Of late I have been using a Vacuum Cabinet to Glue joints, fretboards, braces and various other joins where the Cabinet is the appropriate medium to use.
I learnt dramatically what can happen if the piece that is being joined is not braced properly.
in the Pictures associated with this post you can see what happened to a neck and an inappropriately supported jig, if proper care is not taken to brace the neck and it’s jig. The forces at work in the Vacuum Cabinet snapped this neck like a twig.
