I am intrigued that you do "brazing using compressed air". Persons used to braze on acoke bed stirred along with air from a vacuum cleaner or suchlike but what do you do please?
Bob,
I have just finished building a large copper sculpture of a dragon. I needed a lot of heat for the brazing, without resorting to the use of oxygen. I built myself a blowtorch from an adapted oxy-acetylene torch and ran it on propane and compressed air direct from the compressor. I made a couple of different sizes, both of which worked well. Flashback arrestors were fitted to both hoses.
Now that the dragon is completed, I can actually get on with my Austin Seven build, the engine being the first main thing to be touched.
Regards,
Jamie.
