Built the teepee as described in postmans thread as found by gumbi . 20 X 10 foot tarp formed into a 20 foot diameter semi circle with 10 foot radius . Measure 6 equal segments along the circumferance and attach tie downs . Cut out smoke flaps and attach at top . Find six dead Ash saplings . Make a tripod and then just lean the others on . This supposedly makes a 10 diameter teepee but with sagging etc its a bit less . So I added the left over plastic to the bottom as a skirt . Find two more saplings to attach smoke flaps to . Adjust smoke flaps to form venturi . Found the interior to be too smoky for me even tho flaps are drawing well it seems fire will have to be split wood and burnt hot .
