Sight glass for fuel tanks etc

[RM-MN]

What's a "sink downer" ??? Guessing some American plumbing fitting as opposed to some truckie drug.

The common term for "sink downer" here is sink tailpiece.

Old movie projectors have a round piece of glass in front of the light bulb. They are made for the high temperature.

Io ho usato questo sistema, il tubo di vetro sul tornio con gomma nelle griffe
Poi col drimmel e lama al diamante con acqua, il tornio gira piano e il drimmel velocemente, sono riuscito a fare un cilindro di vetro con foro di scarico

Old gas engine oilers make good fuel tanks.

Now that is a neat idea. How long will it run on that oiler full? Bob

Lab glassware comes in all shapes and sizes, and doesn't cost much. All my sight glasses and oil reservoirs are made from cut down pyrex test tubes. they come in many sizes. My set up is as per the photo- dremel drill in the toolpost; the lathe rotates at a low reverse speed, with the bed covered. I use a diamond disc to cut, and then heat the finished piece to melt the sharp edges with a blowtorch.

As an interesting aside, chemists refer to the heating process as annealing!

Slightly off topic, but has anyone posted use of common household sink downers for tank main bodies? Nice thinwall brass 1.5" dia., various lengths, cheap and available. Nowadays unfortunately many of these are chrome plated.

Hi Canfly, yep i used the down pipe for my tank in the upshur engine. it was chrome coated brass. cost me about 7.00 US if i remember right. probably could have gotten 2 tanks out of it. it worked great. just used some emory cloth to sand the chrome coat off of the brass and everything soldered up just fine

Yes I recently used a boat, aka naval sink drain as a gas tank. Worked great. No plating as it was Naval / ship related.

I've heard people refer to boats as a naval sink drain for money ...

I sandwich a few pieces of Polycarbonate between a couple pieces of plywood and pinch in lathe with tail stock and turn them to dia that I need.
