You now should have enough of a foundation to begin your metalworking journey. However, before we start talking about next steps in this process, let's take a moment to finish making the teleidoscope.
To begin, apply contact cement around the edge of the aluminum tube that was left uncut, and the outer edge of the plastic washer.
Wait until the contact cement has dried to a tacky consistency, and then firmly press the two together.
Next, peel the protective coating off the lens and drop it into the tube.
Peel the protective coating off of the front-surface mirrors.
Form a triangle with the front surface sides facing, and then wrap a piece of packing tape around the center of the assembly.
Slide the mirror assembly into the tube. It should be a very tight fit, but do not force it in. Just wiggle it very gently until it slides in freely on its own.
Drop the crystal ball into the top of the tube.
Finally, insert the set screws one half-turn at a time. In other words, turn one
in a half turn, then the next, and then the next. Keep doing this until
the ball is firmly held in place in the center of the tube. If you do one screw at a time, the first screw will push the ball off center.
Do not tighten them too tightly or you might damage the ball.
Now that you have made it, it's time to play with your cool new toy.
These also make great gifts!
As mentioned, you can also easily convert your teleidoscope to a kaleidoscope by getting some clear plastic 5 gram cylindrical jars.
Fill them with whatever you like, and then insert them into the tube in place of the crystal ball. I filled one of mine with electronics components.
Step 8: Now What?
You have just scratched the surface of metalworking. There are still so many more things to learn.
Some possible avenues forward include welding, machining, and advanced finishing techniques like powder coating.
