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
