There's a business idea just waiting for someone to do it- sized
manhole and drain covers! get 'em made oversize and find a bigass (but
short bed) lathe and turn to size.

Back in 1974, the electrical sub-contractor wanted to substitute 24"
covers for the specified 30" covers on electrical manholes constructed
as part of an airfield contract. When asked for justification for my
refusal, I told him "neither the airfield electrician, or my
electrical inspector (both of whom were present) will fit through a
24" hole, there was no more discussion on the topic.
