Step 4The Dial
2: Take some pieces which will be the part of the dial to hold in your fingers when turning it. I took the inner part of a wheel and a round 2x2 plate, but I can understand if you don't have the weel rim. Use similar lego pieces, there exist a lot of them like this, or other discs to use for the dial, so this shouldn't be a problem.
3: Join it all together.
dial design: print this with the size of 4,5x4,5 cm(or 1,77x1,77 inch) on hard paper.
4: Make a hole in the middle, so, that a black stave fits in.
5: Put some hobby glue on it, You can use just a very little bit if you're going to execute step 7 and 8 aswell. If you don't want to get a little glue on your lego, you can enclose this paper between the two holed discs, but then there's a chance that later on the paper will move, and the combination you've remembered doesn't work anymore.
6: Hold it for a moment as the glue dries.
7: For the best result, take six really small nails.(even these are a bit too big)
8: Press them through the paper, on the places of the disc's connection sticks' holes.
9: insert the dial into the first rotor, and carefully(because the first rotor isn't fully enclosed yet) test what your combination is. You should check this, because now you can see what happens with the rotors. In the next step we will build it in, so you can't see it anymore. If you disagree with the number, you can get the dial out, turn it it a quarter-revolution, and put it in again. Then repeat the test.
