WHERE TO GET PERMANENT MAGNETS

LATEST INFORMATION IN 2004

For my Axial plans you need to choose either 2" x 1" x 1/2" magnets or metric 46 x 30 x 10 mm magnets.
And then follow the 'English' or 'metric' units in the alternator construction after that to make them fit OK.

You can get the 'English' 2" magnets from

Magnet suppliers worldwide - based in Colorado - great discussion board.

OLDER MAGNET INFO PAGE:

FOR THE BRAKEDRUM DESIGN, YOU NEED FERRITE MAGNET, CERAMIC OR SINTERED - NOT BONDED - GRADE 3 (OR 8 WILL DO). IF YOU CANNOT FIND THE EXACT CORRECT SIZE, ASK THEM TO CUT THEM, OR BUY SEVERAL AND STACK THEM.

NEODYMIUM MAGNETS (NdFeB) ARE LIGHTER AND MORE POWERFUL AND CAN BE USED INSTEAD, BUT YOU WILL HAVE TO CONTACT ME PERSONALLY FOR HELP WITH CHOOSING A SIZE TO TRY.

IN THE UK TRY CERMAG 0114 244 6136

OR TRY SHAWS
