Nut centering tool for welding

[Tuomas]

First

I know, there is weldable nuts.

But, those need accurate hole where to be installed.
Sometimes fitting takes a lot of time, still its possible that result is off centered.

So, i made this tool.









Idea is simple.

Cone shape centers nut.
When tool is tightened, it also clamps nut to its place.

Material is copper, it prevents nut, or splatters to weld on to the tool itself. It also works as a backing, keeping threads of the nut in shape. If temperature rises too high.

No need to chase threads after welding. ( Unless welds are messed up really bad )
