The idea of one hand holding one side of an item.
And the other, rather blindly reaching to locate or put it into place via a screw, bolt or nut.
Too awkward to eyeball the piece into position.
And mere gnats wings away from locating or engaging into place.
Which might as well be miles, if you can't join the parts
That is when the finger on a bit of string
or an extending finger,
Or
elongating neck to see into or over said item to guide visually
Would all come in mighty handy
All just variants on a finger on a bit of string
A much wished for impossible item.
Usually prayed for by good Anglo Saxon utterances, as frustration makes one go all route one and
reach further & harder then is good for one
Bruised knuckles & fingertips the only return on the prayers investment, sadly.
Then it's back to the drawing board for inspiration .
And a little reflected muttering
"It's only meant to be a 5 minute job
