Blow down valve

Simple Blowdown

[File:David - DSCN1354 - reduced 5.jpg David (Builder01) posted the following on Chaski.org]:

Here's the drawing and photos of the blowdown valve I made for my loco. I made the body from hex so I could make sure it was driven into the bushing on the boiler tightly. The position for the discharge pipe was marked after the body was screwed into the bushing. Then removed, and tapped for the discharge pipe.
