![]() 62 forum posts 1 photos | Several visitors to the MMEX this year asked me when I was doing a brazing demonstration. Some of you may remember we used to join a couple of bits of copper on the CuP Alloys stand to illustrate some of the principles of creating a sound brazed joint. Unfortunately due to health and safety restraints, we have been prevented from lighting the torch. Being able to show what you are buying and how to use the products have been a cornerstone of our service for many years. So in order to offer something close to this service, we now feature a video clip at www.cupalloys.co.uk showing fluxing and heating techniques. There is also a video clip showing the flame profiles of various Sievert burners, helping you choose the right burner for your application, whether it be preheating, precise heating, inside eg the firebox, etc. Of course, should your clubhouse regulations allow, we can bring this demo to you along with a more detailed discussion about the brazing history and process, either physically, or by Skype link. Please contact us for details.

1193 forum posts 59 photos | Seems strange that they do not allow you to run a quick demo under controlled circumstances now and then but allow the small gauge live steam loco's to run all day. Also allowing some of the hot air engines to run a naked flame. I wonder when they will stop that happening. Maybe they should stop the catering trucks using gas to cook on. H & S gone mad once again. |

![]() 334 forum posts 1 photos | Regular readers of these pages will know that I have, for many years, been banging on about how to achieve strong leak tight joints by sticking to the basic principle of silver soldering - namely capillary flow. This principle applies no matter which alloy you use or from where you get it. Now my good friends at CuP Alloys have transferred the written words into two video clips to show this principle in operation The first shows metal flowing under capillary action to produce the joint. The second shows the flame characteristics of various propane burners (possibly used in association with oxy-gas torches) that will produce the heat patterns to promote the metal flow. Silver soldering is a simple, albeit skillful, operation. It requires no shortcuts. To attempt to do so will, and does, only result in tears! Every model engineer should aquaint themselves of the content of the videos and apply it. They also have an excellent book that explains why sticking to the principles is so important. And for those who demand transparency - I am retained by CuP Alloys and the book is mine! Fruitful viewing and reading! Regards Keith
