Synopsis: Craig Thibodeau exhibits how rare-earth magnets can be utilized to create easy but intriguing secret locks and actions in puzzle furnishings. Three such mechanisms are offered—one drawer that hides one other, a detachable magnetic pull that unlocks a drawer, and one drawer that unlocks one other—all demonstrated with easy cupboard containers. The methods rely primarily on correct drilling, cautious alignment of magnetic polarity, primary veneering to hide magnets, and non-compulsory visible clues like inlay or ornamental marks to information the consumer.
In my puzzle furnishings, I typically use rare-earth magnets to create secret locking mechanisms and different mechanical actions. Given the extent of intrigue and pleasure these gadgets add, you is perhaps stunned to see how straightforward a few of them are to execute.
Whether or not you’re all in favour of making a secret drawer to cover valuables or a puzzling lock that provides a component of caprice to your work, I believe you’ll benefit from the three choices offered right here. Creating these locking mechanisms principally entails drilling correct holes, and the magnets are available from quite a lot of on-line sources. (I like to recommend the high-quality magnets bought at kjmagnetics.com.)
Trick 1 – One drawer pulls out one otherOn this instance, the primary drawer hides a shallow, secret drawer that shares the identical pocket. Whenever you pull out the primary drawer, reverse it, and push it again into the case, its magnetized pulls drag out the key drawer.

The three approaches may be deployed in quite a lot of methods. I constructed easy cupboard containers and drawers for this text to exhibit the essential how-to. However I’ve additionally included drawings that present the right way to adapt one of many gadgets to different case constructions. The identical trick additionally works in doorways.
As we discovered in elementary faculty, magnets have poles, one optimistic and one destructive. And when two magnets meet, reverse polarities appeal to one another and matching polarities repel. We’ll be making use of each properties.
Easy veneering—I made the circumstances out of cherry plywood and the drawer containers with stable maple. I veneered the entrance of a lot of the containers with maple to cover among the magnets. You received’t want vacuum tools to do that veneering, simply conventional clamps and a few items of three/4-in. MDF to behave as cauls and unfold the clamping strain evenly.
Telltale inlay—For the hidden mechanisms on my puzzle furnishings, I wish to create telltale marks and symbols to information the consumer. I added a pair to the items proven right here as a suggestion. Or you may depart no hint in any respect, which can be enjoyable.
