Hello, All,
Since I think many of us are stuck at home due to quarantines and other restrictions, this might be a good time to revive this subject. Unfortunately, I haven't been in my shop all October due to some personal matters, but those are finally over. The last thing I was working on was a PC board holder that would allow the board to be rotated quickly to work on either the component or solder side. The base you see here is a casting off of an old drill press. The two blocks have slotted holes that allow movement and are locked with a bolt. You can see the only portion that I purchased in the background. These long arms are slotted to restrain the printed circuit board, while the lever on the left is spring-loaded. Rotating it releases the PCB so it can be removed or a new one inserted. I am currently working on a component that will hold the cross-piece. This component will have a spring-loaded ball in it that will drop into detents in the mating shaft to allow for quick rotation. The second two photos show the mating shaft being detented and a groove being added for retention.
More photos when I make further progress!
