yes it is off topic but you see Tisme broached the subject and I followed on because there is no thread covering that particular subject....Tisme staring talking about asbestos and lead poisoning..

<runs for cover>
Excuse me, we were talking about lead brazing but you have wondered off onto soldering.
Silver soldering is something different again...We originally use Tobin bronze for brazing copper tube long before silver solder came into play which had a much lower melting point...Silver solder was great on copper capillary fitting where it could penetrate the whole joint...In my day we did not have capillary fittings and had to make our own tees and bends....Did you ever do any copper tube bending?
Now back to lead brazing what sort of flux and rod did you use on a lead joint?
I dunno, resisting and hysteria is not a bad two out of three attemptA bit off topic for climate change aren't we ?

At a pinch borax powder and water paste
You're not reading through your rage again are you. LOL.
And yes I still keep my hand in using my benders, expanders, swaging tools, pullers etc. I have oxy sets and many MAP/Pro gas sets. Two weeks ago I was brazing 8" copper on a chilled water plant to help my employees out. I also helped stainless steel weld a manifold to header those pipes.
I have migs, tigs and stick welders and I can chew gum when I use them. I stitch weld, I plasma cut, even have spot welders.......I am a GOD! I have several personal workshops where large investments in tools, machinery and project cars reside.
I was classically trained in the railway workshops to gas weld, electric weld, braze and solder and what's more I had to pass exams including material stress and pull testing and boilermaking/smithing/plumbing is not my original trade, although now I have multiple certified trade qualifications. I would hazard a guess you have nowhere near an idea of just how able anyone here is and it probably galls you to think you might have been bested by a more ubiquitous person and someone who has a bigger gas axe tip than you do.
Dammit I have run out of red rags
Just another diversion from the real subject Tisme...I don't really give a stuff about all you welding equipment...You seem to be a JACK of all TRADES and master of none.
I want to know how do you braze lead which is 600 F (315.5 C) melting point?....You were the one who mentioned lead brazing....Now this time stay with the question...
When soldering what percentage lead and tin did you use on galvanized iron, copper and lead?...What flux do you use on each metal before soldering?
You can use copper benders on small bore copper pipe but how do you bend copper tube of larger diameters like 2"...3"...4"...and 6 ".?
You don't braze lead at 315.5 deg C. You soft solder at that temp master of none.
We were trained to make zinc hydro-chloride flux via hydrochloric acid and zinc and use resin/rosin fluxes on the electrical joins. We would work PGI with blow torch and stick solder and still do on sealed ducting, although a Birko style electric is our choice of preference.
We pull large bends when resistance is a problem otherwise buy preformed. If you need a masterclass just ask. We also have hydraulic mandrel benders
Hardly worth making a science out of a home economics level trade.
BTW my record for apprentices of the year is fairly impressive for a master of none.
Why did you mention in your early post about brazing lead?...Now you are saying you don't braze lead...You seem to have contradicted yourself on this occasion.....Perhaps maybe you wish you had not opened the subject.
Yes you can soft solder lead but you are obviously not familiar with lead burning where you do not use solder...I lined dozens of acid vats 8'x 4'x 4' deep and no solder could be used...these vats held Surphuric and Hydrochloric acids......Solder and acid are not a good combination...Now then would you like me elaborate on the process so that you have a better understanding of lead burning?
I would also like you to tell me how you bend 2" to 6" copper tube.
No cobber, you'll have to learn how to punch above your weight if you think I'm giving you anymore free training.
Your comprehension skill are consistently woeful and I'm too busy writing intelligent posts on discussion boards and social media, while still running a company to get down an dirty over basic trade skills.
I'm kinda pleased you have something to hang onto from ancient Australia, but time marches on and so does rankings of technology as important.
I bet you still have a leather patch for lead wiping too
Well Tisme, I can see I have got you rattled because you do not have the answers on the subject which you started.......You don't know a bee from bull's foot about lead burning or copper pipe bending or the percentage of lead and tin solder used on various metals......so now you wriggle out by saying you are too busy....I have forgotten more about plumbing than you have learned.
I am sure you wish you had not started this conversation because it has become such an embarrassment for you.
For you to be running a company, you sure spend a lot of time on ASF.
Still trolling and jealous much I suspect.
If you want to know my basic training familiarise yourself with the once biggest workshops in Oz and many parts of the world and renowned for turning out he best trained in Oz for the many disciplines. You could never appreciate the skill sets I have and what's more I have no desire to debate them so you can attempt to debase them.
Your mealy mouthed behaviour, as usual, is to personify your obscurity and narrow focus as something of an exclusive club, a club that few have a desire to join. My mistake was to offer you some conversation about soldering and brazing, but as expected you went all magpie and attacked to protect your precious nest. My bet is you have few people who (can be bothered) argue with you in real life?
Heavy going in that post format Noco!
The lady is right, how do people think solar panels and wind farms are made? Disposing of toxic materials in solar panels will be a growing problem.
Second year running of coral bleaching onthe Barrier Reef.... who would of thought?
Press on with that Abbot Point coal loader, there'll be no reef for it to ruin shortly anyway.
From the WWF ....

Reports effected areas off Lizard Is This month...
"WWF oceans campaigner Richard Leck said he was “shocked and saddened by what is unfolding”.
“Scientists warned that without sufficient emissions reductions we could expect annual mass bleaching of the Great Barrier Reef by 2050,” he said. “Consecutive bleaching events have arrived 30 years early.”
WWF also released footage on Monday of severely bleached coral at Vlasoff Cay near Cairns, where cinematographer Richard Fitzpatrick filmed sequences for David Attenborough’s Great Barrier Reef series."
“Now with the water sitting at 32 degrees all the way to the bottom, the corals are dying. Many are already dead and covered in algae.”
“The reef is facing an imminent danger of mortality at a level that far exceeds last year over a greater geographical distance.”
Pictures of newly bleached coral were taken in recent weeks at Moore Reef, near Cairns, by the reef scientist Tyrone Ridgway, as well as by divers further south near Palm Island.
