Making loaded cheating dice
Back in the 1980s I experimented with making a "loaded die", one that had a tendency to roll high numbers. I made this one out of a large-ish wooden die, which I split open with a chisel, hollowed out, weighted on one side, and glued back together.
It's not guaranteed to roll a 6, but it has a much higher probability of landing on a high number than a low number. I showed it to some friends I played RISK with, and the first number I rilled with it was a 2. My friends didn't believe the die was loaded. I should have just gone ahead and used it in the game!
You can see the split line, especially where I applied the chisel because the wedge of the chisel compressed the surrounding fibers before the wood split.
Then used a brad-point drill bit to start hollowing it out. But with the long brad point on the drill, I couldn't drill too deep without the brad coming going through. So I used a very short drill (a machinist's center drill) to mostly flatten the bottom of the drill hole.
I used a carving knife to cut away the burrs from drilling the holes so the two halves would mate properly.
This hole is a bit off-center in order to also be near the 2 and 3. This way the die also has a tendency to roll some of the other high numbers.
I ended up making a few more, experimenting with different ways of splitting it. Splitting it with a knife (tapping the knife in with a mallet) ended up working better. The narrow bevel of the knife applies pressure more evenly, making less of a chisel line and less damage to the faces than my splitting it in the vise method. So if you want to make a cheating die, I'd recommend just splitting it with a knife.
