The same process can be made much easier using a layer of dried chips staged in untill you have a drum full of hot coals and a layer of ash on top. As he does. i would start with straw and sticks as well to create space for the initial burn but follow up with a good layer of chips. when it starts to burn through dump in another layer. keep this up until you have it topping up. His wetting process is sensible as well. What i would add to all this is that i would then use a stamping pole on the coals in order to speed the crushing up of the carbon and reduce it it in size generally. I would go as far as to run it through a quarter inch mesh as well in order to reduce the rest as well.
