Step 4Prep the shell - Part 2
GLUE THE BLADE
We're gluing the blade to the top half of the Disc - this is the half with the clear C-ring. Do not glue it to the bottom!
Because we've removed the guides and tabs that helped put the blade in place - I recommend putting the blade back in. Once you've done that - make sure two halves can close fully. Once you've checked to make sure you've inserted the blade correctly, remove the bottom half and run a bead of superglue around the inside of the blade where it meets the black plastic. We're mostly doing this so that it will stay in place while we're fitting in our electronics - don't go crazy with the glue.
MARKING THE DISC
In order to make the new disc as movie-accurate as possible, we're placing 16 leds in the inner ring (convenient since the LED chip we're using breaks leds into segments of 8). The remaining 48 leds will go on the outer ring.
I found that the inner ring is about 40cm and we need 15 breaks - leaving 2 2/3 cm between each LED. I mostly eyeballed this section, but used a measuring tap used for clothing measurements to make things a little easier.
The outer ring is much simpler. We need to separate it into 48 segments. There are already 6 posts evenly spaced around the disc. Using your sharpie, make a large mark at each of these posts (6 marks). Then add a large mark in the middle of each post (12 marks). Then make a smaller mark between each of the large marks (24 marks). Then add a smaller mark between all of the marks (48 marks!).
OPENINGS FOR THE INNER LEDS
On the inside of the inner ring, you'll need to make openings in the black plastic so that each LED can shine through. I like to use an engraving tip on my dremel to make these openings. A small sanding drum would probably work as well.
Using one of your LEDs, make sure you have a large enough opening so that the LED will shine through at each location.
