This lamp is made from a used tractor brake disc, two half spheres and an oak base. It is around 23cm high and I have shown a 2L bottle for scale in one of the photos.
 
The metal disc has heat marks on it and it would be easy to grind them out but I think they enhance the character of it.
 
We only have one of these in stock and parts to make a similar one are limited.
