Ive almost finished my new cooler.
Pics to come later.
Its a bucket in a bucket powered by a vacuum cleaner motor with a flat bottomed wire mesh sieve on top.
On/Off switch is from a dead Taurus (Aldi) Heatgun.
Test run appears to show more suction than my old Sadie-powered version; but to be fair the hose connection hole had developed a large leak.
Problem:
The vacuum motor driving this unit has a slide switch to vary the power.
At the moment Im running on half throttle.
Starting up at full throttle gives the bucket a hell of a jolt as the motor is only a tight fit in a hole in the bottom of one bucket (in other words not bolted in).
Starting at minimum or half is acceptable.
Indications from my test run are that I may not need full power for effective cooling. Live testing will confirm.
Any idea how this slide switch may work and what it does to the power consumed and the motor?
Is minimum adding electrical resistance to slow the motor?
If yes is this a bad thing in the long run or of little consequence.
Each use is only likely to run for a maximum of 2 minutes (way less than the vacuum cleaner was designed for).
Im trying to decide if I need to make the slide switch accessible from the outside or just leave it set and inside the cooler.
