I knew you could do it, first-chevalier. That's really great. I've found a knew way, yet more expensive, for those makeshift bulkheads. It seems to work a smidge better. If you run out and grab a couple rubber washers of sufficient size that there is rubber around the edges, you can cut a hole out in them and place them on each side of the glass. Here are some pictures.
First, take the male threaded piece that you will be using and use it as a guide to mark how wide the hole will need to be
Though the rubber washers are black, the ink from a permanent marker is darker and shiny
Then, take a razor blade or x-acto knife and trim out the middle.
Always make sure that you have a solid fit. Make sure that the hole that you cut isn't too large or too small.
When the washers are all cut out to your liking, add the male piece first.
Add the other washer
And lastly, add the female end. Twist down snuggly, but don't over crank it. It should work like a champ.
