@ Kallen I have this keg , it is a spit. Now thinking this may work better.
It has a stainless steel tray to hold the heat beads, but this could now hold the chips.
I can put the beads in the base of the keg'
As per that last link is that all the wood[chips] you need ???
At least with this keg I can controll the heat better, cooks a mean roast.
used to take it to 4x4 shops in the morning and have it ready by lunch time. HHMMMmmmmmm
