Always wanted one of these, but they were a little flimsy for what I needed it. Also wanted to be able to tack together some steel brackets.
So after also needing a base for my NEW cell phone holder to take videos, I came up with my own helping hand.
Welded some 12mm ball bearing balls to 6mm rod, and made some wrists by drilling 5mm holes and countersinking them to march the balls. Then a 5mm screw and a wing nut and job done.
The base is a piece of 100 x 50 channel iron, strong enough to be clamped in a vice.
The clips can be unbolted from the arms to allow me to use some more substantial fixing methods for when I want to use it as a welding jig.
The magnifying glass has a built in LED and is easily removable when welding so I do not destroy it with welding splatter.
And most of it out of the Off-Cuts bin.
