Useful hack for broken rivet.

...and here's a useful hack for a broken bolt on a nuclear submarine:

Not as useful, really.

should have used CBF!

DIN 892, DIN 906, DIN 896, DIN 897, ... ?

Oh, these DIN numbers are from here:

Yes DIN are German Specs. I used some German sort of superglue once to fix a broken belt on a tape recorder, Not sure I'd chance it for something like a nuclear reactor though. Incidentally, I have a Dbx processor unit here. It looks well made, but is not. Two shortcomings with age. The rivets, simply plastic pop rivets, seem to be all that earths the phono sockets to the case causing intermittent faults, and the switches are crap and need constant cleaning. They are of the multi push button kind. I've seem better switches in Goodman's and Amstrad gear than these ones. I'm gradually replacing the rivets with self tapping screws and sprint washers, but there is not a lot to be done with the crappy plating on the multiway switches. Brian

You will have missed the humour brian, the picture shows screws for impossible situations, with descriptions in German e.g.

for diagonally drilled holes

for offset holes

Magnetic screw head for quickly simulating screwing

See Vanguard was yet another example of a Defence project massive overspend .... >>

Vanguard started what was originally intended to be a three-year Long Overhaul Period (Refuel) – (LOP[R]) – at Babcock International's Devonport facility in Plymouth in December 2015. However, the programme ended up taking almost seven years at significantly increased cost because of technical issues as well as further setbacks arising from the Covid-19 pandemic.

Easy to overrun and hugely overspend when Government is paying.
