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.

Making a chisel hammer


Reaching, eventually, the 0099 project making a hammer this time, according to our taste and needs. There are many kinds of hammers and each one is made for specific tasks. Hammers can be made by various materials and in many different methods, but we decided to use lathe as the main tool for our construction. Therefore, we made a chisel hammer. This hammer is used to transfer the power of the hammer to the chisel as a result the chisel will then remove some material to the wooden surfaces. 

Firstly, we made the head of the hammer using a brass in golden colour and which is heavy enough for its size. We formed the head of the hammer to the shape that we wanted and we got the diameter we needed so that our fingers can be placed on it during its use. Then, we drilled it horizontally and we made a thread to be able to screw the grip.

The grip was made with aluminium to achieve a light weight. Even if the aluminium is a relatively soft material, in this case of our hammer due to its design and to the way the user holds the hammer, the grip allows almost no loads during its use. Therefore, making our hammer in this way with minor hits that are more controlled, great power is transferred to the chisel.

To conclude, this hammer is effective and enables us digging in metal and wood that require accuracy. Besides the uniqueness of each handmade hammer, such a creation improves the skills in the lathe and other tools.

Making RC steam boat



A remote-controlled, aluminum boat that needs gas and steam to be moved is our new construction with the number 0095. It is commonly known that there are more efficient ways to move this remote-controlled, small boat like the electrical motors as well as the internal combustion engine. However, this time we chose this way as we found it a constructive challenge and a good learning around the matter of moving something using steam.

Initially, we made a boiler from stainless steel 316, in which you can enter some water. Also, by making a Verner for propane, which passes from the middle of the boiler, the water heats and is turned into steam. After making the boiler, we had a pressure test at 100 bars in order to make sure that it is suitable and tolerant to lower pressures that will be produced from the pressured steam. Next step, we modified a vane motor for air, on which we put a propel that causes the movement that is produced in the water. All the prementioned pieces are placed on an aluminium boat that we created.

We also, used an aluminium sheet metal due to its low weight and its flexibility to be formed. Our aluminium boat is 110cm long and 35cm wide. Additionally, we placed the propane tank at the front side and the boiler at the back side of the boat. Further, we placed a tube in the shape of a spring to increase the steam production in the boiler as well as to achieve a greater surface of water heating and to avoid the liquefaction of the steam when it moves towards the motor. 

Regarding the handling of the boat, we put a receiver that receives the demands coming from an RC controller in order to enable us to give orders from a distance. Thus, using one of the levers of the controller we turn the boat to the right and left through a flap that is located behind the motor which is moved by a servo motor 25kg. In addition to this, to move the motor, we activate a 12v steam electro-valve placed on the controller and when it is activated the steam moves with pressure from the boiler towards the motor in order to achieve the spinning of the propel and in extent the move of the boat, too.

In the last step, we painted our boat to the colours that we usually paint our motorized constructions like orange, white and red. Even though, we applied a lot of changes and trials at the end we managed to have a good performance of movement and function of our construction. The total weight of our boat is quite a lot as it weighs 25kg. We must admit that we are proud of our creation and very pleased that we managed to move our boat using steam. Who knows?! Maybe in the future, we will make more vehicles that will be moved by steam.
