Brazing cast iron
OK so I'm convinced that using JB weld won't hold up so I'll try
brazing this cracked plane I have. MAPP gas What tip? Can I just use the same tip I use with propane to sweat copper pipe? What kind of 'brazing' rods? I was surprised that HF didn't carry them these? http://www.amazon.com/Bernzomatic-Ni...8923442&sr=8-8 |

One thing that helped at the time was following professional advice that getting the cast iron body hot before brazing was wise. You may try a little spell in the oven first to accomplish that. Someone on RCM would know on the rod. Regards, Edward Hennessey |

I have been involved in a few cast iron repairs and Mapp gas is not the answer. You want an oxy-acetylene torch with a brazing tip. And like the other poster said, you want the cast to be hot (the oven thing won't do it). Use the torch to heat it up. A plane is not that big and will heat up nicely with a torch. Take a look at this site: http://www.weldguru.com/braze-cast-iron.html More info than you will ever need and what kind of rods to use. Good luck! -- Robert Allison New Braunfels, TX |

Brazing cast iron
... I'll try brazing this cracked plane I have. It's not worth the time and effort. There's a strong possibility that the heat from the brazing will distort the body and it will be a nightmare to get the plane to work properly. Salvage whatever parts you can and toss the rest. |

It has been repaired by riveting the broken piece back in with a steel backing plate. I love the plane, it is filed smooth, works well, and it means something that a previous owner cared enough about it to go to a lot of trouble with the repair. |

The patent holder went under and the patent has another 10 years or so to run before somebody else can start making it. I believe the replacement is propylene, which supposedly burns about 50 degrees cooler. If you're looking for a MAPP torch and can't find one that's the reason. |

Cheap Ross 10 speed, seeing if I could pretty it up. Bought the parts -- cable and bottle bosses, not lugs (apologies) from a local frame builder. Worked fine, didn't seem to hurt the frame. |

Brazing cast iron
To all who said you can't braze with MAPP gas, you were right... ++++++++++++++++++++++++++++++++++++++++++++++++++ + You need to use MAPP with oxygen. That is enough to braze most things. When you are talking about heating up something as large and heavy of a heat sink, like a plane body, it will take a good portion of both, especially the oxy. You can braze lighter things with straight MAPP. It gets hot enough if the workpiece is light enough. If you don't believe that, go talk to guys that do air conditioning work, day after day. -- Jim in NC |

Agreed. I was able to get the side piece that cracked off hot enough for the brazing to stick. I could get the main body red by using a propane torch on one side and the MAPP on the other, but not the bright red color needed for brazing. |

To all who said you can't braze with MAPP gas, you were right... Did you remove the wooden pieces and toss it in the oven at 400 degrees to warm up the casting first, just before brazing? I suppose I could try that one day when SWMBO is not home... I tried using an older BernzOmatic TS4000 that is good for MAPP and propane but does not have the newer 'swirl' tip. *Could not get the bright red color needed on the thicker piece. *I have googled but have been unable to find a source to buy just the screw on tips. *Does anyone know where I can buy just the screw on swirl tip? I called BernzOmatiC yesterday and they said this tip will fit on my push button torch. http://www.grainger.com/Grainger/LEN...ZL3?Pid=search Looks like the BernzOmatiC and the Lenox torches are made by the same company http://www.bernzomatic.com/Portals/8..._019040_lg.jpg http://art4gis.com/gra/4NE81_AS01.JPG I guess I'll swing by Grainger today and pick one up. |

BernzOmatiC OX2550 http://imagethumbnails.milo.com/009/...22_trimmed.jpg Worked great. Got the cast iron bright red in less than a minute. Being my first time it was a little messy but nothing a belt sander couldn't take care of. |

I might have tried a file before a belt sander, but you're the one doing the work. Bill |
