I am working on plans to build a mirror with a hidden compartment behind it. I'm having trouble coming up with a hidden locking mechanize though. I was thinking some sort of magnetic lock would be cool. Does anybody have any experience with this? I found these:http://www.rockler.com/product.cfm?p...1&site=ROCKLER and wondering if any body has used these "tot-loks". If so how strong are they? They are made out of plastic so I'm worried that they may break with a little bit of force applied to them. Anybody have any experience with this or suggestions?
