Today I was in an industrial area outside of munich to visit a wood and a metal dealer. The wood dealer, which is called „Götz“ has a huge warehouse with big planks. You can only buy them like they are, delivery is very cheap with 15 €.
One plank costs roughly 50-200 € and they have a great selection of wood.
I also went to the metal and Plastic dealer „B&T“, but unfortunately they don’t sell if you didn’t order in advance. But the great thing about their website is, that they show you the price, which seems to be uncommon for metal retailers.
After calling and visiting several carpenters, I think I finally found a good source for wood. After calculating what I need detailed I will order and start the prototypes.
