Hi guys
Looking to make some jerky, lots of jerky.  I am looking for some advise on what to build in the yard, smoke house wise.  I am thinking electric, for the set and forget benefits, and would like it to be mobile, so I can put it away when not in use.  
I could build a wood box with doors and vents, with a heating element in the bottom, but am worried about the box catching fire.  As temps for jerking meat range between 150-180 degrees F, I am not worried about fire when making jerky.  That said, if I go to all this trouble, I might as well make a box capable of really smoking meats, and at the higher temps required, I am worried about the wood box and the possibility of fire.  
Anybody built there own smoker?  Anybody have some tips for making jerkey?  Should I give up on the idea of building out of wood?  All advice welcome.  Thanks.
