Despite the fact that an inexpensive suitcase looks pretty decent, there is a very serious justification for its low price — this is the quality and durability of the materials from which it is made.
However, let’s open it and see everything. And in parallel, I will tell you what it was like when you bought it and what had to be modified to use it.
We unfasten the zipper around the perimeter, and the inner world of the suitcase opens up to us. I’ll tell you right away — this is already a modified version.
And in its original state it was like this. The body of the suitcase is made of thin and very fragile plastic, which could not withstand even the first trip.
The decorative plastic on the handle turned out to be no less fragile and split off.
The retractable handle began to fall apart into two halves, but I noticed it in time and rewound it with black duct tape. Blue, of course, would be more reliable, but it would have violated the color scheme of the suitcase.
One of the wheel mounts almost fell off the body, thanks to the same fragile plastic — the rivets were simply turned out of it.
In this photo, this problem has already been eliminated thanks to the modification inside, but more on that below.
When I found that the suitcase was literally falling apart before our very eyes after the very first trip, I did not want to admit defeat and throw it away, especially since I paid 1,500 rubles for it when buying.
A light but rather strong material (red in the photo) was at hand, from which elements were made with the help of a knife to strengthen the structure of the suitcase — the bottom wall, the top wall, the back wall and the lining at the points of attachment of the handles.
In addition, I bought a rivet and rivets, as well as washers for rivet diameters to increase the contact patch. And, in fact, he reassembled the suitcase. He became noticeably stronger.
This modification was enough for one more trip, after which one of the legs of the suitcase fell off and was lost. But I considered it uncritical and put my suitcase away for the next trip.
On the third trip, my wife and I felt how uncomfortable it is — when the suitcase constantly tends to fall. And I decided to give him another chance — to make a new leg out of wood. Moreover, last year I managed to acquire a CNC milling machine.
For greater reliability, I decided to mount the leg not with two screws, but with four.
I drew the outlines of the halves of the leg and created a control program for the machine.
I secured the workpiece to the machine. In this case, I used beech 20 mm thick.
Then he pointed to the machine «zero» along the X, Y axes and zeroed along the «Z» axis using the contact pad.
I started the program and went to drink tea, while the machine cut out the necessary parts for me.
After milling, I lightly go through it with sandpaper.
I tighten with clamps and leave for a while to allow the glue to dry.
Next, I make markings and drill holes for attaching the legs to the suitcase — there are 4 of them, in the corners.
I screw the leg into place with four M3 screws using washers.
A slight bias came out due to the fact that I used two native holes on which the lost leg was held, and they were made crooked.
As a result, the suitcase became stable again, and I think it will withstand more than one flight.
