How to Make an Identity Disc Prop (Tron: Legacy)

It's not a perfect replica, but for people who don't want to buy the deluxe Light Disc or don't have access to milling or plastic casting, this is an easy way to make a Light Disc.

My version is not exactly how it is in the movie. It's smaller and the inner circles are supposed to connect. It is also supposed to be ~7cm thick. Mine is ~12cm.

Feel free to interpret the measurements.

My interpretation: 25cm diameter, 7cm thick, 7cm ring diameter.

I was limited in foamcore, so I made mine smaller.

Step 2: Cut out the circles

Cut out a circle. Cut out the inner part of the circle to form two rings. Cut out a portion of each ring.

Bend both rings inwards. The two open ends will bend together to form a sloped ring.

Repeat.

Step 4: Stuff

Stuff ring halves with newspaper (I used regular paper) to add structure and mass. Then tape the two rings together.

Step 5: Optional: Inner connection

If your Lightdisc is like the movie version, you don't have to do this. Unfortunatly, I made this after seeing Tron once, so I made the mistake of not having the inner rings connect.

I you did it like me, connect the inner rings with a peice of foamcore to fit the gap. Add more newspaper as you go along.

Step 6: Sanding

You probably won`t get a flush edge where the two outer rings meet. So sand the crap out pf them until they are.

u dont like imperfect things yet you misspell your own name, good job C.L.U. (PS. thats how you spell C.L.U.)
Maybe you could paint on a layer of glow in the dark paint over the blue?
