its the best thing I've found so far (as my little broz christmas gift) but it costs $90! Can we  make something clever like  this at home?

If you did have the skill and facility to make this, it looks to me like some difficult MIG welding. If I had my new shed's wiring done i would definitely give something like this a shot. Welding the wire arms does seem pretty hard to me.

Mig welding is the easy part, the whole thing is just tack welded together, as for the wire, its quite thick wire so it shouldn't burn off. For the hands, set the pieces flat on a block of copper and give it a good squirt on a moderate heat. The weld will not stick the the copper, thus you dont have to worry about burn through.

The rest of the piece however is a bit more challenging.

The bottom discs are laser cut with a bearing in the middle, the top disc has also been laser etched to give the lettering.
The heads have been die pressed to get the shape, and then laser cut to get the teeth.
The eyes appear to have been die pressed also.

Short of having a die press and laser cutter, Try;

Metal door knobs - right size and shape, should be easy to file teeth into with a triangle file.
Press on axle caps (found on kids toys) for the eyes
ARC electrodes for the wire, right size, easy the bend, but not to thin.
Use a permanent marker to stencil the lettering on.

Happy welding.

The heads are bottle tops that look like they've been pressed out to get the teeth.

Bottletops far too small and the teeth don't go all the way around.
Head pieces are press formed from plate and laser cut, most likely with a 5 axis laser.

No way. If they aren't bottle tops, they're punched out, then pressed. No-one is going to use a 5 axis laser to make trinkets.

Definetly not bottle tops, and these arn't hand made trinkets, they are made in a production welding facility. Looking at other units they may be laser cut before being pressed. Very easy to use 5 axis machine for doing these as you can set up a production run to cut dozens in one go, or with a conveyor system, continuous cutting is very efficient. Cut would be less than 2 seconds each, and at $50 per unit, very cost effective.

I'm interested in seeing what system you think will cut that job in 2 seconds.

Try this.

This is a single part run on thicker material, but you get the idea.

Set the table (or conveyor) up with a jig that you can drop uncut parts onto, and you can cycle through continuously. Add to that the fact you only paying the staff in your 3rd world country manufacturing facility 20c per day and it gets very profitable very quickly.

I don't see you doing the teeth in that cycle time, even with that VERY nice machine.

For 20c a day, it could be guys with files...

Could be guys with files, but with a cutting feed rate for 1mm mild steel of up to 25 m/min (833mm/2sec - Give or take, its been a few years since i read the manual), that very nice machine will do a very nice job when set up properly.

No, I'm not talking out of my a@#$, I have cut sawblades and other similar items with THAT very very nice machine. It really is that quick.

Anyway, turns out its a bloke in utah,

If it didn't have to be metal, you could make the little beasties from ping pong balls cut in half, coathanger wire and beads. The base could be a bit harder, but all you really need are a nice free-spinning bearing (skateboard wheel?) and a pen holder, or a cardboard tube and some thin wood sheet to make your own. You could then paint the whole thing with hammerite-style "metal effect" spray paint

I was looking at this again, and if you didn't NEED for it to be the exact same color, you could use copper as suggested by crapflinger, meaning you would only need a decently heavy duty soldering gun.

IF you needed the color, the whole thing "could" be dunked in the proper solution and electroplated with tin or a thin layer of silver that would then tarnish to about that shade.  The roughest part to make then would be the heads of the little guys, as they look "almost" like soda bottle caps (which would NOT be brass or copper).


WAIT !  I just had another idea:   you COULD (if you can make the individual parts)  lightly sand and polish the sections that will meet, so they are really flush, and then super glue them together.   If the parts are flush, it should hold for a long long time.   Otherwise,  Caitlinsdad has a good suggestion on this too.

BTW: the two "platters" could be made from two OLD HD platters, with a ball bearing and race between them.

i would say if you don't go the copper flashing route, you could make it out of simpler materials like foam core or MDF

if you do the foam core, you make the basic geometric shapes of the base, then cover everything in bondo (so that it will be more sturdy) then use spray paint to make the antiqued metal effects.

for the guys, some simple wire and some kind of spherical objects would get it done.

If you work with copper, such as using a copper measuring cup or cannister and copper roof flashing, you would be able to solder it together. Otherwise, JB-weld glue or epoxy to put together the metal parts. Good luck.

Welding works too for heavier metals and is more permanant

To copy that, you'll have to learn to weld.

Maybe better come up with a scrap-based sculpture glued together, and add a spinner-arrow to a disc on the side.
