is it possible to increase the heat output of the burner by connecting two low-pressure supplies in parallel via a T-piece like this one? The primary factor is gas pressure at the tee. If the gas pressure drop from the low pressure regulator to the tee is negligible and the first tank & low pressure regulator is able to supply enough gas to ...

No, connecting two tanks together will not double the flow. The regulators fitted to tanks limit the pressure and flow rate so all you do is double the amount of gas the burner has available ie doubles the time of use. Do NOT interfere with the regulators. There are automatic change over systems that have both tanks connected and it switches over when one ...

I found an article that discusses the heat treatment of 6082: http://www.journalamme.org/papers_vol32_2/3224.pdf In the interest of having a standalone answer, here's a summary: You'll be able to recover quite a lot of strength by aging between 130 C and 190 C. The authors recommend treating at 190 C for 6 hours. Some overaging will occur at 190 if you ...

No. The regulator itself will see to that. It's around 30 millibars - 3/100 0f a Bar. The pressure inside a gas cylinder is around 10 Bars - 3,000 times that of what gets into your stove! It wouldn't matter if you had ten cylinders all feeding the regulator, it could still only deliver that 30 millibars to the stove. The only way to get more gas, therefore ...

Brazing process uses a filler metal with a lower melting temperature so the base metals are not melted ( as in welding). I guess soldering means the filler has a much lower melting temperature.

The most versatile brazing setup is oxy/fuel. Here the main hardware is a mixer head with interchangeable nozzle and hoses/regulators for oxygen and fuel. You can use either disposable gas bottles or larger industrial type rental bottles, which is best really depends on how much gas you are likely to use. This sort of setup gives a high flame temperature ...

It looks like the element itself sits inside a casting (presumably the mag/aluminium alloy) which itself sits on a disk of the same material which is screwed to the stainless base. It's not entirely clear is the screws in the picture are holding the element housing to the base or are there for some other purpose, but that is certainly one way to do it. ...

Aluminium reacts strongly with the oxygen in the air to form a thin stable layer of aluminium oxide which covers the surface and stops any further reaction. You have to remove this oxide layer, by wire brushing, before you can braze the metal. Aluminium is a soft metal, and the wire brushing will inevitably scratch and damage the metal surface. This is a ...

While brazing can be useful for ad-hoc repairs of aluminium AC TIG or MIG welding is vastly preferable for structural applications and in the long run is likely to be less hassle than re heat treating it. The advantage of TIG welding in this context is twofold: a) you can use filler metal which is as strong or stronger than the base metal and with an alloy ...
