Make it Extreme's Crane
In this week’s video, we came up with the idea of making a crane in order to improve our ‘make it extreme’ shop and include another useful tool in our collection. The crane is a very useful tool in a workshop for multiple purposes such as lifting heavy objects that we need to work on as well as lifting things that we want to paint and according to each user’s needs and imagination its uses get multiplied. Therefore, we made our crane on our workbench in order to enable us to lift objects on it.
To start with, we primarily made a rectangular, metallic framework of 4 meters length and 76 cm height made out of square tubes with dimensions 60x60x2mm. Then, we filled the rectangular framework with square tubes’ pieces of 60x40x2 that were placed in a 45-degree slope at the right and left side of the rectangular framework and in this way we managed to form our netting. The purpose of the formation of this netting is to multiply its tolerance in lifting heavier loads as much as possible.
Carrying on with our construction, two metallic rails were placed on the framework, on which our winchi of the crane will be moving forward and backward. Afterwards, we made another metallic, netting framework but smaller this time and we put 4 heavy, metallic wheels and an electric winch that is able to lift 500 kg on it.
The particular construction moves along the 4meters framework in order to be able to lift objects from various positions at this length. If we wish, we could make it move in 4 different directions but in our case this wouldn’t work as our space in our workshop is limited so it can service our needs as it is.
Regarding the portable part of the crane was made with a slope so that the slope of our foundation will be counterbalanced and the weight of the objects will be exerted vertically as well as the loads will be allocated accordingly. Additionally, the portable part is inclined outwardly so that it won’t be removed from the rails regardless the weight of the load placed on it.
There is also, another safety valve that is located where the winchi is. To achieve this, we placed a metallic plate below the winchi that will stop the drop of the winch in case the screws that support it get removed.
Finally, we would like to declare that we are absolutely satisfied with our construction as our workshop’s potential has been increased. Now, we are able to lift a load and move it easily as the portable part of the crane slides in a very low power and combined to the ‘make it extreme’ work bench, the usefulness of our space is amazing.
Electric Drift Skatekart
On the 50th video of the ‘make it extreme’ team, the construction that is presented is a vehicle. This vehicle looks like something between a mini go kart and a skateboard. Therefore, the name that we gave to this construction is a ‘skatekart’. Our main aim making the particular creation was to make a special skateboard that would drift. This construction, besides a means of transportation and a vehicle of entertainment, it is also a construction that has multiple aspects of interest.
Firstly, we took some metallic pieces from a treadmill machine and then we altered them making the metallic framework of our construction in order to apply all the other pieces of the vehicle on it.
Afterwards, at the back side of the framework, we placed 2 bearings, in which an axis of 70 cm long and 20 mm thick is passing through it. Also, two wheels and a pulley, which moves according to the motor were placed on this axis. Additionally, the wheels that were placed at the back side of the vehicle, were made out of a black Teflon at the lathe. We chose this Teflon because it is harder than the white one and regarding the aesthetic aspect it is better in this case.
The wheels that we made, were placed on the axis with aluminum components, which were also made at the lathe in order to achieve the simultaneous rotation of both the axis and the wheels. The wheels made of Teflon have 12 cm diameter and 13 cm length while the pulley, which was placed on the axis, has 10 cm diameter.
Regarding the frontal part of our vehicle, we have chosen rubber wheels in order to achieve the required stability while turning the vehicle. These frontal wheels have 10 cm diameter and 10 cm length. The particular wheels are used for other purposes but after our alterations that we have applied on them, they have become the ideal ones to be used as frontal wheels for our vehicle. The turning of the frontal wheels is controlled electrically by using a motor and a mechanism of an automated window from a car as well as some pieces of a car’s wiper that we used to make our system.
Using this motor of 12 volts, a battery and the switch of the particular mechanism, we created this system. Therefore, when we turn the switch on the right, the vehicle turns right as well. While turning it on the left, the vehicle also turns left.
Regarding the motor, we used an electrical one of 1000w, 48v and 3000rpm. It is a very powerful motor for such a vehicle but we faced many problems in order to be able to control it as we didn’t have the controller of the particular motor. The batteries, which were used, weren’t the proper ones but the high cost of the suitable batteries made their use impossible. We were willing to use a lithium battery but instead we used lead acid battery. Thus, we had an excessive weight and less performance as well as tolerance. The motor was being activated using a relay switch, although due to the start and the excessive use, the relay switch was damaged.
