I Broke the Lathe (Well, Maybe)

I was trying to create one of the gear arbors for a gear depth gauge tool.  I faced the brass, then drilled with a #43 drill bit for the needle underneath approximately 3/4" in depth, then turned about 3/4" of the outside to a half inch diameter.  I threw the home-made knurling tool in place, and tried my hand at knurling :

It worked great, but when I tried to clean the lathe, I realized it had broken (whether that is me or a previous owner) :

Now I need to replace the cross slide.
