from the middle of the boiler, the water heats and is turned into steam. After making the boiler, we had a pressure test at 100 bars in order to make sure that it is suitable and tolerant to lower pressures that will be produced from the pressured steam. Next step, we modified a vane motor for air, on which we put a propel that causes the movement that is produced in the water. All the prementioned pieces are placed on an aluminium boat that we created.

We also, used an aluminium sheet metal due to its low weight and its flexibility to be formed. Our aluminium boat is 110cm long and 35cm wide. Additionally, we placed the propane tank at the front side and the boiler at the back side of the boat. Further, we placed a tube in the shape of a spring to increase the steam production in the boiler as well as to achieve a greater surface of water heating and to avoid the liquefaction of the steam when it moves towards the motor. 

Regarding the handling of the boat, we put a receiver that receives the demands coming from an RC controller in order to enable us to give orders from a distance. Thus, using one of the levers of the controller we turn the boat to the right and left through a flap that is located behind the motor which is moved by a servo motor 25kg. In addition to this, to move the motor, we activate a 12v steam electro-valve placed on the controller and when it is activated the steam moves with pressure from the boiler towards the motor in order to achieve the spinning of the propel and in extent the move of the boat, too.

In the last step, we painted our boat to the colours that we usually paint our motorized constructions like orange, white and red. Even though, we applied a lot of changes and trials at the end we managed to have a good performance of movement and function of our construction. The total weight of our boat is quite a lot as it weighs 25kg. We must admit that we are proud of our creation and very pleased that we managed to move our boat using steam. Who knows?! Maybe in the future, we will make more vehicles that will be moved by steam.

Making Garden Spiral Hole Drill Planter



In our effort to make this week’s project 0094, we took the decision to make an easy project but very functionable, easy to use and useful. We made a tool that is placed in every drill and enables us to drill holes on the ground for planting various plants. Nowadays, many people plant flowers and various plants either for creating a garden or for having their own biological production of fruits and vegetables. Therefore, this drill hack makes planting a faster, more restful and pleasing procedure.

First of all, we started doing this project by taking a metallic, circular rod, on which we created a thread using sheet metal. This thread compared to the threads used on a screw has a lot of depth and there is a lot of space between them. Particularly, the thread that we have created is based on the thread discovered by Archimedes. This is a thread used for the transfer of materials like soil sand, water and other things. 

On the outer layer of this thread we put a tube that on the outside has a conical shape of three degrees. His top part is thicker and gets thinner as it gets closer to the edge of the auger. This tube is pressured by a spring and covers all the thread besides the initial spirals. In this way, when the spiral auger spins and screws, the tube gets lower and is wedged in the ground as a result the tube stops spinning and the soil sand comes to the top with the spiral auger through the tube. 

The functional outcome of this project is not to need exerting resistance against the screwing of the screw in order to make our tool restful for the user. Also, the tube in the conical shape holds the walls of the hole that we drill constantly to prevent the refilling of the soil sand before the planting. Thus, we just made a simple but an extreme project as well as an amazing drill hack!

Making a velocity stacks for cafe racer



A relatively easy construction is what we have made for this week compared to the rest that we have uploaded on our channel. In favour of a friend of us we made two velocity staks. Velocity staks or air horn are constructions that have a particular shape and are placed at the air intake of a machine. Even if people usually think that the placement of these constructions is only done to make something look better from the outside it has also a great functional importance. Additionally, they help in smooth air absorption of greater quantities of air when it is needed preventing the  air's turbulence causing a greater and smoother functionality of the motor. 

The material used is aluminium to achieve a light weight. A relatively simple construction and project that any inexperienced person in this field can do to develop his abilities in lathe. Thus, our 0098 project is ready making our cafè racer better and prettier!

Making a solenoid boxer engine


An electromagnetic machine is this week's new construction by the Make it extreme team. 

To start with, we took the coils from a car's old starters that are capable of attracting a metallic piece inside them as soon as they get activated by an electric source. Therefore, we applied two metallic pistons on a gear rack, one in each edge. In this way, when one of the coils gets activated the rack moves  on the right and when the other one gets activated then the rack moves on the left. A switch helps this reciprocating movement to become constant and with a great speed. 

To transmit this movement to an axis with the same, constant speed  we used two one-way bearings. When the rack is moved right and left the axis which transmits the movement is always moved clockwise. This is an original way of movement transmission and that is what makes our machine so special. By adding a fly wheel on the axis of movement transmission we manage the constant and smooth rate of our machine. 

To conclude, even though this machine has been made experimentally, we are very pleased by its performance compared to our similar construction, called coil engine with the number 0045. We are certain that we are going to make more in the future as they attract a great constructive interest.

Making MASSIVE electric vise



One of the most useful tools in the field of constructions is the vise. The make it extreme has made a heavy type of vise with the number 0063 that we use on a daily basis.

The vise that we created this time is electrical compared to our previous one which  was manual.

Our new tool opens and closes by pressing a pedal and its move derives from an actuator 24v capable of exerting power of 6000N. This power is interpreted to  the vice's jaws equal as 600kg or 1322,75 lbs. 

This vise provides you the benefit to have handsfree when you put a piece on it and it doesn't require body action during the tightening. Even if it can be used for multiple uses, it is more useful in holding pieces of wood during their agglutination as it makes the whole procedure faster, more relaxing and using greater strength in tightening. Also, it is bigger than those sold in the market as it is 90cm in size and its jaws are 27cm wide. Additionally, it can keep a piece between its two jaws of 40cm size.

The actuator opens up to 20cm so  we created a mechanism that the user can use the back jaws quickly and 20cm more backwards in order to place a piece bigger than 20cm. Therefore, we completed the first step by accomplishing an opening from 0-20cm and at the second step 20-40cm. Moreover, the source of electrification of the motor is a transformer of 240v ac inpout and 24v dc outpout.

This vise is considered very big in size as for its construction 150kg iron was used. This model of vise might have been easier to be hydraulic. We might make a hydraulic vise in the future. To conclude, we are very proud and pleased of adding and this vise in our workshop.
