Making a tube bender die



Besides the machine, essential for bending a tube is the dies that are used by it. These dies are responsible for the homogeneous and accurate bending of a metallic tube.

The different sizes of the dices enable us to bend different kinds of tubes in thickness. A common way of making them is with the use of a tool that is used in lathe and it is called "internal spherical turning tool."

As we didn't make such a tool, we decided to show a different way. First, we modified the piece adjusting it to the right size and then we placed it on the dividing head. The size of the tube that we were going to bend was 42mm therefore we should remove a 21mm hemisphere from our piece by perimeter of our cylindrical piece. Therefore, we regulated our fly cutter when it rotates to shape a 42mm circle. We also, regulated it at the centre of the piece horizontally and vertically. While the fly cutter was spinning, we were moving 2mm in the piece and using the division head we were creating a complete rotation of the piece. Repeating the same procedure we inserted 21mm in the piece creating the perfect dice for our machine.

Finally, as we completed it, we used it for bending a tube for our next project reaching an unbelievably good result.

Making a Wood Chipper



The wood chippers are constructions that are more and more in demand because they are very useful for various reasons. The wood chippers are machines that cut the branches and tree boles into small pieces. If you are keen on treating the trees and the gardens well, this causes the gathering of branches that are cut down. However, using a wood chipper the branches will be cut down into very small pieces therefore they will take up less space and their recycling will be easier too. These small pieces can be used to become a pellet for wood stoves as well as fertilizer for the soil. There are lots of types of these machines and each one has its pros and cons. 

The machine numbered 0103 is actually a big flywheel that has two blades on it. While a motor is spinning with high speed the flywheel the blades are cutting the big pieces of branches into very small pieces. Behind the blades, there are 4 wings that make air from the blades towards the exit of the machine. In this way, the branches are inserted from the entrance of the machine and after being cut, they are pushed by the feathered wings supported by the air that is created and then they are tossed out of the machine.

Finally, because the machine is for domestic use, it uses an electric motor 4hp for its movement. The performance of the machine is absolutely impressive and we are really satisfied with the outcome.

Making an Electrolysis tank



Electrolysis owns number 102 in our constructions. Electrolysis is the procedure of decomposing a substance supported by electricity. It is used for the export of pure metals as well as for plating. 

First of all, we started making our construction by taking an old, plastic container of 45x45x45cm size. Then, we made a metallic frame with wheels, on which we placed our plastic container. Thus, it can be easily moved to be cleaned. To be able to move the electric cargo, we modified a transformer taken by an old microwave. Therefore, we modified the transformer in order to exit 13v AC and then supported by a bridge, we turned our exit into DC. 

Regarding the cleaning of the metals from the rust, the negative pole is located on the piece while for the plating we do it the other way round. As we filled our tank with water, we put some washing soda in it and then we sank the rusty metals in the liquid. The outcome of it was unbelievable as the rust was vanished completely from the metallic piece.

To sum up, we are very excited with what we created and we are looking forward to trying it for various kinds of plating such as copper plating and nickel plating.

Making a rivet nuts tool



There are many times that we need to screw two thin objects together and we are unable to make a fold due to their thin width. The solution to this problem is given by the rivet nuts that is an already made fold and when it is pressed, it remains still in the hole that is located. There are lots of tools for the placement of rivet nuts especially manual ones.

Our construction numbered 0101 can be used manually or be placed in drills. The philosophy of this tool is very simple. Firstly, we put a screw at the lathe that has the shape of a hexagon at the back side in order to be able to be placed at the tools. Rotating the screw with the help of two thrust bearings, the screw spins without moving as a result the nut moves as well that is located on the screw.

This system is placed in the tube that we made on the lathe of 52mm width. On the nut, there is a keyway in which there are two stable screws which are attached to the cylinder. Therefore, when the screw spins with the hexagon part, the nut is not able to be spun so it is dragged into the cylinder forward and backward accordingly whether we are screwing or unscrewing. In front of the nut, there is a spot where the proper adaptor enters according to the size of the rivet nuts we enter.

In our case, we made an adaptor to be able to place the rivet nuts of m4, m5, m6, m8, m10 and m12. Although, our tool is very convenient in use, we believe that if we used a hydraulic tool, it would be better.

Making a monotrack bike


Starting this project, numbered 0100, we knew that it had to be something special in order to thank our viewers for their loyalty. Having this thought in our head, we, therefore, decided to make a motorized vehicle. We called it ‘monotrack bike’ as it has only one crawler that it uses it to move. To make this crawler, we took a car tyre, from which we removed its two sides to make it softer and easier to take the shape that we want. Then, using an aluminium, diving bottle, we made the rims, which transmits the motion of the machine to the crawler.

Firstly, we used a machine by a 100cc 2 stroke scooter. The crawler takes its shape and spins in 5 additional metallic rollers that we created and are made of a metallic tube 80mm wide. Three of the five rollers are located at the frontal part of the bike and are connected to the machine with a variable connection so that the crawler will be able to be set along it. In this way, we can control its stretching. The other two rollers are located at the back side of the crawler and through a scissor are connected with the frontal part of the bike, where the three metallic rollers are. The scissor is supported by three springs which help the absorption of the noise of vibration. 

This construction functions similarly like the monowheel that we created in another video. However, instead of being inside the wheel, you are sat on an elastic crawler.

Summing up, while getting into the process to start this particular project, we knew that despite the constructional functions, there would also be problems turning the wheel during its driving. However, the vehicle was moving with great facility even better than we expected. It also gives us a very pleasant feeling during its driving as the driver feels like he drives a motorbike on one wheel. Finally, we are very glad that such a unique construction is included in our collection.
