      Hello everyone. This is my first posting at scalemotorcars. I`m from Austria (not Australia) and i`m building modelcars since 30 years. This is the first Project in this Dimension. Hope you`ll enjoy it. Sorry but my english is poor.

    That paillons technique is widely used in jewellery but sometimes impractical for large soldering like a frame. However, if you are confident with this method, no need to change!
    Hi Roger
    The melting points are :
    Hard 773C
    Medium 747C
    Easy 711C

    So if you're making a complex assembly with several solder operations, using a lower melting point solder each time allows multiple joints without melting the previous one.
    The solder will only flow where there is flux, and it's very important that the joint is completely clean. This can be used to advantage if there are moving parts where you don't want solder. A solution of mud (yes really - from the garden!) painted onto the work will stop solder in its tracks.

    I was only taught to use paillons, and on a long joint several small paillons spaced along the joint can work, but I have some solder wire now to experiment with. I hope it's easier, I lost one radiator for the Alfa through overheating the joint and melting the brass

    @ markus68
    as told in other forums You did an exellent work same way as Roger Zimmermann

    Soldering brass is even not a easy job even when some smaller parts have to be soldered one after another to a greater part of brass.
    The problem ist still to let the greater part at certain level of heat.
    So I decided to try it by resistance soldering. With this method You only put the heat to that place where it is needed.
    Some millimeters beside the soldering point no warm parts are registrated, so older "done" solderings keep soldered - exact what You want.

    Thanks confirming what I supposed about the temperature!
    The idea with mud is interesting!
    I don't have different silver soldering rods but I experienced that when a part is silver soldered, it needs more temperature to get loose again. Long ago, I tried to remove incorrect elements from a bumper; I could but the surrounding surfaces were so damaged that a new bumper had to be made.
    It happens also that while attempting to silver solder a tiny element on an assembly, the previously soldered part(s) said good bye! This problem can be minimized with the use of the soldering paste. However, when doing a complex assembly, I'm never sure if the result will be 100%. This is the way to stay humble...
    To melt the brass requires a rather high temperature, ca. 900C At that point the metal is cherry red, indicating that something is wrong with the soldering method!
