The neck goes through the body, and is held on at the other end with a single screw. The strings simply go through the rim of the kettle. I put some leather and a bit of an old wooden chopstick there just to make sure that the loops of the strings wouldn't get broken by the metal.
The middle two strings snapped, so I have extended them with copper wire.
I currently have it tuned GDGA# and am having a lot of fun playing it.
