Gasoline engine aluminium boat

An especially distinctive structure has been created this time by our team approaching it from different views both structural and functional. Besides our structural interest of creating it and the development of our knowledge and experience, our main aim was our entertainment while making it. We decided to make our own small, aluminum boat that will be able to carry only an individual in the sea providing him the sensation that he is surfing by just using a gasoline powered engine. 

Firstly, we started our structure by cutting aluminum iron plates into pieces conglutinating them air tightly. In this point, we should say that our preference for the aluminum material was made for its great endurance and its light weight. Therefore, we had the opportunity to experience how to conglutinate aluminum using a mig welder. After connecting the aluminum pieces, we gave them the shape of a small boat keeping its upper surface closed and flat. Then, we had to place the engine at the back of the boat and put a propeller at its end. Next, using the lathe we made all the essential pieces in order to place the axis and the propeller on it and the particular pieces were connected to the engine of our boat. 
We chose an engine that was taken from an old tree-cutting company and it has been repaired before used. Our aim was to connect the engine to our structure without causing any damage in order to be able to be restored to its former function used at the tree-cutting company. Also, we chose the particular engine for various reasons of which the basic one was its small size. Additionally, we regulated the evaporation of the engine to be made on a high point of the boat in order to prevent water going in while evaporating as well as we created air inlets to oxygenate the engine sufficiently. Moreover, we created an output where we put the rope for starting the machine. For our own safety, we made a metallic frame around the propeller. Also, we put a safety switch that is placed in the hand and it deactivates the machine when the user leaves the boat. Our boat weighs about 45kg and it is capable of displacing about 180kg meaning to sink it completely 135kg should be placed on it. At the point, where the axis sticks out of the boat, we prevented the insertion of the water using water seals. Just in case, we placed a water pump inside our boat in order to get the water out if it gets in. 

We must admit that we are very satisfied from our boat’s sailing and the way that it deals with the water. However, we felt very disappointed about the engine used as after numerous attempts and after using multiple propellers, we came into conclusion that we could not get the desirable speed and the power of the engine to use our boat as a surfboard, too.
What we can say for sure, though is that using a more powerful engine and if our structure was lighter, the outcome would be successful. Also, it would be surely more preferable if our engine was water-cooled to avoid high temperatures. Whatismore, for keeping it lighter in size, it would be recommendable to use carbon fiber that is very light in weight and has high water-resistance. In addition, instead of using a propeller, a jet mechanism would be better obtaining a better performance. In conclusion, we have notified many potentials of improving our structure and increasing its functionality and we can certainly say that we will attempt to create such a structure again considering the above potentials of improvement as due to our current budget the particular changes were not feasible to be implemented. 

Nevertheless, completing this structure, we gained more experiences and we had fun every single moment creating it as well as enjoying the sea of our country.

It's possible to use the angle grinder as a chainsaw

Carrying on our tradition of our video sequel for angle grinders, this fourth time we transformed our grinder into another useful machine, a chain saw. Our primary aim for this transformation was experimental while the usefulness of the particular machine came second in our priorities. 

We first did this experiment for multiple reasons such as to see if the angle grinder could really work as a chain saw, whether the angle grinder is burdened, if it gets warm and if it can be used as a last resort in case of an emergency. 

Therefore, our work starts making a metallic plate, on which the angle grinder is adapted and stabilized when necessary. On this metallic plate, we placed a metallic rail taken from an arboricultural factory as well as the chain and the gear of the particular machine. The chain that we placed on the metallic plate is revolved on a high speed without derailing its way supported by the gear that revolves the angle grinder at the particular time. This metallic rail has the potential to move towards and backwards as a result to enable us to set how tight or loose we want our chain to be. 

Then, we made a protective cover around the chain close to the parts that we place our hands in order to reduce any danger. Thus, without any special difficulty the angle grinder 4 is a fact!!!! 

After completing it and testing it, we got amazed by its performance as an electrical chain saw. Although, we consider that this was a transformation of a high risk. Also, we must say that using a bigger angle grinder, the performance will be dramatically increased. However, the advantage of this transformation is that none of the components is modified as a result they can be easily returned unchanged to their primary position, where they were placed at the chainsaw. 

To sum up, this particular transformation costs very little money and it can work in many different cases having great results. Additionally, it is much lighter than the common gasoline powered chainsaws, much less noisy with a small angle grinder and this is obvious when it is used for many hours as its temperature increases.

