Ok, these are admittedly horrible pictures, but the lighting on my workbench is terrible.

The first shows the top view. You can see the large slot. The second shows a side view where you can see the second slot going all the way through the plate. It's currently occupied by a zip tie, but you get the point.

[edit] Just saw Travis' post. We too just use a nut buster, unless for some reason we need to reuse the pinion. In which case we use the plate. We also bent/broke the first plate we made.
