Step 4Put it together
This really just consists of first punching a hole EXACTLY in the centre of each rotor with the thumb tack, and then threading them all together with the split pin.
Notice I said EXACTLY the centre? That's because it matters. If you put it off centre, then when you spin your rotors around all sorts of non-linear things will happen, and basically you will end up in a lot of trouble. If necessary, re-print and make the rotors.
As I said before, the thumb tack is the best way to make this hole, because it will be round. If you use the split pin to push through, it will make a slot, and when it rounds out, it will almost certainly not end up in the middle.
You can get little biddy split pins from craft shops. Here in Australia, office works has them for about A$5 for 100 (that's about US$4.50 today, but with the way the Aussie dollar is climbing against the green-back, it could end up being US$10 by the end of the 2009). I expect if you are in the USA you can get them at Spatula City, WalMart or somewhere like that.
Finally, when you are all done, slip the paper clip over the whole thing, with the smaller side over the head of the split pin. You might need to trim a little off the outer rotor if it won't fit.
The paper clip provides a bit of positive pressure on the rotors, thus increasing their friction. This makes it easier to turn one rotor without them all turning.
If all goes well, yours will look something like mine.

I like the spatulas so much, I bought the company!
