Guys, thank you so much for the constructive comments
I didn't realise that 531 was not made anymore, but I'm sure the tutors will have everything worked out regarding suitable materials for a beginner. Im speaking to them this week hopefully after paying the last instalment today.
I love the look of both fillets and lugs and didn't really have a preference to learn one or the other. This course specialises in teaching fillet brazing and is located in my brothers home town (so I save on hotel bills!). I was a pretty good mig welder in my day, Im hoping one day I can have some decent fillet brazing skills too.
Thanks again!
