| Brazing Stainless?
Can you braze stainless steel brakeline? I tried, but i had no luck. I cleaned off the coating, fluxed, heated until cherry red, and applied flux. the flux rolled off and puddled on the tile i was brazing on.

Another thing to remember, is to apply the flux before you apply heat | |

| So should i try playing around with when i apply the braze? And i tried it both ways, before i heated and during heating. No luck either way. What do you use for filler when you braze? I hear of this #56 stuff, i cannot find it. Do you have a link?

Check out this link http://utrcrc.freeforums.org/k2-s-bl...zing-t369.html Here are a few highlights; Torch There are several to choose from, but my two favorites are; Smith Mini Torch - 23-1014 http://cgi.ebay.com/Smith-Little-Tor...item53de9b9702 Or visit http://www.smithequipment.com/ This torch is by far the best made mini torch on the market and works with Oxy/Propane or Oxy/MAPP Gass. It has replaceable tips, an 8' hose and comes with regulators for disposable tanks, available at Home Depot or Lowes. My second choice is the bernzomatic TS7000 Auto Torch. http://www.bernzomatic.com/PRODUCTS/...3/Default.aspx It's super cheap and will fit the bill for just about any builder. It doesn't get as hot as the Smith torch, but it's pretty dang capable and the instant light feature is way convenient. This little guy uses MAPP or Propane without the need for Oxygen. Solder In my opinion there is only 2 types of solder worth exploring; Harris Silv 56 Harris Silv 45 http://www.harrisproductsgroup.com/c...loys.asp?id=30 The best place to buy this product is at Humphries in American Fork or Spanish Fork. I buy Silv 56 rod without flux at about $40.00 for 5 sticks. It can be bought with flux, but I have never used it. Lance however says it works great! So what one do we choose? If your using a Smith Torch, then get the Silv 45 as it's a little cheaper and has a slightly stronger overall finish. If your using the Benz torch, then get the Silv 56 as it will flow better at the lower temperature. Both types of solder are awsome and will work great. Flux I personaly use AllState No. 110 Blue Flux It's a nice liquid that can be applied with an eye dropper for a precise application. It too can be purchased at Humphries for $7 - $10. There are pastes that are available, but there hard to apply and dry out easily. Save your money and get the liquid stuff. 3 Hands These are the only third hands work a crap; http://cgi.ebay.com/THIRD-HAND-BASE-...item414af0bfdb You don't want the aligator clip types as they loose there tension when heat is applied, and nothing is more frustrating than having your work move after meticulously setting it up to be brazed. 2 of those third hands should be plenty. Mike at Destination Hobbies stocks them and there worth every penny. That should get you started |

Personally I would not waist my time with any other solder than Harris. Nothings is as smooth, strong or easier to work with. Your welding supply store should be able to order it for you. |

What I do to help with this, is I have a fan blowing across my face to help move the fumes away, but wearing a mask is also a VERY smart thing to do. Eye protection is also a must | |

I've never heard of the fumes from stainless being toxic...is this new? I know galvanizing is dangerous.

Some forms of chromium (main additive to stainless) can be carcinogenic, but only if they are vaporized. It has a melting point 600*F higher than steel, so you don't have to worry about fumes when brazing or gas welding. Just don't start blowing holes in stainless with a torch.. Arc welding could vaporize a small amount of the chromium. Scale building shouldn't release near enough to cause a problem. Same warning as with all welding: keep your head out of the fumes, and allow plenty of ventilation. The fan and/or mask can't hurt, but isn't strictly necessary. |
