 New Hydrodynamic Oil-bath Bearing Units Available Now!

For many long years, J. I. Agnew has been examining, adjusting, repairing and replacing bearing systems of all kinds, from disk recording lathes and turntables to tape machines, high precision machine tools, measurement instruments, industrial equipment and all manners of motor vehicles, from passenger cars to heavy trucks. Over the past few years, he has designed and machined countless bearing units to replace worn or damaged units on a diverse range of disk recording lathes and machine tools. Valuable experience was gained, which along with his solid engineering background, was put to good use in improving his designs further and further, up until the current stage of development was reached.

New Series 6100 Vacuum Platters

The ultimate vacuum platter is finally here, and it is very reasonably priced. After three years of exhaustive research and development and several prototypes of different versions, along with field testing, we have finally arrived at what we believe is the most advanced and accurate vacuum platter ever made.

Available in 14" and 12" versions, our Type 6114 and Type 6112 Reference Instruments are now available to order, in any quantity. Do you want 100 of them? We'll make them, and threw in a quantity discount as well!

Direct-Drive Conversion on a Fairchild Lathe

The Fairchild line of disk recording lathes, first appearing in the early 1930’s, featured a General Electric hysteresis synchronous AC motor, running at high speed, with a worm and gear reduction to drive the platter. While this system in its various permutations in their different models was impressively well made and performed well for its time (see here for a more detailed description and pictures), a direct-drive system with a floor mounted motor is clearly the way to go if the highest level of performance is to be attained.
