My neighbor tried something like that, only at 5am, cutting wood until 10pm or so, with a commercial lumber chainsaw with no muffler.
Needless to say, the next morning at 2am I decided to burn trash. I cleaned out my room and basement, and the garbage consisted of atleast...
Last year's fireworks (LOTS of M-100's, Screaming Moon Rockets, Whistling fountains, etc)
6 half full propane bottles
Two 1,000 strip firecracker rolls
10 aerosol cans
1300 rounds of old ammo
400 old 12 gauge shotgun shells
100 old 16 gauge shotgun shells
30 12 gram CO2 cylinders
more stuff that I can't remember
...and 5 gallons of gasoline, five gallons of diesel, 2 gallons of motor oil, and six old trailer tires. Well, lets just say he never pulled that stunt again.

I had to get a new burn barrel afterwards, but it was worth it. You could feel the heat for like a 200 foot radius, and that barrel glowed like the nose on the space shuttle.
