I bought a second hand dolls pram for my grand-daughter to use at my house but I noticed there is a rod underneath the body that slots into a hole but it was originally soldered.
Is it possible to use some sort of glue to repair it. I can't solder it back
The right kind of araldite will glue metal to metal, make sure it is clean and grease free. You can also get putty type stuff that comes in two parts that you knead together that will glue the bits together and fill in any gaps, again make sure the Metal is sound and rust and grease free.
The best glue I know of is Liquid Weld which I saw for sale at Cosford Air Show but have never seen since. Can anyone tell me the number for it if they have it?
I doubt very much that it was soldered, welded maybe but unlikely soldered, maybe even brazed. I have a little experience with gluing metal but it failed every time.
