More random machining

Seems like there's always more machining to do...
Wing endplates for the moving element + one that I messed up in the background

We have a special castle nut tool that was made to allow us to tighten and loosen the castle nuts that hold the spindle in.  I made a new castle nut tool; the old one was aluminum and, well, it broke.  This one is steel and should be a lot stronger.  Oh, and machining steel with a cheap Chinese HSS bit = bit going dull half way through the operation and having to replace it.

Machining a new castle nut tool
It uses a standard 1 in wrench this time instead of some random metric size that you can't actually get a socket for
