Hi Chuck, I would flux both parts, press them together then put a ring of silver solder around the shaft (sitting upright, clevis up) so that it rests on the flat piece and braze. You should be left with a fillet from the flat piece to the shaft. I would think that should be strong enough. Fire brick can be a pain to track down. Home Depot sells HardiBacker board which is used to set tile on for kitchen or bathroom surfaces. It is cheap, can be cut up easily into any size/shape and will stand up to MAPP temps. Been using it in my hearth for a few years, no probs. -Dennis |

During my research for my silver soldering project, I cam across the .pdf linked below. It has good info including pictures of a reducing flame. I had run across several references to a reducing flame but this is the first illustration I've found. www.richard-whitehouse.co.uk/Soldering%20notes.pdf I also found fire brick at Lowe's. Chuck |

Hi Chuck Thanks for the pictures. Those parts are really small compared to what I imagined. Should be very easy to silver solder using a thin pallion (piece of silver solder) bent into a ring. just flux the parts and go for it. I know that even the thinnest of my silver solder supplies will still be way in excess of what is needed for that job. Being so small it will not need a very powerful torch. Once it has been brazed but before it gets cold (say 2-300C) if you dunk it in a tub of water all the flux will come off leaving you with much less to clean up. Hope you post pictures of the finished project. Best Regards picclock |

picclock, I've gotten so much help on this project here and on other forums, I would be foolish not to post pictures! Probably get drummed out of the forums... I had a small accident with the flux in the kit I bought. The plastic bottle shattered in my hands when I tried to open it. Now waiting delivery of a replacement. The first 7 or 8 rods that I made had to be tapped into the flat piece with a hammer! I cannot pull them apart with just my hands! I was thinking about all the advise to allow clearance for solder wicking and upped the drill bit 1 size for a couple. Definitly a slip fit on those. I'll try soldering the loose ones first. Chuck |

I think in this case, a tight fit is fine. The fillet will add the needed strength. |
