Youtube user Tim Sway specializes in making cool things out of odd materials.
He thought that a door would be the perfect base for a bass. Pun definitely intended.
The first attempt was not so successful, with the neck taking strain.
Using better wood on the second attempt, he builds a fully functional bass guitar.

Tim’s other projects include making a speaker for an iPhone out of a French horn and using recycling for toy cars.
More projects can be found on his Youtube page.
