Subject: springs
How does a spring shop dearch a spring? I never heard of a spring shop
or
dearching til I saw it on the list.
Is it applied pressure for a certain length of time?
Larry
Spring shops make leaf springs from flat piece of spring steel. They
bend it to the arch that is desired. By the same token, they can remove
some of the arch from springs by bending them in the opposite direction.
Because spring steel has elastic properties that want to return the
spring to it's original shape, it has to be over bent so that it will
achieve the desired shape when the pressure is removed.
Multi-leaf springs are disassembled and each leaf is de-arched and then
reassembled.
