Aluminum cube.

Hello guys, I´m glad to see you here again. Today I want to explain to you, how is working on our laborious aluminum cube. First of all, you must know why we are working on an aluminum cube. The reason, train, get better, develop and acquire hand skills. As it´s obviously a good mechanic must have a great knowledge of the use of its hands, cause all that you must to do is with them. To do it, we must follow some rules with specifics tolerances, with them we start from a large tube of aluminum, from it we cut many sections. Every student must to take one and then, starts the nightmare hahaha. With the piece, you go directly to the lathe cause you need as minimum one perfect face. Next, we cut the cylindrical piece to give the form of a cube, here starts the first exhausting work. With a saw you must to cut over 5cm four times. This work gives you the feeling of not doing anything. It´s very very slow work, trust me. It´s the same as a snail moving. When you have cut all the faces comes the moment of the file. If cutting you have the feeling of not doing anything or the same as seeing a snail moving, the file will remember you the same as seeing a snail in slow motion. For sure you are going to spend many many hours until you start to see the light at the end of the tunnel, and another amount of hours to complete all the cube. Once you have finished this two works it's time to check if you have done a good work respecting the tolerances. When the tolerances are just the size of the thickness of a paper sheet. In this point, the nightmare ends, the exhausting work it´s done. The light isn´t shinning cause that's not all the work to do but you have advanced a lot. It´s very comforting. To continue  it's moment to mark the piece to lateral drill. In a first moment you think that is an easy and fast work but... PAAAM, unexpectedly comes a sudden knock from nowhere. Probably for me, it´s the hardest work. As I said we must to follow several rules to mark the cube and to do correctly the holes. Once we have marked it, we can start drilling. Fortunately, this part is done with a machine if not we will continue suffering the nightmare. The foto above correspond to this moment. A subsection; while I Washington writing, I saw a little mistake. Every work done in a workshop, you must before do it, follow the safety rules, in this case, the mistake it´s that I wasn't using the safety glasses. Don´t tell it to my teachers shhhh it´s our secret hahaha. Continuing with the cube it´s time to ream, that means to pass through the drilled holes the reamer to remove all the burr and impurities and at the same time  polish. It´s incredible the precision of the tools because when the ream it´s finished, the reamer passes through the hole perfectly without "dancing" inside. If you try to pass a simple hair between the reamer and the hole you will see that it´s impossible. Now we have the cube, all the holes with different sices done and now it's time to make the thread. This time there´s no automatic tool again. With a screw thread and your hands in three steps or sizes, you will slowly doing the thread, fortunately, the through holes doesn´t need to be thread. Once all the threads are done the following step is to set all the screws and bolts, in total 20. The screws and bolts are special to break after being set, using a special lockwire. This part for me it´s the best one because lockingwires entertain me a lot. Again we must follow special rules to lock them. At this point, finally, the light it´s shinning, the cube its done. I remember that at that moment I looked back thinking: "finally after hours and hours and hours of cut and polish and all the steps, the cube it´s done". The feeling it´s very comfortable cause after hard work, you have the shimmering prize in your hands.
