Ok so I’ve made a few changes, upgrades really, to the burner since my last post. I’ve pretty much revamped the whole thing hence the new instructable.
The basic concept behind this burner was to make the nozzle interchangeable so that the unit could work as both a forge burner and a foundry burner.
Essentially the unit breaks down into three parts: the fan mount (I used the one from my other burner
), the mixing chamber, and the nozzle. When connecting all the peace be sure to use pipe dope or plumbers tape with the exception of the nozzle and fan attachment areas, as these will see the most ware from change out. if you choose to make the connection more permanent go ahead and use the dope or the tape.
