I made a cheap one that differed slightly from this in that I used a ford coundty wheel with a bush in the middle. A length of car exhaust wass free to slide in this and air from an old cylinder vacuum blew down into a hole created by boring with a saw. As it burned the pipe fell to the soil beneath. Trouble was it took quite a while to burn and stump gobblers were readilly available by 1984. Also fires in general were frowned upon by then.

 

The big dead pine stump it was most successful on gave the householder a fright as we left it running overnight and he was awakened about 4:00 by the noise of a roaring jet and an orange glow filling his room. There was a long flame from the flue ( I had no termination on it and the plastic hose attached to the exhaust pipe was reduced tothe helical wire reinforcement) by the time we turned in to work the stump was gone, even tunneled out some laterals. The soil had turned from grey bagshot sand to red which I guess was the iron in the soil changing valecy.
