If ya have a metal 55 gallon drum use it. 3 or 5 at a time preferably. Watch videos on YouTube about it. It works really well pretty quick. Put them over the tops of them and burn some wood on them and they'll burn like a fuse down deep. They have to be dry too tho.
Yeah I was pretty impressed when I saw it done. I suppose if you don't have barrels some rolled up metal flashing will work also. Just needs air holes near the bottom. But any large metal tube that keeps the embers piled up and working thier way down as they burn will work I guess
Basically yes. It keeps the coals from rolling off the exact area where you'd want it at too. If I was you'd I'd get a large oversize drill bit and drill some vertical holes deep as possible into them prior too, then dump some old burned motor oil etc into them just so they burn alot quicker and take light better. If they're old pine tho it may not be necessary. But between burns of coals you may wanna take the barrel off and dig off any large build up of soot off them so the new added coals will be against the actual stump as much as possible.
Gotcha. Well you can still do it cheap by doing this first then powerwashing the roots up that are left behind instead of digging them.
