custom fittings for Blichmann sight glasses and thermometers

With 1-1/2" triclamp style butt weld ferrules added to the walls of the kettles at every hole, I needed some custom fittings to get the thermometers and sight glasses attached to the kettles again:

• for the thermometers, a standard 1-1/2" TC endcap drilled/tapped for 1/2-20 thread (this was simple)
• for the sight glasses, a custom machined fitting (all one piece, no welding, drawing here), drilled and tapped for a straight thread that is a little tighter than 1/4" npt (I didn't make a note of the specific thread, but can find out if someone really wants to know)

Since these are threaded, they're not sanitary, but the benefit is the ease with which they can be removed for thorough cleaning and sanitization, and then reattached (as opposed to having to having to practically crawl inside the kettles to remove/reattach the originals. Later, I'll post about the fittings for the main ports and the return ports because I'm actually still working on those.
