looking for a spindle for a hardinge cataract toolroom lathe

I recently picked up a hardinge QC lathe. I finally got the time to use it today, but after a few cuts, the chucks wouldn't go on anymore. Looking closely at the spindle it seems there is a crack running the entire distance.

It seems like the spindle is cracked since this is a weird way to design something so important. If anyone w/ a hardinge QC toolroom could check theirs I'd appreciate it.

I'm also looking for backgears if anyone has them.

ARGH!
