Hello,
Now the chains are glued to the side linkage rod; big moment when I inserted the rod inside the chain ring!!! no trembling allowed, swearwords accepted!
I noticed a little mistake: the brake wheel is not enough close to the steps! too late!!
Attempt of painting today: too hot for the spray outside; I will see tomorrow morning........
After the important comment of PRRHORSESHOECURVE about the air tank (thanks to him), I sent to my "3D guy" the drawing in .stl file to make them for me; it's not important if I put them later on the platforms at the same time as the walkways.
