I have decided on getting the Sievert Pro 88 toch system for my A-3 and general soldering projects. I am very much a novice with this type of soldering. I have done many a copper pipe or tubing for air concitioning systems but, thats about it. In reading Kozo"s A-3 Swithcher book he recommends the use of Easyflow 45 solder for all needs. Until I manage the pro 88 LP systems for heating can I get away with using a portible butane torch with attached burner with Easyflow 45 for small work. Or, will it not get hot enough. If not, Rudy Kouhoupt recommends the use of stainless steel solder (lead free) having a melting 450F for joining his non critical parts and things such as flywheel spokes. He uses a everyday butain torch bottle and attached burner for this work. Could Rudy's technique be used for general work on the A-3.
Thanks,
lee

A portable propane torch can indeed be used to silver solder small parts. If you can heat the parts to red hot with it, then they can be silver soldered. Valve gear parts, piping and the like can all be done with a portable torch, and I have done it extensively. For larger parts, you can try Mapp brand gas, as it burns hotter than straight propane. The Sievert Pro88 torch is an excellent unit, and you will enjoy using it. I have found that just the idle or pilot flame with the smallest burner is enough to do the job on small parts.

Thanks Larry. Will Easyflow 45 solder work with the portable propane or butane torch?

Lee,
Yes, the Easy Flow 45 solder will work with a portable propane torch. If the torch can bring the parts up to red heat, then the solder will melt and flow properly. Remember to heat up the heaviest parts of an assembly first, and let the heat from the parts melt the solder. You already have the skills how to soft solder; the same skills are used for hard (silver) soldering, only you are using much higher temperatures.
