The New MSR "Machined Spring"
 After
extensive experimentation with extension springs and
compression springs, we chose the compression type for two
reasons:
(1) Unlike the extension type, the compression
spring's rate of progression is much higher. This fact
helps our design to damp unwanted oscillations of the
sub chassis. And,
(2) access to the sub chassis and complete set-up are
all easier.
This being said, there are still many inherent problems
that plague spring suspended turntables throughout the
industry.
These problems include:
(1) The need to rotate the spring to find the level
spot when leveling the suspension.
(2) Side deflection due to uneven loads.
(3) Coil bind due to excessive loading of the
suspension.
(4) Uneven and non repeatable compression rate.
We have chosen to solve these problems. And with further
experimentation using 3 D modeling and spring geometry
software, we have devised a new concept in spring design
termed - a "Machined Spring".
These springs are manufactured from solid round stock.
The coil thickness and diameter are calculated to support a
certain amount of weight and compress evenly and repeatably
which translates into a spring that emits a consistent HZ
frequency. The springs are guaranteed not to experience coil
bind at full compression with a min. gap of .015" between
coils. Side deflection is eliminated by utilizing dual start
coil geometry. The ends are flat and parallel to each other
as they are a machined surface so this in effect eliminates
rotating the spring to find it's flat spot in relation to
leveling the suspension.
The classic suspended turntable has just been made
extremely easy and reliable to set up. There is also a great
improvement and stability in sound reproduction.
