DIY Spot Welder

The new project of make it extreme is the transformation of an old microwave oven into a brand new spot welder. How did we manage that? Firstly, we decomposed the microwave oven and took its transformer and the fan that cools it. 

The particular project was planned not to make a portable spot welder but one with a stable basis.
Therefore, we made a metallic frame with a stable basis to support it and we also made some holes on it in order to be able to be screwed on the spot where it will be located. After that, we removed the one copper coil of the transformer and we passed a single coil of a copper cable through the frame, 16mm thick in order to reduce the volt and increase the ampere. Regarding the edges of the cable, we made two copper spikes 25mm of thickness. Then, we placed the cables with the transformer on the metallic frame and after that, we put the spikes on two calipers. The one caliper that is located on the frame remains still while the caliper which is on the upper side opens and closes by just a simple touch on a stepper that we placed on the basis of our machine. Thus, by just stepping on this stepper the calipers close and come together enabling the electricity to permeate the spikes. 

Additionally, a spring was placed on the moveable caliper that brings it back to its original position when we release the stepper. To regulate the pressure between the spikes, we placed a mechanism with a spring on our stepper that keeps the stepper moving even if the spikes come together.  

On the upper side of our machine we placed the control panel that regulates the thickness of the pieces of the iron plate that we need to glue together. On the control panel, we made a timer relay switch that defines the time needed for the weld and as it is commonly known when we glue thicker objects more time is required. Therefore, we have the potential to define the time needed according to the thickness of the material that we glue aiming to the desired outcome. Beside the timer, there are also two indicative lights and a switch on the control panel. When the stepper of our machine is not pressed, then the red light is pressed indicating the machine is not ready to start the weld. However, when we press the stepper and the light is not red anymore but becomes green, we know that it is ready to start the weld. Starting the weld and pressing the stepper, electricity permeates the spikes as well as the metal sheets that we need to glue within the time period that is set. 

Therefore, the weld is carried out through a safe, controlled procedure. Moreover, the fan that we took from the microwave oven and we placed it behind the transformer keeps the transformer’s temperature low enabling us during the weld process to carry on gluing endlessly.

DIY Barbecue Table

The other day, while I was discussing with my uncle I got inspired by his words and so, I made this barbecue table

The philosophy of this table is that anyone can bake whatever he wants and for as long as he needs to make his food. However, a few problems arose creating it such as the overheat, the weight and the decay due to external factors like the weather conditions. 

The capacity of the table should be for 12 people, so the large length of our manufacture (250cm x 120cm) needed a metallic frame from the inside in order to prevent any deformations because of the excessive weight of this table. 

Therefore, we made a metallic frame using a square hollow section known as square tubes 60mm x 60mm, 220cm length and 100cm width with four legs 73cm tall. At the central point of this frame, it was made a socket to place the barbecue. Then, the whole top surface of the frame was lined with cement board which is used for fire safety. Regarding the final surface of the table, we used marine plywood which is water resistant as well as to the rest frame, we used the same kind of wood. At the central point under the table, a wooden box was made that covers the barbecue in order to protect the user from the high temperatures that are being increased. Thus, to increase the performance of our structure and to protect this wooden box, we lined the internal side of the box with Rockwool, which is heat insulating material and then we also placed cement board for fire safety. 

The barbecue has the potential to be removed and put back to its place in order to be able to be easily, cleaned. The edge of the top surface remained to the natural colour of the wood while the rest of it became black. Then, the whole table became clear varnished. Additionally, we should mention that on the days, when the table won’t be used as a barbecue, we made a wooden cover to be put on it in order to make it seem as a common table.

After completing our manufacture and testing it, we remained satisfied from the outcome as there was no increase of the temperature in spots where we needed to be heat insulated. We were pleased realizing that with a very few coals, we could bake our food on our barbecue table for three hours or may be more. The only expected problem that we faced was the smoke that was caused by the baking. Although, this may lead us to another manufacture, which will be an extractor fan to collect the smoke that will be gathered by the table. 

Finally, we would like to thank all the ‘make it extreme’ friends for their help and support and for the great company!

It's possible to use the angle grinder as a belt sander!

The second angle grinder hack from the ‘make it extreme’ team is here and it aims to transform the angle grinder into a belt sander

We needed a belt sander that would be able to rub wooden surfaces very quickly. However, we made this angle grinder hack instead as the belt sander would be costlier and also, because most of the manufacturers have and use at least one angle grinder hack in their work. 

Therefore, we made two aluminum wheels with a ball bearing in their inside part so that the sandpaper tape will be able to spin on them. Also, we made a system that controls these two aluminum wheels to open and close with the help of a lever which was placed at the one side of our manufacture. For example, when we pull up the lever, the aluminum wheels come closer and then, we can put our sandpaper. Additionally, we have placed two springs that pull this mechanism in order to keep the tape stretched. 

Also, at the one side of one of the two aluminum wheels, we made a system that controls the movement of the tape from right to left so that it will be able to be adjusted at the center of the two wheels. One of these wheels is connected with a belt to the angle grinder and it has been placed, exactly above the whole structure. 

Therefore, we have in our hands an angle grinder which can be sat on its base and be linked with our structure. Finally, once we turn it on our belt starts moving and the belt sander starts working too.

DIY Plyo Box

What we haven’t really thought since now, is to create a manufacture for people who love working out and keep fit.
Therefore, the team of ‘make it extreme’ came up with the idea to create four pedestals in four different heights so that the athletes will be able to perform their jumps from the ground to the pedestals and vice versa.

The usability of this construction is multiple as these four pedestals can be used by many people for various purposes such as by healthy athletes to increase the strength of their saltation, the intensity of their jumps as well as their kinetic function while it can be also used as a tool of rehabilitation for various musculoskeletal injuries. 

What makes this construction so special and unique is that these four pedestals can be put the one inside the other for saving space into small sports centers and rehabilitation centers.   

The heights of pedestals are 30 cm, 45 cm, 60 cm and 75 cm tall accordingly while the surface on the top of the construction is according to the height in order to have a normal landing on the surface of the pedestal according to the difficulty of the saltation… It is definitely worth to be mentioned that the surface for landing expands according to the level of difficulty and how high is the jump in order to ensure safety during the saltation.

Regarding the base of this tool, we placed rubbery floor mats to prevent the collapse of our construction during the jumps.

Plasma Cutter Idea

You have probably noticed that the circular cutting of iron plate is very frequent in our manufactures and all the manufactures in general. This thought led us to our next creation. 

We designed and made a tool, where the plasma cutter could be placed and revolved. In this way, our electrical protractor revolves and supported by the plasma cutter cuts the material in circles, rings in the size that we have chosen. 

This remarkable tool uses an electromagnet of 12 volts that is capable to lift 100 kg in order to ensure the tool’s stability on the iron plate. Therefore, our tool remains stable on the iron plate and a caliper revolves around the stable magnet with the motor’s help. 

The head of the plasma cutter is placed on the caliper having the distance that we want. Our particular tool moves both forward and backward so that the cables won’t be tangled. Consequently, when all the switches are ON this tool is automatically activated and it revolves removing the part that we want. 

Most importantly, it is relatively cheap for its capabilities and the help that it provides. According to the size that we have chosen to cut our circles, we set the ampers of our tool accordingly. Our manufacture is able to cut a material in circles of 10cm diameter to 100 cm! Finally, having this tool in our hands gives us the opportunity to make a fast and a very accurate cutting.
