Too grand a title I think :-) It seems for anything you want to do when working on a PCB you need a minimum of three hands. I have a stand-alone hot air gun which I've had for quite some time and it's a fair bit heavier than the usual gun you get with a proper workstation. Trying to hold it whilst doing other stuff is tricky - and then you need to find someplace to put it down (hot!) to complete another task. Now I've seen holders and wanted to make something similar - but with a bit more flexibility to point the thing where I want, and the ability to move it right out the way instantly when I need to.
I had a DTI holder with magnetic base (similar to this:

Not sure if you can buy the arm without the magnetic base (perhaps as a spare part). When tested it easily held the weight of the gun when in locked position, and a quarter-turn on the locking lever allowed it to be pointed anywhere - including straight up out of the way. There is no sag and no flex, point it at your PCB and operate the lock lever and it stays exactly in position.
I have it attached to a gantry (you can see in the photos) at the back of my workbench and just about any part of the work area is accessible to it.
