Oven for charcoal cooker

What method are you going to use, direct, semi-direct or indirect pyrolization? Are you going to load it, light it and shovel the charcoal out? (direct method) Load it, light it and once burning close the door till it stops smoking and seal it till it's cold? (semi direct method.) Or, place a sealed container packed with wood in it, build a fire under it and let it cook till it stops smoking and extinguish it? (Indirect method)

I look forward to pics of it in operation and reports of how it works.

Indirect method, it took cook time from 6hrs down to less than 2. Need to put a dampner on the chimney and make some doors for it. Built it to help control sparks from fire.
