Angle Grinder Hack 6



This time the 6th angle grinder hack by the make it extreme aims to give a solution to the problem caused by the branches and leaves gathered after the pruning. Our main aim of creating the particular hack was to make a machine that will be mobilized by an angle grinder and it will cut the leaves and branches into small pieces in order to enable throwing them into the bin later.

Initially, using the lathe, we made an axis, on which 12 small chains were placed. These chains are similar to the ones used for cutting the trees with the only difference that the ones that we used are very tiny. We also made a metallic box having both an entrance and exit and it covers the chains and the axis that is supported by two bearings located at the sides of the metallic box.

Finally, connecting the angle grinder on the axis, the axis with the chains revolves with 11000 spins (rpm) and the chain’s teeth cut any wooden item inserts in the metallic box and because of the speedy spinning the wooden object exits like a sawdust. Therefore, the branches take much less from our space now and there is no need burning them.

Make it Extreme's metal vise



Extremely essential is the tool made in this week’s project and it could not be anything else but a ‘heavy duty metal vise’. Starting with its shape, we kept the common shape of the vise applying a few modifications giving our own shape and size considering it as the ideal one for our workshop. Already having 2 big bars that we used in a previous video, the one showing the electromagnetic climbing of a Spiderman, we decided to modify them and use them in this tool too; each bar is 12 cm wide and 16 mm thick. 

Firstly, we used a metallic flange of 10mm thick and 30cm diameter as a base. Then, we conglutinated many pieces of bars together and we formed the trunk of the vise which has a rectangular hole at the center, in which the mobile part of the vise is dragged. The immobile piece of the vise at the front part has a socket, where grabbers in various shapes are applied and therefore many options are provided to us according to the reason we want to use it and the shapes of the materials that we use to work with. 

Also, another socket was created at the mobile part of the vise located exactly at the same height and width with the immobile part of it as a result when the mobile part shuts, the object which is located between them is immobilized. The mobile part is dragged through the hole that exists at the centre of the immobile part by spinning an axis using a thread. The advantage using this method is that we have very few flaws and more power in holding it as well as we manage to be millimetric precise in our work.

The axis with the thread that we made on the lathe, was made by stainless steel to avoid creating rust and flaw in this particular, functional piece. Therefore, when the thread is revolved on the right, the mobile part of the vise moves towards the immobile part and the vice versa. 
Finally, to achieve enough strength, we made a big lever that gives us the advantage of power to spin the axis with the pashas exerting more strength and in extent holding anything placed in the vise using more power. The total weight of our vise is 204 lbs-92.7kg.

Make it Extreme's Fat Bike


This week’s project takes us back to our childhood memories as we have made a bike. We have not applied any special modifications regarding the functional parts of the bicycle compared to a common bike made in a factory. However, there are quite a few extreme variations regarding its design that make ‘our’ bike of the make it extreme team seem unique. We got inspired by the fat bicycles that exist in the market. These bicycles are called ‘fat bikes’ as they have wider wheels than the common bicycles. Therefore, our general idea was to make a fat bicycle that all his parts would be ‘fatter’ than all the other common bicycles.

First of all, we removed the tires from an immobilized car to use them on our construction. At the frontal wheel of our bike, we placed a bearing and we adapted it on a single prong which is attached to the wheel that is being moved and stabilized by the bearing which is placed at the beginning part of our bike’s frame. The bike’s frame is made with a tube of 4 inches thickness while the frontal prong and the scissors placed at the back are made with a tube of 3 inches. The scissors at the back is the part that is connected with the back wheel of the bike. We placed an axis with a gear at the back wheel of our bike that is moved supported by the pedals through the chain.

Although, the construction of a bike sounds simple and usual, it requires accuracy and patience as there are a lot of pieces needed to be made and placed, where the lathe is located. Also, the frame must be precisely made on a straight line to prevent any problems that might be arisen during riding the bike. Even though, we thought that our bike would be very heavy during riding it, we got amazed realizing that it was actually comfortable and light as well as it was pleasant driving it. Finally, we painted it in the racing colours of Repsol Honda like we did in our previous construction of scatekart.

Making air compressor



On our 61th project, we made an essential tool for every workshop. The construction that we have created this time is an air compressor. Even though it is a common tool, it is useful for cleaning as well as using tools that air compressor is required. 

Firstly, regarding the machine that compresses the air, we used a compressor taken from an old air-condition and for compressed air tank, we used an old bottle of propane. Although, this construction is relatively easy to be made, a lot of dangers are lurking so it is required to be careful and experienced. Taking the bottle of liquid gas, we first unscrewed the valve in order to remove the residues from its content. Then, we filled it up with water to clean its content completely and remove any other liquid or gas included in the bottle. Next, we made some holes where it was necessary and we conglutinated some rusks in each hole. These rusks have the same fold like the accessories that we put in a later stage of our project.

The dangerous part of our construction is at this point, where the air tank is located as any tank that accepts air needs to be checked and tested in a safe way to ensure that it can handle more pressures than the daily amount of pressures as there is the risk to be violently exploded and cause serious damages and injuries. Therefore, after finishing with the conglutination on our bottle, we sealed it and we tried it with water pressure so that if it is exploded, it won’t be so serious and violent. We tried our bottle at the 25 bar. For extra safety, we used a safety valve regulated at the 8 bar and we also used an electronical switch that stops the compressor’s function when the pressure reaches the point we set. 

In another socket, we placed a pressure controller connected to two other holes, where the tires are located as well as the tools. At the bottom part of the tank, an air faucet was placed that was opened to clean the tank from the air and the humidity that was collected due to the compression.

Lastly, at the last socket that we made on our tank, we connected the tank with the compressor so that the air, which pressures the compressor, passes through the tank.
At this stage of our procedure, we should mention that to make the compressor work between the connection of the tank and the compressor, a blow off valve should be used to prevent the air from the bottle to return back to the compressor. Additionally, when the function of the compressor stops, the compressed air remained in the compressor is removed to enable it to restart easily when it is instructed. 

Finally, it is a very interesting and easy project that needs great cautiousness to avoid any dangers lurking. Even though the compressor taken by a broken air condition has the ability to compress up to 35 bar, we regulated it to work up to 8 bar, which is sufficient for the use that we want it. Also, a final tip from us, using a compressor taken from a fridge is also good as you will get a very silent machine.

Extremely heavy fidget spinner



For this video, we got inspired by other youtube videos, in which youtubers constructed various spinners and each of it had its own particularities and characteristics. Therefore, the team of ‘make it extreme’ decided to make its own spinner and make our own experiments on that.

Firstly, we cut a whole piece of a metallic axis and using a lathe we turned its shape into conical. This piece consists the point of connection between the spinner and the ground. Then, we put a flywheel that was taken by an old fitness machine on this conical, metallic piece. The flywheel moves without being affected by the piece that touches the ground. The total weight of our construction is 38kg which is considered as excessively heavy for a spinner. 

Moreover, on the flywheel we put many metallic angles creating a winged perimeter. Also, using the power of air that blows on the angles that were placed there, urge the flywheel to spin. Thus, using a sufficient power of air, our whirligig can be span in a great speed as a result it is inert and balanced enough preventing to be dropped on the ground. Therefore, as long as the whirligig spins it keeps its balance, too. 

Finally, to get experimented with it, we also placed two pedals above the whirligig in order to be able to balance ourselves on it being ensure that it is inert to be dislocated during its spinning. Our conclusion is that we need a much heavier whirligig which can be span in a much greater speed as we managed to keep our balance for just a few seconds on our spinner.  To sum up, although as it seems a not so useful project, it was interesting and we spent a pleasant time making it!