Also, the cover of our vehicle was made of a piece of aluminum, sheet metal. The cover was decided to be painted in the competitive colours of the repsol of the moto gp. Moreover, we did a test drive of our vehicle on slippery surfaces, on the streets and on soil surfaces.
Our final conclusion is that is very entertaining to drive such a vehicle on slippery surfaces as you can drift without exceeding the speed limit and being in danger. To be able to drive this vehicle on the soil and on the streets, one of the surfaces should be stuck on the wheels with Teflon tires so that our vehicle won’t be too slippery. During our trials, we used an anti-slip tape and the performance of our vehicle on the soil was changed immediately. Undoubtedly, this construction will be an unforgettable experience to us as we enjoyed every single second of making this project!!!
Electromagnetic climbing like a Spiderman
The 49th video came up with a very original and extreme idea. Our primary aim was to make a tool that would enable us to climb on a metallic building and generally on anything made of metal. So, as it is obvious, the fundamental part of our idea was to be based on electromagnets.
Particularly, we decided to make four electromagnets placed one in each leg and in each arm. Then, we made a bag filled with batteries that would provide energy to our system while the switches would manage our pace. In particular, we took four old microwave ovens that we found in a rubbish bin and we used their transformers for our construction. Next, after cutting the transformers in the middle and only keeping the first spool, we managed to make four powerful electromagnets. With constant experiments, we achieved to shrink the size of the electromagnets as much as possible as well as to increase their power. Also, we drilled the electromagnets in order to be able to place them on a basis and on the human limbs.
Regarding the electromagnets that we created for the upper limbs, we made metallic handles that would be used to place our hands to pull the weight of the body upwards. At the point of the handle, we chose a metallic tube with small dimensions in order to have less weight, good hold, convenient grip to support the body and space to put the switches that would control the pace.
Regarding the lower limbs, we made a basis, where the shoes of the user will be placed in a way that the most load of the weight will be supported on the tiptoe in order to leave the electromagnet unaffected from the constant increase of the body’s weight. Therefore, when the human steps on a particular point that will be located on a further point of its tiptoe, the multiplication of the load will not be a problem.
Moreover, to keep the electromagnet stable in the shoe, we made special points in which scratch belts were passing through to ensure the stability and the adjustment in any size of a shoe. For the handles, we used one of these scratch belts that keep the handle stable in the user’s hands from its wrist while at the lower limbs, we used two belts in each limb to ensure stability.
In order to make our mechanism easier to use, we used a push-off switch. Thus, as long as we do not press our switches, the electromagnets are activated while pressing them, the electromagnets get deactivated.
Initially, we connected the left arm with the right leg and the right arm with the left leg as it is the normal gait of human. However, we realized that it was easier to connect the function of the right arm’s electromagnet with the right leg’s one and respectively for the left limbs as well.
Whatismore, to prove that our construction functions properly, we put metallic blades of 6 meters long on a two-storey building and by using 4 batteries of 12volts, we climbed on the top of this building.
Although, the climbing on a flat wall of a building reminds us a science-fiction movie like the ‘Spiderman’, the particular construction was very interesting and adventurous to be made. Even if our construction is the only original design, is efficiently functional but it definitely has the potential of improvement regarding its weight, comfort and functionality. The point at the handles where the switches were placed is quite convenient and functional.
Considering all the above, if we were in a place to reconstruct such a construction, we would pay more attention on the more ergonomic construction of the bases where the shoes are placed. Even if the particular construction has no use besides providing us entertainment, carrying out this project we realized how useful the electromagnets can be and how powerful they are in lifting great loads of weight by just getting energy from some batteries. Finally, we are completely satisfied and thrilled by the adrenalin given to us making the particular construction.
Make it Extreme (1 Year Highlights)
Welcome to the make it extreme channel!Our channel aims to provide fun, inspiration and food for thought to our viewers by watching how structures are made in our workshop. Also, by making furniture, engines, tools, toys, vehicles with passion and using our imagination we are trying to give our own ideas and solutions to solve any mechanical problem in the field of structure!
