Silver wire embedded goose egg shell

The first trial

0.2mm silver wire.

Brilliant!
A work of great care and patience I imagine to get the silver wire embedded without breaking the egg?
And what glue to hold it in place?

Cheers
Roger

Thx Roger,I am wonder that the egg shell does not break

Look like goose egg shell is not that brittle.And I used instant glue to hold the silver wire.

Thank you for posting all of this great artwork. Like many others, I am amazed.

Looking back at the egg that you drilled with so many holes, you mentioned that there were some challenges with holding tolerances. Do you think that the process of drilling the holes might have shifted the egg's surface around vs the original scan?

My wife is not usually that interested in CNC, but I am definitely going to show her this thread.

Thx harryn,i guess the egg shell is abrasive. it makes the drill bit blunting quickly. and causes the wandering effect.and hope your wife like it

Thin delicate chicken eggs? OK, that is special.
You have the surface-following down to microns.
Wonderful!

Have you thought of using air-gauging with a small orifice? Since the probe does not touch the surface you could actually spin the egg while measuring. Hum ... now try getting the data back into Mach. This could be tricky. ModBus might work. Some experiment needed.
With the speed of air sensing you could make multiple scans of the surface and average.

Cheers

Air gauging method is a bit too sophisticated for me

Right now, it took me 15 minutes for 1500 points. It is quite OK for me already.

That fast? Fair enough: you don't need the complexities of air gauging.

I hope you post more details about your process. Very inspiring!

Here a bit detail of it.

[QUOTE=uvvvvw;1817238]Thx Victor.

how you can remove the ready egg?
[Just melting the glue]

what diameter that tool you are using?
[For relief engraving -- 0.2mm 30 degrees flat tip engraving tool]
[For hollow out -- 0.6mm PCB rout bit][/QUOT
Hi I like this machine and I'd like to buy it .would you tell me more details about this? How much it costs and which country is this from ?or which Brand?
