JNorton - First, look at the fuselage construction and wing construction examples on my web site to see how I use the magnets:

I get them from the Magnet Source. You have to buy 100 of them to get them at that price. I bought 200. THey are the EXACT SAME as the ones that come with the Great Planes board. Be sure to get the right product number. They have two identical style magnets - one has the hole drilled in the plates and the other style doesn't. You need 10-24 or 10-32 screws to attach them.
