Lockwood-Hiller pulse jet engine - photo

[DIYSwede]

Excuse my ignorance, but I see what is described as a jet engine clamped to a workmate which seems to be resting on a timber baulk. Why does it not take off?

Given its size, the produced thrust would be in the 40-60 lbs range,
bolted and clamped to a Workmate tied to a railroad tie, it should apparently be good enough.

A bigger issue could be the glowing stainless setting the table top afire,
and the neighbors complaining: its blaring could easily be heard 5-6 mi away. YMMV.
