I found this posting, and this is a call to revive Greyman from any grumpy kelleykettle talk, in the form of a more solid request for wisdom, from him or anyone else:
Ive got a small oil drum working well I think, but I wonder about the kids of wood to use. I got a shock last week. I used to use nicely seasoned hard wood, thinking this was best. it usually took 4-5 hours before the smoke changed colour and I could close it down. Then last week I tried some seasoned larch - softwood. It took two hours, and I was able to able to empty the drum and do another round all in one lazy day in the wood. I checked it out last night on the braai (BBQ), and it worked very well.
Tell me, do you guys use soft wood? I also wonder about green unseasoned wood? What would happen if i used that?
Cheers and thanks, Steve
