I'm not too sparkling on electronics, but I remember years ago that
our old hoover used to go on 'blow' instead of suck at the flick of a
switch, someone told me that if you wire a motor in the opposite way,
IE connect live to neutral and netral to live, it spins in the
opposite direction, although I've not tried it.
My idea is to make a minature blowing machine of some kind, for
various jobs and just for ****ing about with, so if I reverse the
connections around in the motor, will it do as I want and start
blowing or will it just blow up? - I'm not too bothered if it does
the latter as I've got quite a few, also, do I need to make this
connection at the motor end or can I just reverse the wires in the
plug?
Or is it a non starter?

TIA

It hasn't occurred to you that a motor that sucks also blows out of the
other end? Isn't it easier to just point the existing exit at whatever you
want to blow at?
Many years ago, parents had an Electrolux cylinder cleaner. That had a
connector under the filter/outlet air vent - you could connect the hose
to that. IIRC they actually sold something like a spray gun that was
intended to work like that.
