Hello bottlefed70, cheers for your quick reply.since writing askin for more pics,my very good friend at work is going to get me the sheet metal i need,he is a metal smith and gets it cheap via work..oops! naughty naughty! i told him about your filing cabinet idea, so if i show him a series of pics (all during working hours at work of course!) he can then do all the calculations and the metal work etc. then when i am up to doing the other bits and bobs i will read up or ask for advice form you experts.pity i cant find a bigger filing cabinet or up right fridge etc...once complete the oven will be located in one of my workshops at work

don't worry i will look after the electric consumption...honest.
many thanks again
grommit.
