Having done some soldering in the past I would say the thing is to try not to melt solder in the wrong places! Easy enough to trim a slightly oversized lump in the right place, less easy to shift a huge gob four inches away from where you wanted it. I speak from experience of such things!TBH it’s all gone a bit mad with this project. It’s only a 900 x 550mm board on a coffee table but gawd knows how much I’ve spent since lockdown began... The ONLY thing I regret is using point clips rather than soldering.
However - I’ve got an Absolute Aspects ground position signal that needs it (soldering) so I’ve bought a soldering station, some solder and some flux. I’m less intimidated than with the airbrush so let’s see how it goes.
