I am trying to find out how much I would need to spend to get a lathe that would allow me to turn down my own air rifle barrels?

I don't want to spend a fortune as I don't have a regular need for steel turning. I would be happy to dip my toe with with a bench lathe but most of the ones I have seen seem too small to turn a 22" barrel or they have plastic gears that don't do so well with steel.


So... are there any hobby-level options for turning a 5/8" x 22" steel rifle barrel?

I don't mind if I have to work slowly as it's just for a hobby. I just want to know that it's possible for me to get there eventually...
