Introduction: Make It Extreme's Workbench
The idea of our next video and structure came up after trying to create our working place, where we make our structures and our video clips. Therefore, we made our workbench.
Even though, it sounds simple to be made, it is not; as this working bench has some specialties compared to the most common ones. Making this working bench, our primary aim was to make it going up and down adjusting it to the proper level that we need to work in order to enable our body and don’t injure our back by taking the wrong posture while working. Also, we aimed to make it more functional, comfortable and relaxing as it is possible.
Step 1: Ηeight
The lowest level that we wanted to make it was as high as it is the ground and the highest at the 75cm as this level is the most ergonomic according to the bibliography. The reason that we wanted the nonentity in height was that in case of making a big structure in our working place to be able to have a lot of space to work and not having a long working bench taking the most of our space.
Also, the particular bench enables us to lift heavy objects and work on them at the best height. To achieve the nonentity in height, we created a cement place below the surface of the ground of our working place in order to be able to put mechanisms like the motor and other stuff in it.
Step 2: Metallic Bases - Scissors
Therefore, before placing the ground of the working place, we had already dug a place where we put a wooden mold and filled it up with concrete. Then, we made the floor and the only thing that was missing, was our structure. Thus, we made two bases, the one at the bottom which is motionless and the one on the top which moves supported by a motor as well as it is elevated at the height of our desire. Both these two metallic bases are connected with two metallic scissors that are moved on rails supported by the bearing and the more they get widely open the bench gets lower while when they come together the bench elevates. On these scissors, we connected a screw which is revolved by a jack of 240v that was modified. While the screw is revolving, it screws the scissor towards the motor as a result we have some motion. While screwing, our working bench is elevating however while unscrewing, the bench is declining. On the mechanism that encourages the upward and downward motion of our structure, we welded a whole surface of work that is 118cm x 221cm in size.
Step 3: Video
This surface of work was created using sheet metal of 3mm thickness. Furthermore, we preferred a metallic surface as most of our projects were made of metal. Finally, our working bench has a total height 120cm, of which the 45cm are placed below the ground.
