It was beautifully made in brass and steel and what's more it worked!
The program said he did not finish it because he simply ran out of

I thought the Science Museum rebuild showed that it could be built with
19th century engineering?  They deliberately didn't make it any more
accurate than Babbage could have, and they only found a couple of minor
difficulties.  One was that it was too hard to turn the handle, so they
geared it down.
Surely something that, if Babbage had finished the Difference Engine,
he'd have done himself?