On this video we don’t present the making of any construction, we show a unique manufacture that was created many years ago by the channel.
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.
This structure is capable for multiple uses such as removing the rust from old objects and coatings as well as writing on many different kinds of materials like glass, stone and others.
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.
Another essential structure 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.
For this STRUCTURE we were INSPIRED from many videos uploaded on youtube where people use HOVERBOARDS for entertainment.
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!
This structure aims to please and relax our channel’s subscribers that reached the unbelievable number of 100.000. Therefore, we have made a machine that is capable of peeling off the WATERMELON and it is presented in a funny way!
Another very useful tool was added to our workshop with the structure that we made this time. It is a ‘positioner table’ that can be useful for a great range of areas related to the MAKING of structures.
ANGLE GRINDER HACK SERIES
I just had the idea of making a metal frame which will be screwed and attached on my angle grinder and a propeller which would be attached at the point where the discs would normally be placed.
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.
The third angle grinder hack from the ‘make it extreme’ team was created to help us in garden chores. Therefore, we turned the angle grinder that we made into a strimmer!
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.
This time by using the battery angle grinder, we managed to make an improved version of the angle grinder hack 4!
Plasma cutter circle toolYou 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!
Thank you everyone for the support!
Rotary Positioner Table
Another very useful tool was added to our workshop with the structure that we made this time.
It is a ‘positioner table’ that can be useful for a great range of areas related to the making of structures. The role of the particular table is to spin a metallic plate on the right and on the left according to which way the stepper is pressed.
This table is able to spin the metallic plate from 0 degrees- 100 degrees with spinning speed already regulated. It may sound quite simple and not useful at all but imagine to manage stable welding while the piece is spinning in gradual speed. I can ensure you that the welding will be easier implemented automatically and much more uniformly. Equally easy would be if we put a router in a stable place while spinning a piece of wood, then we would immediately get a trimmed wooden perfect-shaped circle. Additionally, it would be also easy if we had the plasma cutter still while spinning the metallic plate. These are only some of the multiple utilities of the particular table as using your imagination, its functions are countless.
Everything started when a friend gave us a gearbox that is capable of making the 10 spins in just a single one. Then, we found a dc motor from an old fitness machine and we connected it with the gear box. Therefore, the motor with the use of a speed controller could be spinned with 0-3000 spins so when it was connected with the gearbox, it was exited with 0-300 spins. From the gear box, we managed to make an axis of 65cm on which the metallic plate was applied and it is also the surface of our project. This axis is also supported by another two bearings in order to achieve even higher endurance. As the already mentioned pieces were connected, they were placed on an axis with 40mm thickness that has the potential to spin all the pieces made from 0 degrees to 100 degrees. Using a crank and a shaft that is covered with screw threads, (the screw threads begin from the one side of the shaft reaching the other side), we made a system that when the crank is spinned, the whole system spins as well as a result we get the inclination that we need to work on. All these are moving on a metallic base that was made of square tubes with dimensions of 50mm x 50mm x 2mm. On this metallic base, we also placed a mechanism which is role is when the position is chosen and it is the proper one to work and bolt the screw, the table is stabilized completely and securely.
One of the advantages of our own design of table is that when it is positioned in a horizontal place at the 0 degrees, two surfaces are appeared that you can work on both, one at the front side and one at the back side of the table. In particular, at the back side you may have a chuck and be able to put smaller objects while at the front side, where the surface is bigger to work, you can place bigger in size objects.
The motor that was placed to move the table left and right, uses two contactors that are activated by pressing the two steppers. The steppers are made of aluminum sheet metal while their covers are made of plain sheet metal. Additionally, above the steppers, there is a board where the switches are placed. One of the two switches is there for an emergency in case a problem is arisen and it can be pressed to deactivate any function in progress. While the other is to activate the whole mechanism and the potentiometer placed next to it, regulates the spinning speed of the metallic surface of work. Regarding future uses of the structure, various bases where made that many supporting tools and machines can be placed multiplying the potential uses of our structure. Concluding, in this way we managed to implement another project of the make it extreme team with a great success. Therefore, our workshop is one step ahead being more fulfilled.
Also, we believe that the particular structure was worth our time and efforts not only for the satisfaction gained during making it but also for the great usefulness of the particular tool.
