Reading some of the threads today made me think about dip tubes. Has anyone tried using something like:
with something like:
screwed on the inside as your tube? Assuming you measured your height correctly, you ought to be able to get it perpendicular with the bottom of the kettle.

1 - Would tightening the threads be enough to get an air tight seal, or would you need something else on the threads (such as tape)?
2 - Is the 90 degree angle too much for the siphon?
