P.S im after some tandoor liner photos inner/outer and if possible a cross-section diagram i have good idea how I'm going about it but more info i can gather the better! if anyone can help? Thanks UB.
You may recall a photo I posted last year of an improvised tandoor which I tried to knock up from a pile of bricks. The one lesson I learned was that bigger is probably not best, as a large oven simply needs vast amounts of heat energy, and therefore fuel, to get it up to tandoor type temperatures - say 500C. Given I'm not aiming to cook restaurant type quantities, the next tandoor I try and build will be much, much smaller.
I'm glad my tandoor was only a temporary construction - easily dismantled - or I could have been left with a huge oven of little use.
