That half-way submerged option is a useful technique for soldering (or unsoldering) joints when using a torch, as brass can transfer heat quite quickly.
When I built this cast brass cab, from Kemtron, I tinned all of the mating surfaces, then assembled it by wrapping soft iron wire around it to hold it together.
I then used a plumber's propane-type torch to heat all of the joints, in-turn, then, once it had cooled, removed the wire. The cab roof was not soldered in place, but was modified to snap into place, to allow access for adding window "glass", or maybe a couple of plastic crew members....
