Did you make the mag chuck you just got?
Seriously though, do you have an equivalent to McMaster-Carr in the UK?
If not, I’m sorry. They have dozens of balls in various sizes and different materials. All available at your door the next day. When you buy materials from them you get a certificate (traceable) so you know what spec it conforms to. If you order the wrong thing they will take it back gracefully.
It’s like living in the America I grew up in, where companies care about their customers and try their very best to make sure you are pleased with your purchase.
I have some Delrin balls I bought a while back from McMaster. Not sure what I’ll do with them but when I need them I’ll have them available. If they’re the wrong material, or slightly off size I’ll go online and have exactly what I need the next day.
Now, that’s what I call a supplier….
