SHORT PENDULUMS

SHORT PENDULUMS
Clocks with short pendulum lengths(5 inches and shorter) will be very prone
to errors due to loose suspensions , loose regulator assemblies and loose bushings in the
verge. The reason for this is that the error caused is a large percentage of the total
pendulum length. If a clock with a 45 inch pend has a loose regulator screw that varies
by .1inches , then the percentage is .22%. The same variation on a 5 inch pendulum
would be 2% or almost 10 times as much error.
