Nice!

That brazing kit looks good, did you go for oxy propane in the end? Would like to know how long the o2 lasts you. I do most of my brazing at work, but I want to start doing more at home. I hope you have a power file, it will make clean up 10 times faster!

It's a 9 litre oxygen tank, so it should last a few hours, but just little cans of propylene/propane mix, so a bit hotter than just propane, but probably don't last long (the website reckoned 2 hours with a number 7 nozzle). I still had some problems where there was a lot of thick headtube and reinforcing gussets, so have bought some bigger nozzles. Just waiting for some child free / non-dark outside time. Seems to be a rare thing nowadays.

I don't have a power file! Is there one you would recommend?
