Making a Circuit Board Soldering Jig for the Super Sixteen

With a big job of PCB soldering ahead of me, I decided to make the task a little easier and more repeatable by building a jig to hold the various parts in place while they're being installed.
In the past I've done this by attaching and removing the front panel by its various threaded fasteners, which can be fiddly and time-consuming. This simple home-made jig allows quick and easy alignment of all the critical parts and will hopefully allow me to build up complete modules much faster.
