My tailstock spindle has a crack

[Fred]

Hi everyone, 

I noticed there a crack the collet end of the tailstock spindle and when I tighten the collet the crack gets bigger and renders the tailstock useless, I searched for a replacement but I couldnt find any, do you think it can be made and how much would I have to pay approximately?

Thanks a lot

Make a steel ring and shrink it over the end with the crack. It should allow you to use it until you source another.
