This is a new departure for me. I need to make small brass assemblies (fittings for a model boat) from small pieces of 1 and 2mm thick brass sheet, and they would look better if they were properly soldered rather than stuck with epoxy.

I managed to find brass-coloured solder: https://albionfireandice.co.uk/products/jewellers-... - meltng point 600 C.

- and need a precision torch (not sure what the technical term is) to aim a precise point of heat to complete the soldering. Can the panel tell me if these would be good for the job?

Dremel Versaflame 2200: https://tinyurl.com/y4dq9qqd - 1200 C

Dremel Versatip 2000: https://tinyurl.com/yy5x7xog - this looks like a soldering iron but it says ' An open flame can be created by removing the tip, which reaches a temperature of 1200 degrees Celsius.'

Another problem I'll need to solve is how to hold small pieces of brass in exact position firmly enough so the flame won't blow them over!

That link quotes a flow temperature of 700 degrees. Brass melts at 900 degrees. Controlling the temperature on small pieces so that the solder flows through the joint without melting the whole lot might be a bit tricky.

If the parts are close-fitting, use soft solder, flux, and a decent temperature controlled soldering station. Much easier, and with care the joints will be pretty much invisible.

Use a "helping hands" type device, toolmakers clamps, or wire the parts down on a perforated ceramic plate (honeycomb soldering board)
