Stump grinding method using chainsaws and fire:
Cut your stump as low to the ground as possible.
Using a chainsaw, cut hashmarks in it as deep as you feel you can, but still getting mostly wood (vs dulling your chain in dirt/sand).
Fill up hash marks with diesel (not gas) - just a couple cups per foot at most. Has to sink in - don't top it off, etc. Don't do next step without the diesel being absorbed mostly.
Light a full charcoal chimney and pour out the coals once lit on the stump. Let it burn out.
Collapse hole with a shovel. Fill extra space with topsoil, above.
Works best after letting the stump "cure" for a while.
