After many long years of research and development and long field testing of the various components, we are proud to present the Agnew Analog Reference Instrument Type 612, a brand new disk mastering lathe, now available to order.
Presenting a custom record centering accessory, intended as a very quick and simple way of centering vinyl records with oversize center holes.
This compact and lightweight accessory is simply placed on the center spindle of your turntable over the record and twisted, positioning the sharp edge between the spindle and record hole, taking up any excessive clearance.
Repairing an SA-74 suspension unit, from a Neumann VMS-70 disk mastering lathe, which arrived with the head lift/drop lever jammed in the down position, preventing the top lid from being removed! The Neumann SX-74 stereophonic motional feedback cutter head was still attached, as it had been glued to the mount adapter, which can only be removed from the suspension unit by opening the top lid! Several mechanical and electrical repairs, adjustment/calibration procedures and even a bit of machining on the 1961 Moore Special Tools Jig Borer later, it was fully brought back to original specifications!
The Agnew Analog Reference Instrument Type 631 is a high performance direct drive motor, designed for professional disk mastering lathes and turntables. It is usually positioned on the floor under the lathe or turntable, driving the platter directly by means of a long driveshaft, similar to the drive system of the Neumann VMS-70 and several other professional disk mastering systems.
We have developed a range of precision machined driveshafts that can be supplied in any length required for your applications, with end diameters to your specification. Each end could be made a different diameter, if required, and we can also supply a useful range of accessories, such as constant velocity flexible couplers, vibration dampers, soft-start clutches and mounting flanges, to suit your application.
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!
The Westrex 2B is a motional feedback cutter head, introduced in 1952 by the Western Electric Export Company. It followed hot on the heels of the Westrex 2A, dating from 1947, which was itself a lateral implementation of the principles first described by Wiebusch, Vieth and Yenzer in 1938, with a couple of relevant patents issued by 1939, for a vertical cutter head employing motional feedback.
Neumann cutter heads have a rib along the back, for mounting. Presto lathes, on the other hand, together with the vast majority of non-Neumann vintage lathes (Rek-O-Kut, Fairchild, etc.), have a mount with two slots, for cutter heads with two threaded holes on the back (Audax, Presto, Fairchild, RCA, etc).
We recently had the pleasure of having Symatic over, from Bristol, UK, for a week of training on how to cut (and how not to cut) records.
Symatic runs Cut & Paste Records, a record label attracting some serious attention among skratchers, with high quality releases of skipless skratch samples, lock-groove tones, beats, and relevant music.
Requests for a stylus tool kept on coming in, so we decided to design and manufacture them! We call it the Agnew Analog Reference Instruments Type 6019 and it is now available for sale.
Finding a Hardinge HLV can be challenging enough, especially if, like us, you happen to be located in Europe. At 1400 lbs, shipping and handling gets complicated. In a previous post, we described the joys of forklifting the beast onto a platform trolley (with suitable structural support added to the building), to get it to the workshop, though narrow corridors and doorways. Once there, it had to be lifted off the trolley and placed directly on the floor. With no chance of being able to drive the period-correct forklift truck into the shop, we had to get creative. A hydraulic engine hoist along with slings and tacks got the job done neatly. With the lathe on the floor and properly leveled, it was time to check it over, replacing, adjusting, lubricating and cleaning parts along the way!
The best finds always pop up in the summer, when everyone else is on holidays! Still, they are not always nearby or easy to deal with. When this 1954 Hardinge HLV precision toolroom lathe appeared on the horizon, it took all of 5 minutes to decide to go for it and one week of frantic international phone calls to organize everything. An engineer was sent to check it over, local transportation to an industrial machinery crating facility, international transportation, more local transportation and another week later it was finally in our yard!
The need for a new suspension for our recently presented Presto MRC-16 modification project brought about yet another innovation from our R&D laboratory: The Agnew Analog Reference Instrument Type 6021 Lathe Suspension Toolpost!
Inspired by the toolposts used in metalworking lathes and improving upon the cutter head mounting system used by Neumann, the Type 6021 will accurately and rigidly hold any cutter head fitted with a suitable bar, including Neumann, Vinylium and FloKaSon heads, as well as any other head imaginable, through the use of our Series 1400 head mount adapter range.
A simple yet effective movement which has seen many decades of regular use, appears under the lid of this dial indicator.
It was once able to indicate accurately in 0.01 mm graduations, through a gear train driven by a rack on one side of the spindle.
It started life in the 1940's as a completely manual machine. A sturdy design, capable of very decent results, these lathes were extensively used across the USA and other parts of the world for several decades. Many are still in operation today. In the original condition, they were quite limited in what they could do. But, as with most good lathes, they can take a lot of modification and improvement.
Stereophonic cutter heads developed by Neumann are designed to accept a cutting stylus with a conical shank, resembling a micro-miniature version of a Morse Taper, a type of fitting frequently encountered in machine tools, especially metalworking lathes. Vinylium and FloKaSon cutter heads also adopted the same fitting for the sake of compatibility. But most other cutter heads, especially all those predating the stereophonic era, used long, thin cylindrical shanks, often with a flat machined on one side, to allow a set-screw to align the stylus and secure it in place.
