That's a great idea. Can you get the powdered aluminum and iron oxide?
Seems like they are maybe controlled or something. But several holes
filled with this mixture would certainly tend to dry out the stump if
nothing else! I still like the idea of LOX. But what about running a
pipe into a hole drilled horizontally as near the ground as possible?
Use the oxy tank for the supply, get a little fire going with oil or
kero or wax and then supply the oxygen. If you can get the flame to
start burning deep in the hole and just keep feeding pure oxygen I bet
that stump will be gone in no time. In fact, I think I'll try this
sometime.

It's been a while since I've played with pyrotechnics but 10 years ago the
rule was that you could "only" purchase 8oz of fine pyro grade 600 mesh
aluminum powder every 6 months. 8oz doesn't sound like much but if you mix
up even 5 or 6 grams with twice that weight of potassium perchorate the
resulting firecracker will set off car alarms and bring the fire department
around. These days god only knows who else it would bring around. I wouldn't
want to find out.
