[Elecraft] Solder fume extractor recommendation solicited

[Alan D. Wilcox]

I miss building the big boat anchors ... so when I needed a fume 
extractor, I thought to build it myself. The store-bought models are 
nice, but it's more fun this way!

These images are part of a web page that's not yet built, but since the 
issue is here and now ... these are links to the images:

What is it?
A trip to Lowe's got me 3" flex pipe about 3' long, and elbow at the end 
to point at my soldering project, and a expansion from 3" to 4" to bolt 
onto a box. The box is heavy plastic about 7x10x4" from K-Mart. Old 110V 
muffin fan that I had in the junk box. The air goes out of the box via 
activated carbon filter (less than $5) that's used on the typical 
extractors you can purchase.

The fan box is on top of some foam to cut down conducted vibration 
noise. I put some foam in the box to make quieter. When running, the 
primary noise is the movement of fumes into the pipe.

Not pretty, but it works!

73, Alan
