Magnetic Tumbler Parts List.
Here is a list of the parts required to make a magnetic tumbler and some of the suppliers that I have used.
*NOTE: since the list of suppliers was compiled, EBAY has become the BEST and CHEAPEST source for the neodymium magnets. Most everything else can be purchased on ebay for less than the suppliers listed here. Shop wisely!
