This would be some nice work for a CMM router

Look at the Dovetail Puzzle



I have seen one made with a router only the single dovetail

You first look at it and you know it can not be opened

I have one of those just like your pic that I built back in the '80s. Sitting right here under under my monitor. Mine is walnut and maple. The walnut grain is a dead give-away.

Had a 5th grade teacher that had made a bunch of wooden puzzle that he called "burrs", 5 to 12 piece's in each. They were a lot of fun. If you got all your work done early you could go up to his desk and get one to solve, and we all did. His were this type. I never thought I'd see one again, thanks.

supro-
it's outstanding for you to bring this to the table. i did a lot of tangrams as a kid...
i'm gonna try the chain and rattle!
too cool.

I am just trying to find things to do when I Retire in March

Anyway you can not do the cube at 70 degrees
you would need a 20 degree dovetail cutter
they don't make them [ Google it ]
you can get 14 and 18 degree cutters
14 gives you 76 degrees
18 gives you 72 degrees

I am making them with a straight board thru the router table then cut the ends off 45 degree and make the box

That's what I did too. Much safer. But the wood grain direction gives it away. It's not obvious with small tight grain such as maple, but any wood with a distinctive straight grain pattern such as walnut or oak will give a big clue to how it's put together.

I AM THINKING LIKE THIS

WHAT CUTTER DID YOU USE



The one I saw had a magnet in it
the guy hit it and then you could get it apart

I am getting one of these and try it on my drill press



I got to buy all the tools I need before I retire

I also need a set of tubes for the 5E3 amp I will build

Please don't tell the miss's

I just used a standard 1/4" carbide dovetail bit. I don't know what the cutting angle is. I used a fence to plow one DT groove then flipped the piece to plow a second grove. Then I moved the fence a little to widen the two grooves to about 1/2" (don't recall the exact width). The mating piece was cut in a similar manner, but I 'snuck up' on the exact dimensions by moving the fence slightly and trying a test fit. It took several adjustments to get it right and tight.

[sluckey]

Thought I'd post a pic of my block to show you how the grain gives the secret away if you build it like I did. The grain runs diagonally across the block which is the same direction as the sliding dovetail groove. Experienced woodworkers will pick up on this pretty quick. Non woodworkers may never figure it out. Many wont even 'get it'!

My block is glued together so you wont get a clue by twisting or pushing on it.

That's what I was thinking
Why would you need an odd angled bit?

The combo of one right side up and one upside down should work or am I thinking goofy.

Since you don't care about wood grain
How about white and black HDPE plastic (cutting board material)

I use both colors in my shop and I love the material.
It machines very cleanly and cuts like butter on my CNC.

Any ole dovetail bit will work.

You gotta care about wood grain. It's a woodworking project.   

That plastic material would make it more of a challenge to solve. Got some in 3/4" thickness?

I almost built a jig to use on the router table so you could run the piece thru on a 45 degree angle, but decided that I only wanted one puzzle.

[EL34]

I have not found a place that has both black and white.

I have 3/4" black sheets here.
It is available from 1/32" all the way to 5" thick from McMaster

The white I get from a different place and they only have 1/2" thick, used for cutting boards.
But I have glued 1/2" sheets together to make 1" thick sheets and it works great.

Hi Supro:  That vice looks a lot like the one in the Enco catalog. If it's the import be careful I got one of the cheapie chinee jobs and the threads have a lot more slop than advertised- and you can't index them fer shize. No repeatability. They're ok for non-precision stuff like chassis holes, but not much else. I got it with a Delta drill press with an 18" table, catalog said "made in USA" the unit said made in china. If I had been a little less desparate at the time I'd have returned it being as it was 900 plus shipping.

What is not made in China today  

I know a Gibson Guitar  

And Gerald Weber Amps

Yeah, you may need to tighten up the gibs and then buy two cheapie magbase dial indicators (plunge type) set on the two axis and watch them - certainly ignore the crank dial with all the backlash.  Don't forget to lock the axis you are not using.  I bigger concern might be your drill press.  Unless you have a true mill or an old 1200lb cast iron drill press head, it may rattle to death.  Lock the quill tight all the way up and set your depth with the table.  Take it slow and hope for the best.  Or buy a router!

I am going to make this sawmill

http://www.procutportablesawmills.com/pictures.html

I need to make some slots in steel brackets

I retire March 1st got to something to stay out of my wife's hair

I noticed from the pole not many of us 63 to 69

I have my ash wood cut in 8 foot logs

I want to make some lap steel guitars from it

The vice is on it's way from Amazon.com
I bet I get it Monday

[Frankenamp]

Brutal! Somebody's gonna be a busy beaver!

[supro66]

Here is one that has a magnet lock on it

need to know how to open it
