Intro: Angle Grinder Hack 5
Not only it was an enjoyable experience but also a very amusing one creating this angle grinder 5. In the particular episode, our aim was to make a vehicle that would be able to move through an angle grinder. Having this in mind, we started making a velocipede (a three-wheeled bicycle) that is driven by the rider having a standing position.
Step 1: Frame
First of all, taking aluminum bars of 50mm width and 6mm thickness, we managed to make the framework of our bicycle. The reason that we used aluminum in our construction is to make it as lighter as possible. Then, we bended these bars to give the shape that we wanted according to the curves of the shape that we had chosen.
Step 2: Mechanism
At the frontal part of our velocipede, we used the frontal part of an old bicycle. While at the back side of it, we made a base that would support the angle grinder. However, the main problem in our construction was the transmission of movement from the angle grinder to the wheels. The reason of the particular problem is that the angle grinders spin a lot (11000 rpm) but to make the wheels move, it needs more strength and less spinning.
To solve the particular problem, we took the mechanism used at the lawnmower. This mechanism is urged to spin through the lawnmower’s mechanism and this move is transmitted to the wheels by lifting a lever. This lever is connected with a handle by a wire rope. Therefore, pressing the handle on the wheel, the move is transmitted from the angle grinder to the rear wheels. The particular move from the angle grinder to the lawnmower’s mechanism was achieved by using a belt and pulleys.
Step 3: Pulleys
The pulleys used, were made by aluminum on the lathe. The pulley that was used to be placed on the angle grinder is 4cm diameter while the pulley placed on the mechanism taken by the lawnmower is 9cm diameter. In this way and using the mechanism of a lawnmower we managed to decrease the spins of the wheels and increase its strength as a result our bike to be able to transport our weight.
Step 4: Wheels
Moreover, the wheels that we bought and placed at the back side of the bike are 20cm diameter and they are used on scooters. Even if our little bike is not powerful enough, it works incredibly fine and it can provide you a very enjoyable riding and a lot of fun.
Step 5: Video
Finally, the message that we wanted to pass across making the particular construction was that recycling and maintaining various old objects and accessories from old machines as well as keeping other old materials, we manage not only to keep our environment clean but also we can make impressive constructions.
