The great thing is that they are basically surplus scrap and if you screw up the slot cutting, you're no worse off. This isn't something I would go through for a polycarbonate tubing based sight glass but it's absolutely mandatory for those using pyrex glass.
I just fabricated mine tonight. Not a dip tube, but another piece of thin tubing I had laying around.
My thoughts on the target level markers (zip ties) was to grab a few 1/2" od ORings and have them available for marking targets. Now if I could only find singles in different colors, that would be cool. I think I'm going to paint the inside of the tube and just mark on the back the quart levels...Now I need to figure out what color. It'll be my HLT, so I'm trying to make water more visible...

Could you use a black permenant marker to mark the lines on the back of the tube and then paint over them with white paint? That way, you should be able to see black on white contrast.
