what kind of scale of operation is silver brazing with say one of those OxyTurbo kits?
i.e. could i do it in a reasonably large flat kitchen with a vice on the table, or does it require more of a workshop environment?
To heat up the tubes sufficiently to get the silver to flow, while not as hot as is needed for brass, you do need quite a high temperature and I most certainly wouldn't want to do it in my kitchen. The vise must also be firmly affixed which is another thing that I wouldn't want to subject my kitchen table to.
For the rest, you could indeed get by with what you are describing. Let me only say that the simple fact that you are asking such a question makes me think that you need to think teh matter over a bit more before you go ahead...
