Hand Crafted incandescent light

MY FIRST WORKING LIGHT BULB

This is the actual lamp making starting point, or the first success. Bulb is worked for only 20 min, but it was a clear sign and motivation to continue work! At that time I had no tools, pumping station, only a little bit of knowledge and strong will to make my dream come true.
