Nice setup.  It's fun to see it develop.
The video's and pix are excellent.

Now, as to your mod on the lower sightglass
fitting.  Did you just drill a hole, tap it
to your needs, and fit the parts?  I'm curious
as to how deeply into the sightglass fitting
the tube goes.  Doing it is a great idea and
I thank you for the close-ups.

Good work,
Wayne
