Peal the bark off when you get it , you want no bark.
Best to dry for 2-3 weeks but can be used green , just takes longer.
Here is how I do it.
I buy a new paint can from home depot with a lid , tin 1 gallon one. it will last some time if stored in a dry place..
Punch a hole in the top about 1/4 inch round. Cut the wood and split as fine as you can without cutting fingers off , he he. so it stands up in the can.
pack it in there , put the lid on and put a roofing nail in the hole. gas can escape but air can,t get in.
Get three beers , put the can in the gas grill and enjoy.rite on the flames.
any fire will work.
It will begin to smoke and the gas will catch on fire , that's OK. 45 min to an hour smoke stops , let cook about 10 min more and remove can "DO NOT REMOVE TOP OR NAIL" or the coal will burn.
When very cool pour this into a 5gallon bucket , get more beer and repeat!
I use a 4 foot long 2X4 to crush it up in the 5 gallon bucket.
sift to remove any uncooked wood.
you can make enough in a few hours to last all year.
I use white pine but willow makes a hotter powder.
