Michell Engineering

John began his engineering career when he served an apprenticeship with Finchley Autos in the early fifties. Deciding to start his own business, he set up in his garden shed and quickly moved to a small industrial unit in North London. Working as a jobbing engineering company, he soon outgrew the premises so, during the mid ‘60’s, moved to Borehamwood, which is where the company is still based today. Although very much an engineering company, John also made scale models and it was during this time that he met Stanley Kubrick and built the space ship ‘Discovery’ for the film 2001 – Space Odyssey, later to become the inspiration for the GyroDec.

The Gyro SE is a variation of the GyroDec design. Doing away with the full size acrylic plinth and hinged lid of the Gyrodec and replacing them with a single acrylic spyder to support the turntable. This was done to reduce the overall size of the GyroDec and create a smaller more compact turntable.
-
Low contact area feet: The solid aluminium feet of the turntable are shaped so the area in contact with the supporting surface is very small, this is done to minimise the transfer of vibrations from the supporting furniture into the turntable.
- Three point spring suspension system: Three suspension towers are fixed to the acrylic base to hold the suspension springs in place and provide height adjustment for the sub chassis.
-
Weighted pendulum style sub chassis: Hanging on the three suspension springs, this provides a rigid dense platform to mount the main bearing, platter and tonearm assembly, ensuring there is no movement between them, while also acting as a ‘resonance / vibration sink’ drawing away unwanted vibrations from the sensitive elements of the turntable.
-
Inverted oil circulating main bearing: Contrary to traditional designs, our main bearing has the point of rotation at the top of the assembly, not at the bottom. This orientation allows us to fully lubricate the inside of the entire bearing while the platter is turning. We achieve this by way of a modified Archimedean screw that we machine into the inside bore of the bearing. The oil is drawn from a reservoir at the base of the main bearing up to the thrust ball at the top, fully lubricating as it goes, it then returns to the reservoir via a waste hole drilled into the bearing spindle. Lubricating the precision parts of the main bearing in this way means that any potential for noise or vibration created by the rotation of the platter is avoided.
-
Impedance-matched platter with solid brass weights: The platter material was chosen for its vibration dampening characteristics and because sonically it is a very similar material to vinyl, so it has a very neutral sound characteristic. The brass weights are added to give the platter extra mass and subsequently more momentum when spinning. This greatly improves speed stability and helps keep wow and flutter to a minimum.
- Free standing motor unit: The motor unit used to drive the turntable is completely separate to the turntable, meaning it doesn’t touch the turntable in anyway. The only connection between the motor and the turntable is the drive belt that drives the platter. This stops any noise or vibrations created when the motor is running, getting through to the sensitive parts of the turntable.
