Steampunk(ish) Sight Glass

So today i made this little sight glass. It doesn't do anything really. But looks nice. You can use it for what ever you want. I geuss you can call it steampunkish.
Tools needed:
Small gas torch for copper soldering
solder
dremel with reinforced cutting wheel

parts:
15mm copper tube
12mmx10cm test tube
15mm end cap
90degree 15mm bend
5mm led
resistor
wire
hot glue and super glue

First you need to cut a 13cm of pipe.
Mark were you want to cut out the hole.

First of all be careful. The dremel is a power tool and can harm you. you need safety glasses. Small pieces of copper will fly around.

Cut along the lines.

To make the rond edges, make a series of small cuts. Then take some pliers and break them out. Get some sand paper and sand it. Take all the sharp edges off.

Solder the pieces together. Let it cool down and insert the test tube. Glue the end cap on your pipe and you are done. I hot glued an led in the bottom end. So it has a nice red glow to it.
