|  Holding
Starting to work on my first tuber. What is the best way to hold things where I want them when brazing? Does anyone use jigs?

I use painters tape, works perfectly.  Welding magnets I have found to be too heavy or not strong enough |

Ok, I was thinking of making like a clamp with some aligator clips, and a hanger. I waas thinking that way I could hold things where i need them.

I bought two cheap clamp on vices and attached them to my workbench. With a couple of welding magnets all has gone well so far.

ive found in the past that heat, removes the magnetic properties, from magnets, ie after having the torch near them and heated up, the magnets werent magnets anymore :( just paper weight, but they were ordinary "wal mart" magnets not welding magnets.

Yep, this is always something to be weary of, even if you look on the welding magnet label it mentions this. You just have to keep the magnets as far away from the flame as possible. I demagnetized many magnets when starting out because I got them too hot. Quote:

see thats just stupid, what the he11 is the point in having a welding magnet if it loses its magnetic property when it gets hot? id say use tape. ive seen a lot of people do it that way and most of them came ou very good. and dont forget if you ae bazing if it is crooked you can just reheat it and fix.

I just said to be weary, it isn't likely, but there is no use in demagnetizing. I haven't had any issues with the welding magnets in particular, just the magnets I had before. Quote:

Hmm, I was useing a magnet and it just split in half. So I think ill try the tape and if it dosen't work I am not out a whole lot of money. I am kind of surprised no one uses jigs.

Read through this thread it covers a lot of issues and I posted what magnets I've been using for just about a year now and they haven't lost the strength, just the labels getting burned off them. I also have an aluminum table extension that I clamp on to my work bench to braze on that allows me to move what ever I'm working on with out the magnets sticking to them. brake line/tubing ? I tried the tape thing and hated it. | |

For us novices it works just fine... just try a bunch of different styles, see what works best for you and go with it. Remember when building a tuber- Hot metal often looks like cold metal, stay outta the burn unit at your local hospital. | |

I use a bunch of the those tiny spring clamps. They work great. I don't know how many I burned through.  Also made a sandwich like clamp from two tiny pieces of wood and a bolt too hold the roof pillars on for mock up.

It is a cross between soldering and welding that works in a temperature range of roughly 1200-1600 degrees. The bond formed when brazing is FAR stronger than anything soldering has to offer, and some people say that in some cases it is stronger than welding, though I haven't seen this first hand. Here is more on the subject: What is Brazing? Quote:
