After I saw this MAN lamp made by Ross Leidy I asked him for the SU drawings, which he sent to me. Thanks Ross! The 4 lamps are made out of beech. I made the nuts myself, but I'm not satisfied with that and that's why I'm going to order plastic ones. I can't put enough force with the round homemade buttons. Three of the four lamps I have given to my children and one I keep for myself. Just because I really like them. Something different than a wooden car. Made out of beech. The bulb is a LED GU10 230V.
I like those Dutchy and the joint knobs are a big improvement. Where did you get them?
