Welcome to Overunity.org.uk
Okay where does David Hamel and the Hamel Spinner come into this?
Well this guy has been milling around for a few years now and most sites that
played with his ideas have not been updated since 1999.
To save me waffling on about who, what and where. Please check the links below that are all related to the Hamel Spinner:
There are many more web pages and doing a search on www.google.com for hamel spinner should help wet your appetite.
First Tests with Hamel Spinner.
Well first thing is, ignore all the web pages saying that magnets should be
this type, this size etc etc. Ignore the part of leaving one magnet out and
drilling a hole in the plastic rim.
Be aware that it is a bitch trying to get a number of magnets around a hoop with all their North sides facing in, but it can be done.
In the picture below I used a 100mm flu vent that is used for the 4 inch
toilet fans found in the UK.
As you can see by letting the magnets push away from each other instead of glueing they form a even spacing.
Next I got a steel ball used in a 1 1/16" PinBall machine and attached it to
a OD50 x ID20 x 10mm NdFeB magnet. The force of the magnet held the steel
ball in place, so no need for Glue!
Next get a piece of PlexiGlass and lay the ball+magnet on it. Lower the 100mm ring slowly down towards it and yep indeed when the height is correct it starts to spin.
Excuse the bad picture but trying to hold the magnet and take a photo at the
same time is diffiuclt!!
I am lucky in that I have a CNC machine
http://www.cncdudez.com and a mini lathe and the Jigs below
along with the wheels took about 1 hour to produce.
Okay so above we talked about the Hamel Spinner and yep it worked, but was it the hand movements that kept it going????, because the spinning ball and magnet does not hang around and you end up moving your magnetic ring around following it.
So next is to create a static model of the Hamel Spinner, where the middle does not move and see what happens.
Find below Disk One where the Magnets are mounted on a wheel.
This has 8 magnets all evenly spaced around a 200MM wheel. All the North
Poles point upwards.
Find below Disk two where the Magnets are mounted on a wheel.
This has 8 magnets spaced offset around a 200MM wheel. All the North Poles
Okay here we go
With Disk 1 it did not spin at all, with Disk 2 and the offset configuration,
well that was a different story!!!
I will post more details as I now start to play with different configurations to indeed see if we can get the Hamel Spinning disk into a working format,
Sorry I am not posting the results of my experiments as
this would take too much time.
