Sight Glass
I wanted a way to monitor and estimate the flow of oil into the centrifuge. I ordered a sight glass from McMaster-Carr for less than $15. But when I hooked it up I discovered the oil flowed down one side rather than an even stream down the center. So I turned down some brass and made a nozzle extension that works great.
The sight glass installed easily atop of the feed tube. Unfortunately, the oil flowed down one side rather than as a stream down the center. Upon inspection it appears the oil is hitting the o-ring for the glass window. The ID of the brass elbow is 0.3125. A piece of copper tubing would be idea but everything I had on hand was the wrong size. So I turned a tube extension from a scrap of brass. It only took a few minutes. Here I'm parting off the tube. These are the parts after cleaning in preparation to be fluxed and soldered. The fit is a snug sliding fit which should hold it in place during soldering.

The parts soldered easily. I just need to clean off the flux. Feed tube assembly with the modified fitting and sight glass. The modified sight glass assembly is working great. It's now very easy to visually monitor the flow into the centrifuge.
