This is just an add to maybe inspire someone. I salvaged a lamp which was destined for garbage at work. The lamp has a snake-like, sturdy, neck which allows it to be directed where you need it. As I said the neck is quite sturdy so first I thought of using it for a tablet stand. Then I thought of all the times I need support when welding and stuff.
I already had the cheap wise-grip copy and the odd nuts and bolts. It is a simple build, some poor welding and cleaning and voila! The friend you need in the "workshop".
