For what it cost me Phil, I'll probably just use it as is for a while and be on watch for a clay oven. I ended up paying about $260 for the tandoor and everything else for the day. This Pakistani steel tandoor normally sells for $320 new if you can find one. They are quite cheap and not well made so really it probably isn't worth the trouble.
First thing today, after marinating the chicken, is to make up some type of steel baffle plate to sit in the bottom. I think it is meant to have one. The guy I ended up buying the skewers from is a retired tandoor chef who has just closed down and sold 4 restaurants and a home delivery Indian food business. He advised me to put one in and use charcoal in conjunction with the gas to obtain better flavours. He is selling 3 commercial clay tandoor but they are far too big for my needs.