Making a hoverboard from Junk

Glad to say that's the 42nd structure by make it extreme! For this structure we were inspired from many videos uploaded on youtube where people use hover boards for entertainment. 

Our aim was to make a hoverboard using the parts of an old gym piece of equipment as well as other recycled and reused materials. We took a 300w motor and the electronic parts out of the gym piece of equipment so the motor would be able to perform correctly!

The next stage was to make an axle, using the lathe, where we put two old tires from a crashed four wheeler. Then we placed the electronic parts the motor and the wheels on a metal frame and the hoverboard started getting shape.  

We used a belt to connect the wheels to the motor and that's how we achieved movement using electricity. Here came the issue!! We had to use a 12v battery to a 240v structure! This issue was solved using an inverter, which was the only piece we had to buy, once we didn't own one. Then we placed a metal sheet on the board in order to be able to stand on.

It's dimensions are 110cm x 32cm.  

We initially believed that it would be easy to keep our balance without the use of a gyroscope sensor but when tried, that was extremely difficult. So we 've placed a small wheel behind the wheels in the center and the balance was achieved!!

Using the hoverboard, we noted another serious disadvantage which was the missing of breaks!

It is undoubtedly one of the most extreme hoverboards ever made!!

Make it Extreme's Workbench

The idea of our next video and structure came up after trying to create our working place, where we make our structures and our video clips. Therefore, we made our workbench. 

Even though, it sounds simple to be made, it is not; as this working bench has some specialties compared to the most common ones. Making this working bench, our primary aim was to make it going up and down adjusting it to the proper level that we need to work in order to enable our body and don’t injure our back by taking the wrong posture while working. Also, we aimed to make it more functional, comfortable and relaxing as it is possible. 

The lowest level that we wanted to make it was as high as it is the ground and the highest at the 75cm as this level is the most ergonomic according to the bibliography. The reason that we wanted the nonentity in height was that in case of making a big structure in our working place to be able to have a lot of space to work and not having a long working bench taking the most of our space.
Also, the particular bench enables us to lift heavy objects and work on them at the best height.  To achieve the nonentity in height, we created a cement place below the surface of the ground of our working place in order to be able to put mechanisms like the motor and other stuff in it.  

Therefore, before placing the ground of the working place, we had already dug a place where we put a wooden mold and filled it up with concrete. Then, we made the floor and the only thing that was missing, was our structure. Thus, we made two bases, the one at the bottom which is motionless and the one on the top which moves supported by a motor as well as it is elevated at the height of our desire. Both these two metallic bases are connected with two metallic scissors that are moved on rails supported by the bearing and the more they get widely open the bench gets lower while when they come together the bench elevates. On these scissors, we connected a screw which is revolved by a jack of 240v that was modified. While the screw is revolving, it screws the scissor towards the motor as a result we have some motion.  While screwing, our working bench is elevating however while unscrewing, the bench is declining. On the mechanism that encourages the upward and downward motion of our structure, we welded a whole surface of work that is 118cm x 221cm in size. 

This surface of work was created using sheet metal of 3mm thickness. Furthermore, we preferred a metallic surface as most of our projects were made of metal. Finally, our working bench has a total height 120cm, of which the 45cm are placed below the ground.

Metal Melting Furnace

Another essential structure for the ‘make it extreme’ team is an oven for melting metallic objects and creating new ones. Therefore, we decided to make this oven in order to reclaim the useless metallic objects and create brand new structures in molds for the creation of random structures for various uses. 

To start with, we made cyclical, metallic wreaths. After using sheet metal layering on them, we managed to make 2 cylinders, from which the one is 10cm thick and it consists the cap and the other one is 65cm height and it is the body of our oven. Then, we closed the one side of each cylinder and we made a stoppered, cylindrical-shaped oven. Next, we put a metallic plate on the bottom of our oven in order to place a special molding pot. On the top, we made a hole to pass through the items that we need to melt. In addition, we can also check the state of our oven at the particular time through this hole. To keep our oven warm, we dressed it with mineral wool, which was dressed with ceramic fiber that is a material that endures in very high temperatures. Also, we placed a thermometer on the outer surface of the oven to be acknowledged of the internal temperature of our structure.

Finally, we made an entrance at the bottom of the one side of the oven to place the burner that we manufactured in the previous video shared on our site. By just using a cylindrical gas we managed to get the temperature that we wanted in the internal surface of our oven. Regarding movement issues, we have also the solution as we placed wheels to be easy to move.
