Still requires an ignition source -- but what are you doing with black powder in your wood
shop anyway?

You find it strange that someone sat in a cubicle and put the piles of
sawdust exactly where they wanted them, then set a pile of sawdust on fire
with a spark from a motor and then allowed a series of ever expanding
explosions to eventually destroy an entire plant in a massive conflagration?

You would rather have seen the real thing?

Are you volunteering your shop for such a video?

With enough black powder you could probably get a good secondary
explosion of dust.
