Equipment for brazing?

[noel shelleyParticipant @noelshelley55608]

Jason has illustrated very well the capiliary action of brazing and it's small fillet that makes a fabrication both strong and gives the immpesssion of being a casting ! The equipment needed is modest and one can soon learn the skill. Tig, MIG or MMA would not be able to produce this part as well , it would take much longer to learn the skill and the investment in equipment more costly. It is a case of horses for courses. It very much depends on what you need to make, your skills, and the equipment to hand. For me Jasons part I would cast, but thats because I have the gear Etc. Noel.

PS I also have oxy-propane, air- propane, MIG, TIG and MMA.

PPS, Jason is the cooling water tank stainless ?

No just a steel fabrication, should not be much worse than cast iron like the original. I usually slosh something around inside to as a bit of protection. Three is a cast iron sleeve that passes right through to form the cylinder Loctited in at each end which is the usual way that most of these models from castings are done as it makes for a much simpler core to form the hollow inside rather than having to have it wrap around a cored cylinder to form the jacket

These models can often be run without water if they are just ticking over for short display runs as they only tend to get hot when being worked or run for long periods and in the case of the hit & miss ones you are pumping cold air in and out of the cylinder during the miss strokes which helps with cooling.

Hi, in my last day job I once had to repair part of a Go-cart chassis, It was a tubular frame and a couple of small struts had broken away from a main tube where it joined another one. When I clean the area of paint, the struts and the two tubes were MIG brazed together. Well, the firm had no equipment for doing MIG brazing, and when I told the supervisor about it, I was told to do it with Oxy-acetylene, so I said it won't look as good as it was done before, and it would show up against the existing well brazed part. He just said not to worry about it and just do it, so I did. Whoever did the brazing on it when it was made, was certainly good at his job.

Regards Nick.
