I've decided that I am going to design this drum to do four functions.
1. Smoker (non-diffused and diffused) using 1 or 2 cooking grates and 3rd grate for optional diffuser medium.
2. Grill (adjustable fire basket can sit up higher right under grate for grilling)
3. PBC-Like (hanging meat from rebar & hooks--will stop holes for the rebar with stainless steel bolts, washers & nuts when not using this feature.)
4. Rotisserie -- again I'll stop all the holes with bolts, washers & nuts when this feature isn't being used.
If this works well, I might get rid of my mini wsm, hasty bake and weber kettle.
