Electromagnetic Uncoupling That Works!

[Gary S]

Installed a few of the e-mags today. Here is how I do it.

First, mark the cork by using the magnets as a template.
   

Then cut out the cork with a hobby knife.
   

Drill holes down through the foam and plywood to locate the location underneath.
   

I made a template to mark the hole.
   

   

Used a jig saw to cut the plywood. Be careful not to use a blade that is too long because it will cut through the cork above.
   

   

Next is cutting out the foam from above. The foam has to be cut out from under the cork on the edges due to the taper of the emag.
   

Insert the magnet up through the foam and use screws to attach it to the plywood.
   

And the installed magnets. The height is adjusted with the screws - the top of the magnet is level with the top of the cork. I'll put a piece of duct tape over each magnet to cover the hole.
