Hey all,

I have nearly finished getting all of my equipment for my first AG but need to join some copper elbows and t-pieces together to finish the kettle. I have the flux and solder but no torch, but will be buying a nasa type burner from Gameco soon and wanted to know if this would be hot enough to solder with?

If not is there another method of joining copper pipe that can be used? :huh:

Cheers

Plenty hot enough although considering the heat of the flame and the conductivity of copper I would be holding the pipe with a pair of tongs. Given photo's that others have posted I imagine the NASA would be more than hot enough to hard braze with.

sounds like a perfect excuse to buy a blow torch - it really makes you feel like a man!

Also good for defrosting freezers hey Al? :D

Hmmmm... Can smell that acrid aroma of hairs a'burning on the arm now. :blink:

Think you will find that torches aren't overly-expensive.

You can buy those Bernzomatic propane torches for about $20, including a bottle and tip. I used one for soldering all my copper work in my brewery and another project ;). They will do it no worries.

Are you using lead free solder? Wort is acidic and cleans copper up nicely and no doubt will take a nice little proportion of lead from the solder. Up to you but you can get a brand of leadfree solder from bunnings called Aquasafe 100, it's a 90% tin, 10% Cu, Ag and Antimony. No cadmium either.

Most solder is 50% (labelled as 50/50) or 40% (60/40) lead. Also, make sure you wash the flux off well too, that stuffs not good for you either (ZnCl2 in HCl).

Cheers, Justin

I was just thinking about this earlier today. We have a fridge that is constantly needs to be defrosted. (About time we bought a modern one, so that I could use this as my beer fridge). The Missus is having a Birthday next month, and I am always at a loss of what to buy her after 37 years of marriage. This thread game me an idea, thanks guys. I will buy one of those Benzomatic torches and learn how to use it at Bunnings on one of their teaching sessions and present that as her present. After all we are both practical now in our years of marriage. "I will need to defrost that fridge dear, and I thought this will be cheaper than buying a new one", at the same time, let her know that it is about time we bought a new one, it might be cheaper in the long term (After I bought the blow torch of course)...

:chug:
PeterS....

You think that will work???

Yep Bunnings and most hardware stores should have them. The MAPP gas ones would be good also (hotter flame so you can silver solder and braze) but they are around $70.

No lessions needed, piece of cake.

guys you got it wrong the hot air gun is for defrosting the fridge/ freezer. the blow torch is for fixing the hair dryer, sunnies and other associated equipment

Reminder: remove glasses from face before "fixing" with blowtorch.

I got a blow torch from Bunnings, one of the ones that hooks to a normal BBQ gas bottle on a long lead. Has a paint scraping attachment also, so of course its for "work" stuff!

Its awesome :D
