When I plan and design my overlays, I first take a piece of paper, wrap it around the material I'll but cutting, and tape it. Then, I remove the paper, fold it flat (lengthwise), and then begin drawing. I'll usually have a rough plan sketched out before this.
Trim the paper to length, and draw away.
Anyway, I draw just on one 1/2, and then I slide the paper back on to have a rough look. Some lines usually need to be adjusted, one way or another.
When you have a design you like, cut it out. I use scissors and a knife.
Then, slide the template back onto the metal shell, and trace with a sharpie. Be careful, as sharpies are supposedly permament, but it can actually be rubbed of with some general handling.
Once the layout is finished, carefully remove the template (to save as reference for later).
Now, the messy part. Dig out the all mighty Dremel, and go to work. Depending on the lines designed in, you may prefer to drill corner pilot holes with a drill first, for sharp curves. I usually use a regular cutting disc. To expand the tighter corners, I also use a Tungsten Carbide Cutting bit (Dremel bit #9901).

Make sure you have a firm grip on the dremel, as it is really easy for it to skip, especially on fine work.
When you are finished, use at least 2 sand paper sheets, as Loreen stated above, for finished the edges.
Well, I think that about covers what I wanted to say, to help you out.
Good luck.
EDIT IN: One thing I forgot to mention. When using the regular brass (chrome or plain) sink pipes for overlays, keep in mind that the pipe is actually under pressure, and will spring open, if too much material is removed around the circumferance. It wants to flatten out. So, don't try to get cutouts too long and fancy, or it won't sit flush against the base hilt.
You'll see what I mean, if you cut a small ring of pipe off one end, and then cut through the ring; it'll spring open.

You should be just fine using what u have. But if you want to make extra sure everything will be ok you can use the 4AAA battery holder and solder a wire in place of one of the batteries. This way your skipping over that battery slot and just using 3AAA batteries. Im using this method on my newest saber, and retrofitting an old one the same way. Really the LEDs can handle 4AAA's but soldering that wire will guarantee that u dont overdrive the LED, thereby saving u some wear and tear.
Hope this helped,
