Dual Vapour and Liquid Management Still Head

Lots of soldering as I put the caps and 25mm fittings on. Because of the amount of copper that has been put together, it takes quite a while to get up to working temperature, so once the work is hot, I try to solder on more than one piece at a time. This also illustrates that if you're not using oxy-acetylene, forget it.
I did find it difficult to ensure that all the pieces lined up and were at right angles. Bear in mind that once the work has been heated and cooled it becomes annealed or soft. This does allow you to do some SLIGHT bending to fit. The 'fudge factor'.
