Amstrad's early PCs (1512, 1640) featured a job lot of non-standard sized 5.25" floppy drives. Apart from being half an inch shorter than anything else easily available, they have the power and data leads on the opposite sides from most replacement parts. None of this would be a problem if it wasn't for the fact that Amstrad wanted to try to sell the machines in the USA, and the FCC weren't happy with the plastic cases. So, all internal parts, including the FDDs, were encased in close-fitting steel boxes for RF screening purposes.
This meant that when you put a replacement FDD into one, it stuck out the front by half an inch and the sockets on the back didn't line up with the holes in the metal box. This is where your "Amstrad Adjusting Hammer" would come into play. You would take the largest hammer in the workshop, along with an old flat screwdriver or cold chisel, and smash the spot-welds holding the back plate onto the steel enclosure, then hammer the "lip" round the edge flat so the new drive could slide smoothly back through it until the face plate lined up with the case. You couldn't mount the drive without the box, and Amstrad charged a fortune for the spares which actually fitted properly, so this practise was widespread amongst official Amstrad dealerships. :D
