Chain Saw to concrete groove cutter



Construction number 0091 is a very convenient tool for the constructive industry. This tool can make two canals simultaneously on the walls of a house and then the material used for it can be removed easily between the two canals to place the piping and many other things. Another very good use of it is the opening of the canal on a concrete to be able to put the metallic clew for sliding doors, the cutting of the stone as well as of the iron. In simple words, our construction is a chain saw hack.

Firstly, we took a tree-cutting machine and we removed the chain that cuts the wood to place a small gear for a chain of motion transmission. Next, we made a metallic framework, which on its edge there is an axis that spins in two bearings and at its centre the prementioned chain passes through. Thus, when the tree-cutting machine rotates then the axis spins too.

In each of the axis’ edge, a disk is inserted in a distance of 10cm. Then, we made the threads of the axis counter clockwise so that when the disks find resistance, they won’t be able to unscrew and slacken. After that, we took two protective covers from an angle grinder and we placed them in order to use the tool with safety. 

At the beginning, we were quite hesitated regarding the fact how efficient this tool would be but after using it we got impressed by its accurate, fast and functional cutting. Also, a huge advantage of it is that it is portable so it enables you to transfer it even to places where there is no electricity. Changing the disks and placing a disk for cutting metals it  easily enables you to cut metallic objects, too.

Engine driven hydraulic power unit



Most of the machines that we make are hydraulic as this kind of systems have great power and multiple applications. We have been using our tools in the shop as the hydraulic unit that we use is electric. Therefore, in places where there is no electricity, our hydraulic unit cannot be used. For this reason, we created a petrol-powered, hydraulic unit, which is capable to move our hydraulic machines not only inside the shop but also outside of it.

Firstly, we took a petrol-powered engine from a mowing machine and used some pulleys in order to connect a hydraulic pump on the engine. Then, we made an oil tank, from which the oil is derived and taken by the pump to send it where it is needed through a controller. Thus, we placed a manual controller. 

To sum up, this construction is very useful because it can move tools that enable the user to cut and drill various materials and lift big loads to spots that are electrically inaccessible. Although, this construction is easy to be made, it is very interesting and it has great usefulness.

Making hydraulic cutter and spreader



Inspired by the fire fighters' tools, we decided to make a hydraulic cutter, which will help us to our constructions. Most of us have already used scissors of cutting metal that is moved by the strength of hands.

It is a good tool but after using it for many hours it can be painful and tiring. Thus, we took the hard jaws from a hand scissors and we adapted it to a hydraulic piston.

Initially, we made a 50mm piston. We put a metallic piece on the piston and on this piece we adjusted  blades that are connected with the jaws of the scissors. As the piston is moving the blades are functioning as levers that open and close the scissors. The scissors that we used, it can be used for cutting metals of up to 12mm thickness. We could cut thicker metals  if we used bigger scissors.

Additionally, we made two calipers, which are placed on the same piston and they open and close from 0 to 25cm. This tool has multiple uses depending on the user's imagination. For example, it can lift a machine, pull out a wooden ballet, open a door etc.

To sum up, using this tool, we found it more comfortable and handy than we primarily thought. Therefore, at the 0089 place of the make it extreme's collection of constructions is owned by this amazing tool.

Making hydraulic puller



In many cases the people, who are occupied by making constructions, normally they have to remove pulleys from a motor or machines as well as ball bearings from axis and many other stuff. Therefore, we made our own tool for helping us in these cases. However, we tend to come across to pulleys and ball bearings in various sizes and as almost every time, the distances vary too, we decided to make a tool, which would be able to be adjusted in order to avoid using many other different tools. 

To achieve this, we used a hydraulic piston to provide us with a massive power of attraction and pressure without stressing ourselves. There are a lot of kinds of this type of tools that are hydraulic and others that provide power by using a screw. 

Initially, we started our construction by making a piston having an inner diameter of 30mm and ability to exert 3,5t in 250bar pressure. This piston can cover 15cm distance. Then, we screwed the piston on a metallic flange, on which sockets were located to enable the pieces that are caught on the pulleys and ball bearings to be inserted there. 

Also, we made enough accessories which are combined the one with the other according to each case that we come across every time.

In conclusion, we made this tool in such a way to be able to work like a small hydraulic press to put ball bearings, to bend metals and to drill various materials. We are very pleased with our tool’s performance as well as with the ergonomics of this tool with the number 0088.

Making an extending bicycle #3


The third part of the construction 0087 has been completed in a very pleasant way as our construction was completely functional providing us with a great pleasure. At the third video of our construction, we placed a motor of 1000w and 3000rpm on our bike in order to be able to be moved electrically. 

Regarding the power supply of the motor, we used the construction made at the video 0084. Going back to that video, is demonstrated how we made a battery that can move a bicycle without using our feet for about an hour. The motor and our battery are 48v. The speed of the bike is controlled by a throttle that is located on the steering wheel. 

Our electric bike’s speed limit is 43km. The motor was attached to the back wheel with a chain which is not connected to the pedals so if the rider lets the pedals still the motor will move the bike. 

Then, we removed all the pieces of the bike and we painted it in colours of orange, red and white which are the colours that we normally paint our vehicles. We also tested our vehicle at the seafront of our town aiming to expose it to many people and to entertain them with the presence of this unusual bike. 

Finally, when the bike stands tall at its highest level is 1,85 tall and the head of the rider reaches the height of 2,80cm tall, which is a very high point compared to a normal bicycle. We are very satisfied with the great function of all the mechanisms of our bike as well as with the people’s smiles in the presence of this unusual construction!
