901 atomizer disassembly

[mogur]

Nothing new here, just another disassembly pictorial, since I fried this atomizer and wanted to explore it's design.

The whole ball of wax...


One layer of foamy metal removed...

Input end of the atomizer...

The naked truth...

The business end...

What the hell is this foamy metal ? ? ?

Doesn't look like a metal weave and it certainly isn't steel wool...

This is the best I could do with the coil, don't have a microscope and the camera doesn't even have macro...

One more try with an eye loupe held in front of the lens...

I guess this is why it is called a four hole atomizer, since it has five (plus two for the wires)...

I'll cad a drawing of this atomizer. Even though there are a ton of drawings already out there, they almost always leave out the functional parts like the metal foam.

Thanks for your efforts. This goes along ways in helping even us non-modders understand how to use these things!

agreed - where DOES this metal "foam" come from?

mogur - a nice set of pics, well done

Noticed that the coil is not well spaced out in this instance.

Where was the break?

Dead in the middle, one loop burned through on both ends, the total length was 1.2 inches, .004 nichrome, 38ga.

I have the whole thing cadded and dimensioned, but I don't have a good way to post it at decent resolution. Here's the first page, but I have to screen capture 15 times and paste into a paint program. Anyway, I'll figure it out.

Roswell N.M. 1947. It was found at the crashsite
of an U.F.O. and since turned into the mesh that
we all love/hate...sooooooo muuuuuuuch.

Just my lame attempt to label these parts. In this case, that little plastic part has a funnel shaped orfice that speeds up the air as it is drawn through through the passage. When you neck down an airflow, it is called a venturi. Venturis are used in gas engine carburetors to suck the the liquid gas into the air stream and vaporize the liquid before combustion.

Bevelling the air inlet hole can reduce the hiss/whistle noise (a tip by ***). Haven't tried it yet but sounds like it would work.

If an auto., be caeful not to enlarge the hole.
