I remember when I first started tinkering with cars did not have a 24mm spanner, so welded two flat sections of metal together and then angle ground a slot then filed out to 24mm.
It promptly broke, as it split in two, down the(crap) weld a piece stabbed me in the hand and I spent 4 hours in the A&E having 12 stitches!!
Now that is more like it!!

ps a VERY nice nurse did the stitching so not all bad I thought, until she put a needle right into the cut, F**k it hurt.
