I just finished this one the other day. after owning the original, this one sounds just like it but is a LOT smaller in an etched 125B:

Very nice!  Excellent etch and it looks great with the polished enclosure.

[m-Kresol]

I agree, that one is flawless

[Stomptown]

Beautiful etch!

[gordo]

That's etched??!!  You guys are just taking this stuff to the next level!

Ooo an LTC1144, fancy!

[Drew Hallenbeck]

WOW! Awesome looking build!
Your etches are amazing. I've been getting some pretty decent results but still not quite on that level.
Any chance you could share a quick run-down on your process?
Prep, masking technique, etchant used, time/temp, etc....
Would be greatly appreciated!

That is a pretty flawless etch. Looks fantastic and I'd bet it sounds nice too.

[Boba7]

So great!!
I wanna build one now!
Looks fantastic, really.

That's a killer etch. Did you etch the polished enclosure or polish it after the etch?  I've been wanting to do something this clean for a while.

This looks amazing. If that's an etch, it's one of the cleanest I've ever seen.

Perfection!

thanks. first I sand the enclosure with a Makita orbital sander (150, 220 and 320 grits), then I block the face with 400 grit wet. then I etch it with acid magic, then I block wet sand the face with 600, 800, 2000 and finally with 12000 micro mesh. the block sanded 12K paper results with a polished finish.

Thanks for sharing.
Do you do your masking with toner transfer? (laser printer/glossy paper, what paper do you use?)
Also, how long do you let them etch? Do you do anything for agitation? What about temperature?
I don't mean to nag, I just really want to find a better method for clean etching. And yours sir are perfection!

Killer response.  I think I need to get some sort of powered sander to get the imperfections out.  Right now everything is done by hand.

Also, what's acid magic?  I just ran out of my bottle of ferric acid and am interested to try something that doesn't stain everything in my basement.
