So the first test went well .
first i set the temperature to 230 f (110c)
i put my Thermometer in the middle shelf and i got 237f(114) .
next i set the heat to 293f (145c) the thermometer showed 293f(145c)
i gave it 2 hours to burn and after 2 hours at 293f(145c) i got 298f(148c)
the box was not hot on the outside so the isolation worked well .
i just think that i will have to add a smoke generator .
i will have to test it with some ribs when i will be back from vegas in the mid november . added a small touch as it is my first prototype with GMG .
i think i will send them a photo .
The legs are holding ok as it is not so heavy .
