Building Cascade ...A Walkthrough

Silver solder or sil-phos. Anything else just doesn't cut it. And silver solder flux works great for both.

---

Yeah I believe the ones I use are sil-flo brazing rods.But they don't require flux.I do have some brass brazing rods but they are more for welding rather then brazing.

I don't see any brass in the pictures. Those are all copper fittings.

---

I was talking about his brazing rods not the fittings :)
His brazing rods do look like copper, but he says they are brass.
I think I am going to go take a look at my brazing rods...

sweet! so ur going to have water pump throught the big copper pipe? then have the lil copper tube doin the -c cooling!?

Correct :) Its a pain if you get a leak though...

Ah ok they are brass, I never cared for them.As you can see in your picture it isn't flowing very well, it is clumping.They take alot of heat to flow well, which makes it easy to melt the copper.Also flux in a refrigeration system is no good, which is why I like to stick with phosphorous brazing rods.

Thats why im buyng an oxygene/ acetylene torch ^^

This is the condenser so temps will be ~30C+

But its much more quiet... the fan in the a/c was driving me crazy....

Yeah that is what I was using when trying to braze with brass rods.It just kind of clumped up and wnated to melt the copper more than anything.Could have been from not using flux, but in your pictures it still looks like it was clumping.Oh and if you try to weld with it and get it too hot, it pops all over you. :eek:

Oh about the fan, you could have got a light dimmer for it and ran it at lower speeds.They work very nicely that way.Although I have ran into one a/c that had a replacement motor in it, and at low speeds it hums.So that one didn't quite agree.

watch out when buying one.i found out years ago.the best ones are ceiling fan controls,i found some light dimmers wouldnt work with my 120mm 115v fans i used.but the cieling fans switches work.
just look some are and can be used with a motor.

Yeah make sure it is tough and can handle quite a bit of amps.So far the two I have used have worked ok, but one gets a bit hot.

Nice idea with the dimmer :D

Bought the new torch,not a oxygene-acetylene but a mapp gass brenzomatic

new torch

The brazing rods.... i use those that arent covered with flux cause they flow better

Some pics of the condenser..

:@

:D:D:D

I almost made the condenser, ~1-2 days ill finish it totally (with cleaning it up etc) and pressure test it (the outer pipe cause the inner is 6m of 10mm copper pipe) and ill start to mount eerything

ill also make few new things, a subchiller for the I and II stage and other toys :D + cosmetical work

good going my friend...
good luck,and if i can be of help let me know.

Who makes that torch head? I need one :D (How much did it cost?) Looks like your mapp bottle is the same as mine, fittings wise and canister wise, i havent been able to find anything to fit it yet...

Ooh, it looks like a JT539 head is only like $25, and in the US next week, perhaps i can pick one up...

Its sold as a brenz'o'matic for brazing ;0 Costed 100$ :0 you guys should thank god for not living over here :0 some things are simply crazy :0

And now some pics of the finished condenser :D:D

Its not sanded yet but its hermetic= doesent leak :D

looks ugly but its quiet and will be efficient

more pics :D:D:D

The pieces of pipe used to enforce the whole thing (before adding them the joints cracked)

2nd pic of it

pics of the enforcments made
