The largest project I have undertaken so far was the construction of a bar on our porch. In addition to the woodworking challenges, I had to accommodate water and electrical connections.
The body of the bar is ipe, with the two bar surfaces made of padouk. These two surfaces have been left with sapwood and their `live-edge' shape. The copper in the bar was pounded (by me). The sink is copper, as is the faucet.
The doors for the bar are held together by copper rivets, four in each corner. These can be seen in the pictures below. You can also see the outlet covers in the shapes of fishes (requested by my wife), made out of padouk.
The back of the bar is tongue-and-groove ipe, with copper inserts.
