The tandoori oven is a large stoneware pot from India,
with a small opening at the bottom for air.  
I placed it inside a large steel drum, surrounded with vermiculite for insulation.
In this pic you can't see the vermiculite, as it needs topping up. 
.
After filling with vermiculite, the top goes on:
A propane gas burner is adapted with a long pipe
 to sit at the bottom under a grill, which will
hold charcoal,providing a dual heat source.  
The gas gets the charcoal going,
and provides a quick boost at any time.

The oven is connected to a portable propane tank, and ....
voila!  Naan da yo!
