Here is an “easy to make” wooden puzzle, I made a while ago.
I found the idea from internet, and I thought it was interesting. I made a few and gave the most of them away to friends or son’s friend, but I am keeping this small one in my bag, so I can give a small quiz to anybody when there is not much to talk to the person.
Here is the video as you can see how it works (not solution, only giving you the better idea how it is made)
It takes only 30-60 minutes for one or maybe two. You can make it bigger or smaller like this, but looks good if you use nice looking hard wood, but you only need a small amount of wood anyway.
As for the solution, I think many of you guys can solve it very easily because you guys can think of it three-dimensionally. Once you shake it, it is locked, because the moving pins lock the other piece. So the holes must be a big bigger than the pins.
For those who could solve the quiz, please do not write the answer here. But to make it sure if you really got the right answer, you can make one of these and try what you thought. If you can take these 2 pieces apart 3 times in a row, that is the right answer.
For those who can’t find the answer, make one and try it whatever you think of. But be careful, once it’s locked, you can’t see the inside until it’s solved…
Have fun.
caution
Some people asked me how may pins are there.
There are 4 pins, 2 pins for each pieces. The pins are a bit shorter than the depth of holes where pins are in, and a bit longer than the width of the mortises, so the pins won’t get fall off.

DaveR,
Yes, That’s what I first saw this on the net before, but you will be happy when you actually make it and make them apart anyway. Good luck.

TopamaxSurvivor,
It is easy if you know how. Even my 6 year son can make them apart in 5 seconds.

PurpLev,
Yes, this can be a small gift if you use a good piece of wood.

I’m old, fat, slow and loosing my mind, so I should have it in 30 or less ;-)) When my 3 year old grandson turned on grandma’s computer and started his game, I figured I’d better learn how to do it too!!

TopamaxSurvivor,
Yeah, little kids can learn anything so fast! My son knows much more how to use the TV controller.

So you already made??? You better solve it soon or somebody else will show you how with what you made. I think that really makes you sad…

Skarp,
Yes, I have 2 taylor’s guitar. One larrivee. So far I think guitar from US or Europe sounds better to be than Japanese ones. But I have not tried much individual luthiers, so when I have chances, I should try some. But once you try it, and if you like it… I have to pay for it, that’s what happens all the time…
Me making guitar? No right now I don’t think about it. I know what I want to play with, and I also know that I can’t make it myself. But if you ever try, I really wanna see how it goes, so please keep posted in your blog.
