Upcycle your chopped tree into a rustic design lamp.
Use a slice of wood for the base.
The copper along with the wooden slice makes the lamp look very robustic. Due to corrosion the copper will turn green after some time, and makes your lamp kind of alive.
Then make a stand from copper pipes. Use compression fittings to make the angles. They’re quick and easy to use, and require no special tools.
