I am beginning to assemble my brass,home made carburettor. I have faithfully copied the original. It is necessary to solder the parts together. However, some parts have to be soldered to other parts that have already been soldered. Is there a technique for keeping the old parts cool whilst heating up adjacent parts for soldering. The parts can not be soldered simultaneously.

Usual method is to use two or more solders with different melting temperatures, (use the higher temp one first)

You can use the old trick of wrapping the end you want to keep cool in a wet rag, or embed it in a cold raw potato.

Sometimes just clamping on a hemostat or attaching a piece of copper sheet with an alligator clip will do.

Good luck!

Further to this topic, adjacent to the item being soldered there is a threaded section. Obviously I don't want to let the solder run into this area. Is there an anti flux,something that prevents the solder running into the threads..... Vaseline,grinding paste,butter, 3 in i oil ?

If its silver solder I use either "lead" from a pencil of Tippex correction fluid . Never tried it for soft solder

Tippex works for soft solder.
