Charles Babbage''s masterpiece-Truck cover
The most
Truck cover was that one of the companies contracted to create specific elements of the machine put parts of it under the wrong heat treatment, and in the process warped and cracked the cams--there are 14 sets of cams which control the engine''s drums.

The problem with that, Horton explained, is that the malformed cams affected the difference engine''s handle, which must be cranked to operate the
Truck cover. It was almost impossible to turn, he explained.
"It wouldn''t have worked," he said. "No way."

The error cost the team six months of building time.
Another
Truck cover was that one of the main contracting firms working on the project went into liquidation just before the main construction process began, and that meant Horton and his small team ended up having to make many components and rework badly formed pieces themselves.

The biggest
Truck cover the contractor''s liquidation presented the team with was that many of the machine''s pieces had to be hand-fitted, and hand-filed so that they were in acceptable condition, Horton explained. That meant another four months'' delay.
