This is Merlin - George's dog. He's a lot like George actually.
Seamus had a brilliant new idea about how to make templates for placing magnets around steel rotors. We only had 10 inch diameter tortillas - they work pretty well but better is to find 12 inch diameter tortillas.
First fold the tortilla in half.
Then fold it into quarters.
Then fold one side over 1/3 of the way. (we're shooting for 12 layers here)
There we go - all correctly folded for precision placement of 12 magnets around the rotor.
Seamus showing how the end of the folded tortilla should look.
Take a bite out of it - shooting for a curve of 1 inch radius (for 2" diameter magnets to fit in). It's best if you 'center' the bite as best you can.
Then bite a hole in the middle (so that the diameter will be about 2.75 inches - this will help you center it on the magnet rotor)
Seamus stands proudly with his new magnet template.
Center the tortilla on the magnet rotor.
Carefully fit the magnets into the notches.
Not perfect... but probably workable. You could save money this way... we sell 'perfect' templates on our shopping cart for about 30 bucks. You could easily make one of these (or buy one from Seamus for about $5) and I'm sure it would work fine.
