Jet propane torch for metal melting foundry

This time, our structure is a burner, which will be used in our upcoming video. The particular burner will indicate the temperature that currently exists inside the oven the one that we are going to make in order to be able to melt aluminum and other minerals. Our burner combines the air and the propane to create their proper combination aiming to achieve the perfect combustion. 

To make this burner, we used compounds and metallic pieces of tubes that we use for plumbing. Also, we made two entrances, from which the air is inserted to the one and the propane is inserted to the other while both are met and end up in a tube where if they get flamed they will get burnt. Regulating the air and the propane, we get the ‘perfect’ combustion. At the entrance, where the air is inserted, we used a regulator that controls the flow of the air that we want to provide. While the flow of the propane is controlled by a valve that we placed. 

Additionally, we placed a watch on the flask of propane to get the ideal flow of propane by it. Therefore, lighting up the burner from the front and regulating the mixture of air and propane, we get a very powerful and impressive flame, which can warm the oven that we are making, giving us the best possible outcome!

Belt Grinder

After all the requests that we received from our subscribers inquiring to watch how a belt grinder is made, we decided to make one. Therefore, our new structure with the number 0038 is a fact. 

Firstly, we got an oval-shaped flange of 5mm thickness and this is how we made the base of our machine. Then, we designed and cut the shape of the belt grinder from a metallic plate of 5mm thickness and we welded it vertically on the oval base. 

Choosing a very powerful motor of 2hp and 3000rpm, we adjusted it on our base in 90 degrees with the frame of the belt grinder. On the axis of the motor, we placed an aluminum wheel that we made it on the Lathe having 8cm diameter and it is used to revolve the belt from the sandpaper. We also made three smaller wheels on the lathe that are revolved freely and the belt of 72’’ length revolves by the use of the motor on them. These three, free wheels were made by aluminum and their diameter is 5cm. The two wheels were placed motionless on the frame of our structure so that our belt would revolve and move vertically according to the base of our machine. The third of the wheels was placed on a moveable lever which is moved up and down to regulate the stretching of the belt and to help in its change when it is needed. However, the use of the third wheel is not only limited in keeping the belt stretched but also in regulating its move on the right and on the left so that when a screw is revolved, we will be able to choose how left or right our belt will be declined in order to ensure that the belt will be moved at the center of our wheels and not going out of the sidelines of the wheels’ frame. 

Then, we created a base, in which are placed the objects that will be rubbed in order to ensure our stability and security while using it. Also, a base at the side of our machine, gives us the opportunity to use various components depending on the work or the outcome that we aim to achieve. The belt used, has 72’’ length and 2’’ width. To sum up, the belt grinder is a very useful machine as you can use it to sharpen, remove a material from iron or wood, give different shapes and even polish objects depending on the grit of the sandpaper that you use. This machine is great and can be activated by the simple touch of a switch that is located on its base!

How I peel a Watermelon

This week’s structure aims to please and relax our channel’s subscribers that reached the unbelievable number of 100000.  

Therefore, we have made a machine that is capable of peeling off the watermelon and it is presented in a funny way. Although, the particular machine is not substantially useful, the procedure of making it was a small challenge for us. 

Firstly, we made a metallic frame of galvanize, square tubes 60mm x 30mm x 2mm. Additionally, acrylic of 1cm thickness was placed on the frame so the basis of our mechanism was ready. Then, having the support of lathe, we made cases out of Teflon plastic for the bearings that were used in our structure. Later, we turned a threaded rod that when it turns, it leads the knife that cuts the watermelon to keep a constant speed of motion. 

Two pulleys made by aluminum and a belt connect the knife’s axis with the rotary basis, where the watermelon is placed. Therefore, when a dc motor is connected on the knife’s axis, the axis is moving as well as the basis of our structure. Moreover, the basis where the watermelon is put as well as the cutting knife were made of stainless steel.

Most importantly, we placed a component on our structure that is located on the top surface so when the watermelon is put for cutting, this component keeps it still so it won’t move during its rotation. For this reason, we have chosen a dc motor that would enable us to control the rotations of our watermelon in order to be able to choose the ideal ones. 

Thus, providing our motor with electricity, the watermelon is rotating while the knife is moving vertically on its side and peeling it off. 

