So lipless bases, how to magnetize them, especially trying to keep things thin? Take Renedra bases for example. Their bases are 1.5mm think, but if you want to make them magnetic what would you do? I can think of three ways. 1. Magnetic sheeting 2. Metal sheeting 3. Magnets. Thought is to be thin. 1. Magnetic sheeting. Cut a matching size circle and attach underneath. Prob is the stronger stuff can be thick causing the base to thicken up past what you desire. 2. Magnetic sheeting, like roof flashing. Cut a matching size blank to match the base and attach underneath. Bonus is the flashing is thin and won't increase the base thickness much. 3. Magnets. They come in all shapes and sizes. But drill a hole through the base and place the magnet in the hole and glue it in. Now the magnet may be thicker than the base which means it will stick above the base. This can be covered up by basing material maybe. So what other ways are there that I dont know about? Let me know. Grimm
