Want to braze?
It's cheap and easy. This is all you need for low-temperature brazing (aka silver soldering or hard soldering), and then you can do your own frame modifications at home! A plumber's Mapp Gas torch, some silver-solder flux and the precious silver brazing wire - which can all be had for around £50, then watch some YouTube tutorials to see how pro framebuilders do it. It ain't rocket science, and anyone should be able to pick up the skills quickly. The silver wire is expensive, granted. Easiest to use (lower temp and better flow) is 55% silver 1.5mm wire. The flat strip is 38% silver, which is cheaper and stronger, but has a higher melting temp. Learning to silver solder (and use a file!!!) means you can do all kinds of useful mods that a framebuilder would charge a fortune for. Go on, have a go - get modding!

Are all your brazing done by using this torch, even the structural cutout on the chainstay to accommodate the cassette wheel? Where's a good source for braze ons.
