[TheForge] making blow tubes

[Peter Fels & Phoebe Palmer]

Ah, that kind of blow tube!
There's a jeweler's device used with an alcohol lamp or similar flame. 
It's a light tapered tube with a dinky orifice at the small end, held in 
the lips and supplied with air by the cheeks used as bellows. The jet of 
air is blown through the flame projecting a tiny tongue of flame for 
spot heating..silver soldering.
