The only siginficant problem is if the hose gets blocked, either
with a large and coarse plane shaving, or because I put the
nozzle too close to a surface when using it for general cleaning

three-pointed cross section.

I had exactly this problem in my early experiments. It
can be solved by using a galvanised steel dustbin instead
(assuming you can still find one of course).
