Bernoulli ball tricks
Flame throwing (to be added later)
And more probably...
Step 1: Parts list
One aluminium lamp shade
Nuts and bolts
3-core mains cable
Resin for glass-fibre
Various ad-hoc bits and pieces
Step 2: The clockwork
The front-end beater & brush assembly failed and the drive-belt snapped.
The vac was replaced.
So I had a spare electric air-pump. The machine was deigned for sucking, the blow just went to waste. Trying to block-up the exhaust vents and divert the output wasn't much good because the case was leaky. Also I'd got a big redundant bag-space and handle.
I took the whole thing apart and stripped out the essentials.
I'm not going to tell you how to take a vac' apart any more than: use a screwdriver and break things.
So I extracted the motor and fan unit, plus the TRIAC speed control, on-off switch and the variable resistor which links into the TRIAC.
Step 3: The motor
The motor sucks air in the back, and vents it out the front.
Depending upon your perspectve, this either cools the motor or heats the air.
It's a friction-fit, with a rubber band. I needed a new case, and after a few weeks patience found the aluminium lampshade.
I've added 90' angle-brackets to space the motor from the metal-case, but there's still the friction-fit.
The motor was bulked-up with double-sided foam pads and tape, finished with the original rubber band.
A tight-fit, requiring much pushing and finger-work but just right.
