I needed to weld two pieces and, given the finesse of these steel parts, my arc welding station was not suitable, it would have melted everything. He is a young mechanic from my neighborhood-retro Performance-who brought all his know-how to make me embarrassed. Let him be thanked! What will be the use of these pieces: even if the departure is in 10 days, I keep hoping to add to my prototype the icing on the cake imagined from the beginning of the project: the possibility of orienting the solar panels in the direction of the sun. This orientation would be carried out on a single axis of course, the axis of the trajectory of the bike, and only the days without wind.
