So here is my problem.

I made a small box with sides roughly 5/8 thick. I put the lid on and than decided to use 1/8 inch rod magenets as a lid catch. I drill the holes in the side and lid of the box, put some super glue in the hole and put the magnet flush into both the lid and side.

I than close the lid to make sure the magents are lined up and that they catch and to my surprise the catch doesn’t work. There is no resistence in opening the lid. Now I know what most of you are thinking that I must have installed the magnets wrong and have the magnets facing the wrong way so they repel, but the magents are properly aligned and installed so they should attract. I think the problem is that the magnet is 1/8 in size and is likely just too small exert an effective force in securing the lid.

So here is my question, I now have a box with two small silver magnets that arent effective and not really sure how to proceed. Any thoughts on how to solve this problem?

Magnets are not easily drilled so I would try to use a solvent for the CA and maybe some air pressure squirted along side of the magnet to pop it out.

Just a thought.

If you use solvent for the CA, how about a stronger magnet to pull out the embedded one!
Just a thought….

First did you try putting a small piece of metal between the magnets just to see if they are contacting each other? Second, I would leave the magnets where they are and add others that will work for you. You can always paint the magnets if they are too distracting, (Use nailpolish, every color of the rainbow available).

I would leave those magnets in, and install larger ones further apart so that there is no magnetic interference… maybe even cover the smaller ones with wood to hide them in (I usually WILL hide magnets IN with a small wooden disk on top).

Also – I never use glue to permanently install magnets in wood – if you make the hole the right size, the magnet should sit snug inside – believe me – it’ll still be hard to pull out – from experience.

You may need the ends of them closer to the metal serface they attract to kep the box closed. Magnetic force decreases or increase by the square of the distance. A little ways can be a lot when you are dealing with things that change expotentially.

Well if this isn’t weird!

So I decided to leave the magnet in and was going to add more today, about 3 days after installing the magnet. I just went to open the lid and to my surprise the magnet is catching! I’m happy and confused. It seems that the magnet has gained strength, how is this possible? I can now turn the box upside down and the lids stays closed, something that certainly didn’t happen when I installed them a few days ago.

Very weird.
