Eureka!

We decided to have the first BBQ cook out of the year yesterday after returning from the School Summer Fair . I didn't fancy taking out the wooden floor of my cold smoker so dusted down an old, large kettle BBQ we got from a DIY store years ago because it was cheap. A Weber it ain't It has no controlllable lower vent just a coin sized slot in the side of the bowl. If you cook with the lid on the charcoal goes out, with the lid off you have flare-up meltdown. I'd been meaning to put it on a skip.
So... I drilled a 10mm hole in the base of it, took a piece of 10mm copper tube and forced a flange into the end so it wouldn't drop through. On the other end I connected the 45litre/min air pump I cold smoke with. I placed an upended perforated stainless steel fruit bowl over my air input and a bag of self lighting charcoal on top of the bowl, with a scattering of ordinary charcoal around the bowl and lit the bag. As it took I made sure the charcoal was distributed evenly around the fruit bowl and once all the paraffin burnt off put on the lid with it's vent fully open.
It quickly settled down to 146 deg C, measured on the probe inserted through the lid vent. 3hrs later it was still reading 146 deg so cooking was a dream. At this point I took the lid off and open grilled some more food, the charcoal stayed well behaved with no flare ups and I later removed the BBQ grid and did a stir fry with a Wok sitting on top of the fruit bowl.
I must have got 5 hours cooking out of 1.5kg charcoal,before we retired for the night, and it was still warm at lunchtime today.
I'm now repeating the experiment to ensure it wasn't a fluke, with burgers and sausages for lunch then a chicken for supper. Photos to follow.
