Here is the cliff notes version of the subject thread I started and wrote a lot about on VS. Brazing setup is a big subject and can’t adequacy be described in one post. For starters, don’t buy a brazing package because they don’t have what is ideal for making frames and probably have stuff you won’t use. Lets start with your fuel supply. A full BBQ tank of propane costs in my area about $50. A refill is $20. It will last many times longer than my big tank of acetylene. Most places don’t have regulations about having a BBQ because it is a popular activity. You will need a propane regulator that – if it has pressure gauges – will be available for under $100 at a welding supply store or online. You don’t need an oxygen regulator if you are using a concentrator. They don't have a pressure tank to regulate (or explode) so there should not be any worry about having one on the premises. They regulate the volume of oxygen in the line by a control knob on the concentrator.

The smaller 5-liter per minute oxygen concentrators are sufficient for most bicycle frame brazing. Look for used ones on Craigslist or the classifieds. They can go anywhere from $50 (if you are lucky) to $200 used. Reconditioned ones with a 3-year guarantee cost around $300. A Devilbiss brand already has a male size B brass outlet that a brazing hose can screw directly into.

Aircraft style of torch handles are light and work well for frame making. On Amazon a Uniweld 71 can be bought on average for about $70 (although I have seen them for $40). It is a Victor compatible torch. You will need a UN-J Victor (or clone) mixer/elbow to attach to the handle. On the end of the elbow are threads to accept different sizes of tips. Propane specific tips to match the Victor UN-J mixer/elbow are designated TEN. They come in different sizes but the most common sizes for making frames are TEN-2, TEN-3 and TEN – 4. If you are on a tight budget the size 3 will work for almost everything. The Gentec brand makes cheaper clones of Victor parts.

Propane requires T style rubber welding hoses. The R type should only be used with acetylene. TM Technologies makes a much lighter version of hose that makes the subtle brazing motions easier. Of course if you are ordering from them they have almost every part of the puzzle except the concentrator. For safety there should be a flashback arrestor between the hose and the propane regulator. For additional safety it is also wise to use check valves on the end of your torch handle. Of course by now you have blown your $200 budget.
