I just realized that I have a legal duty of care to warn my not-too-clever lock-picker NOT TO TRY a mock-assembled piece of equipment, with for example the main weight-bearing bolt still missing.
(It is merely loosely held together, with even some parts still completely loose, not fastened at all because of missing bolts, nuts and screws.)
So I just printed a note that I stuck to the thing.
Does that feel nuts? Guess what.
There is case law on this.
I gave all my law books to to Advice Portsmouth a few years ago, but there is nothing wrong with my memory about some things that were in them.
