The Eiffel Project

Thanks to all of you, my friends, your appreciation is a wonderful fuel to ignite my enthusiasm.

The colouring process of the first batch of pieces, to build the first stage, is completed. To help me in the painting work, that I performed using spray cans, I realized a little supporting device. My first attempt finished in a disastrous ripping of several parts who were pasted by the paint to the surface where I placed the part. This support keeps the piece lifted with minimal contact surface with the bottom of it.

Even the littlest pieces are easily kept in place during painting process. In the center of the next image you can see the result of my first attempt without the supporting device...

Now we can start with the first very dangerous task. Joining those parts along the edges giving to them enough strenght to hold the weight of the finished model is not an easy enterprise. First of all I had to find a way to keep the pieces in the exact position while adding glue and during setting. I realized a form with shape and dimensions identical to the internal volume of the base. Fixing the parts with tape to it is a good way to keep them in position exactly. I added some plastic tape along the edges of this sort of pyramid to prevent the glue to adhere to the forming shape. It worked very well.

With a very fine pipette I added CA glue along the line where the parts touch themselves. Once hardened this make a strong support to the structure.

With the fourth inner part I completed the first closed structure and can have an idea about:
1) the correct way to use CA glue to join edges of this kind of construction
2) how strong is the whole structure once the parts are joined to form a complete cage.

I was pretty worried about this first glueing experiment but now I feel somewhat encouraged: I can do it!

And placing this first batch of pieces on the printed lower side of the first floor platform... I can evaluate how good the fitting is... not bad this far...
