I need to harden a shaft that a needle roller bearing is going to run on. I have seen some things here and there that can be used to case harden low carbon steel at home (funny powders etc...), but most have been adverts from back in the day (like long before I was around). Does anyone know of any of these 'chemicals'/'mixtures' that can be bought in the 21st century and how effective they are???
Am i better off just getting someone experienced to do it for me?
Thanks
Warren
