No problem at all. I this year got my BS4872 certification & welder approval, and haven't even picked up a torch since doing it. That was 2 years of my time at night school aswell, but still I've got my little bit of paper to say I can do it. I don't suppose that it's a bad thing for a 60 year old.
 
I second Alan's request for more information on welding Aluminum with acetylene/oxygen. What filler rod do you use? I'm guessing aluminum? Do you create fillets before welding and fill, or butt weld? What type and size of torch tip are you using?
Thank you in advance.