Despite that our main aim for the creation of this structure was to make our viewers laugh, the whole procedure of making it was really interesting, very functional and it involved a lot of food, too.

Homemade Metal Bender


Taking into our consideration, our subscribers’ requests asking us to make a metal bender, we could not just by making it! Therefore, the next structure by the make it extreme team with the number 0036 is a genuine idea of a metal bender to satisfy our needs. 

First, we made an horizontal, reticulated frame of square tubes of 60mm thickness x 60mm x 2mm, which has been placed on a basis. The basis of our machine as well as the horizontal frame are both motionless. A second frame with the same requirements of a structure includes our horizontal frame and it moves upwards and downwards within two metallic channels that we made. The motion of the moveable part is vertical in the motionless frame. Any moves occurred in the frame are supported with the use of a hydraulic jack that exerts pressure up to 6 tones. This jack moves with the help of a lever that has been attached on it. Thus, moving the lever, the moveable metallic frame moves vertically on the horizontal framework with the potential to exert pressure of 6 tones. Then, we placed two metallic axes of 38mm thickness at the frame which remains still and another one the same at the moveable frame. In this way, placing the metallic object between the two axes and moving the lever of the jack, we make the object incline and bend. 

At the two edges of the three axes, we placed screws and we made special channels for wedges in order to be able to put attachments according to the shape and the thickness of the metallic objects that we need to bend. Taking benefit from our structure, we made a wheel that is placed at the central axis which is located at the moveable frame. As a result, giving the inclination that we prefer and orbiting the wheel continuously, we manage a constant inclination at the metallic objects that we want to bend such as tubes, square tubes, knife blades and others. Both sides of the axes have been modified as the one side can be used for a new machine in the future. 

Also, we made special attachments for the edges of the axes made of metallic, perforated axes and plastic for bending the tubes and aluminum. Therefore, we achieved to bend iron at the center of the metal bender as well as at its edge. At the central point of the metal bender, objects of a larger diameter are placed as it is supported by both sides with omega bearing while at its edge smaller in size objects are put for bending but in various shapes and kinds. 

Also, at the edges, we can achieve a larger inclination and make circles and arrows smaller in diameter. Furthermore, we designed our structure to function vertically and horizontally according to the available space that we have and it has been implemented having the perspective to transform our structure into an automatic machine in the future using a motοr if necessary. 

It is highly recommended as it is very simple and useable as well as useful to thousand other structures and essential for us and to many other humans. 

Finally, it should be mentioned that at the sideways of the metal bender, wheels can be placed to move it easily. Also, it has been painted in green and black colour.

Dining Table

The particular structure is for the lovers of natural wood in combination with metal that we used to create a dinner table. 

This dinner table is distinctive due to the large sizes of the materials used as well as for the metallic frame and the pieces of wood. Its metallic frame is consisted of square tubes of 100mm x 40mm x 2mm, 2.20m length, 80cm width and 63cm height

As for the wood used for the particular table to cover its frame, is from a Cypriot Pine tree that was uprooted due to bad weather conditions and soil erosion five years ago. The two pieces of wood used for the frame are 1m width, 2.20m length and 12cm height. 

The metallic frame of our dinner table was coloured in matte black after it had been made in grains in order to achieve a better adhesion of the paint. Then, these two pieces of wood were connected and glued together on their two processed surfaces that were straightened to reach the best possible outcome of welding without any spaces. To empower the welding of the two points of the surfaces that were connected, we increased not only the quantity of the glue used but also we placed more layers of wood. The two edges of the table remained to the shape of the tree. Regarding the ending of the wood was made with colourless wood varnish. 

What makes this dinner table to stand out is the use of IROKO wood that was placed at the two edges of the table. Also, on the top of the table, a small, rectangle shaped piece of IROKO wood was placed to carve our team’s logo and the name of our channel on youtube as well as the structure’s number.  

This table was made to last for many years as the large sizes of its materials make it perennial. Additionally, on the bottom of its legs, we placed small floor mats to avoid damaging them in case of moving. 

The only disadvantage that we can point out for our structure is its excessive weight as it weighs about 240kg. However, this should not be considered as a serious problem as it was made for a specific place at home and not to be moved around. 

In the end of the day, another special structure has been completed and it is ready to be added in our collection!
