Nope. Not this time. I was expecting the same thing, but this one does look to have a worn tooth on the cogwheel. Incredible, because these damn things are made of some really tough stuff. I tried to drill a hole in one once, and every bit I had wouldn't make a dent. Steve Young told me you need a carbide bit to drill into them, because they are made of hardened steel. I thought I was drilling into Titanium!

You'll need a carbide bit to drill a hole in it.

Yeah, I did. You did eventually see the one that is obviously worn. I've never come across something like that before. Those ratchet wheels are made of tough stuff! In fact, I wasn't even trying to drill a completely new hole into one. I was trying to enlarge an existing hole in order to install a bolt and nut for the limit switches.
