THE MAST controls the position of the stone—radial dial, axial angle, and vertical position. The Mast provides the key to REPEATABILITY.

THE MAST’S ACCURACY, FIRMNESS, and STURDINESS is a prime feature. Unlike “floating” designs, which give way to the wedging action of the stone against the lap, the Ultra Tec Mast is completely resistant to undesired movement—it’s rigid enough so that very small angles, even 3 or 4, can be placed on the gemstone (this allows for easy shallow table facets--of the sort which is increasingly popular in modern gem designs). Also, the Mast’s firmness allows the performing of stones without special support.

THE ANGLE DIAL (A) sets the axial angle. Precision in setting this angle is critical to excellence in faceting. The Angle Dial, unlike a conventional protractor, is geared in a 6 to 1 ratio, providing exceptional accuracy--with spacings equivalent to a 12 inch protractor. It is a constant read-out device, telling you the angular position at each moment, and it has an easy-to-learn vernier readout, with repeatable 1/10 positions. The fine adjustments knob permits the “dialing-in” of the exact angle. Its antibacklash design assures repeatability.

VERTICAL SETTING ACCURACY--The vertical setting is performed with the Vertical Knob--easy turning, with a retractable crank and knob (B). The Mast is continuously calibrated, with a metric readout (if you’re more comfortable with English measurement, don’t be concerned. The scale is metric since gemstones are measured metrically---you will soon be thinking that way too). The stainless steel leadscrew (C) sets the position, and the top readout (D) has shows increments of .02mm (less than .0008inch). There is no backlash and no locking device to cause distortion---you set the position, let go---it’s there. Its repeatability is exact.

The handle (E) allows a light pressure, dampening excessive pressure against the lap.

THE INDEXING SYSTEM controls the radial position. The Index Gear (F) is a true in volute gear, and the detent that locks that position is a true in volute gear segment. This assures accurate centering and accurate rotation during use of the index vernier (G) (the “cheater”). The index vernier is a unique design, offering a single dial control with increments of 1/10, again providing exceptional accuracy and repeatability. Use of the index vernier does not affect any other setting on the machine.

DOP ALIGNMENT---The Dop (H), which holds the stone while you work on it, can be removed and later accurately reinserted. It is keyed for both rational position and depth by a chamfer at the back of the dop, which engages a cross-pin. A Calibration Bar is provided to maintain precise alignment as an Index Gear is changed. (All of this makes it an ideal machine for school or family use. It allows interruption of the work, while someone else uses the machine---or while you use the machine for another stone---and allows getting back accurately to the previous position). If you are considering Ultra Tec as a replacement of another machine, incidentally, you will probably be able to use your former dops, just by adding that rear chamfer---it can be done easily.

After half the stone has been completed, a transfer is performed keyed-dop-to-keyed-dop, and the pavilion facets are aligned with the crown facets. Sometimes, the facetor wishes to rotationally offset the pavilion and crown facets---some designs call for that---in which case the keying feature can be overridden.

READABILITY OF CONTROLS All scales provide ease readability. The backgrounds are black and the numbers are contrasting white. The dials are flush, eliminating any parallax problems.

POSITIONING ON BASE The head is easily positioned with approximately 9 inches of horizontal movement. The base lock (J) holds the position firmly. The head can be easily removed for transportation or cleaning purposes.

SMOOTHNESS OF MOVEMENTS Throughout, Ultra Tec uses precision ball bearings, resulting in a virtually friction free sense of feel. These ball bearings never require adjustment or lubrication.

TABLE GRINDING AND POLISHING The Tabling Adapter provides exceptional firmness, gripping the outside diameter of the Spindle, and placing the stone very close to the end of the Spindle, thus minimizing the sideward pressures that bother traditional inside-gripping tabling adapters.

THE BASE is the less glamorous half of the machine, but a good base is critical to good faceting. Ultra Tec provides the finest base in terms of both accuracy and quality.

THE BASE PLATE - The Baseplate (K) is made from cast aluminum tooling plate, aged at least 6 months to minimize residual stresses and is Blanchard ground after machining to assure flatness. The half-inch thickness, unlike thinner plates, does not bend under leaning pressure (which would disturb angular accuracy). Importantly, the Baseplate is fully hard anodized, to the hardness of sapphire, to avoid wear (it is not just a thin decorative coating).

THE PLATEN - This critical subassembly (L) which holds the lap provides exceptional accuracy--.0003 inch maximum vertical runout. The width of the platen—4 inch diameter on the Ultra Tec—is also important, providing broad support for 8 inch laps. The plated is machined of bar, not plate, to assure that there are no warping stresses. The platen/baseplate relationship is adjusted, calibrated, and certified during final testing.

THE POWER SYSTEM:

THE SPEED CONTROL - The Speed Control (M) is an infinitely variable, SCR type. It steps up to 1200 RPM, and has a separate on-off and directional control. A feed-back loop in the electronics increases voltage as pressure against the lap increased, maintaining consistent speed.

THE MOTOR AND DRIVE - The motor is 1/5 peak HP, DC PM type. Made to Ultra Tec specifications, it is industry rated at 10,000 hours—so you are assured of long service. External brush mount provide lifetime serviceability (there are 20 year old units, still going strong, on their fourth set of brushes. Working with the Speed Control, it offers excellent torque even at very low speeds. The drive is a resilient cone type – no noisy or inconvenient belts.

SPLASH GUARD - The rubber Splash Guard (N) protects gems in the event of accidental bumping. Being flexible insertion or removal of laps requires no special tools and the flexible wall clips down for girdle grinding. The Splash Guard, which is easily removed for cleaning, drains into a funnel in the Baseplate and then into a hose.

WORK STATION SIZE The 4 ½ inch height of the base means that it can be operated conveniently on a table top. Set into a work table, there is plenty of leg room. The machine’s 32 lb. With makes it easily portable

TABLE ALIGNER

This provides fast, accurate alignment of the Tabling Adapter. It is inserted into the Tabling Adapter and is used to align the adapter flat to the lap. It eliminates the effect of tolerance build-up, and when the Adapter is replaced by the dopped stone, it's right on right angle.

Order Code: 1351.7

DIAL INDICATOR ATTACHMENT

With all other accessories, we recommend waiting until you have been faceting for a while--to see which you want--but, we recommend the Dial Indicator Attachment immediately--we think it's an "everyone-should-have" accessory. In faceting, the "action" occurs between the stone and the lap, where you can't see it. Using a Dial Indicator Attachment, however, is like having "eyes on the lap"--you know exactly what's happening at the lap surface--with great precision (over ½ inch of needle travel equals 0.1°). You see exactly where you are--all the time.

REDUCED INSPECTIONS--Inspections are reduced dramatically--in roughing, by perhaps 90%--greatly reducing faceting time. Importantly, that makes the faceting process easier on your eyes--leaving them fresh for the final polishing.

FEELING--AND BEING--IN CONTROL--The Dial Indicator Attachment "talks to you" all the time--from the start of the grinding action to the end. It tells you how much material remains to be removed and how fast it's coming off--when changing laps, it finds the new surface exactly, without trial cuts--it tells you if you mis-index--it puts you "in-control". You know what's happening as it happens (instead of inspecting afterwards--often too late). Its advantages are not fully describable in only technical terms--it's as much the feeling and the knowledge of being in control that's so important.

Why a dial-readout, rather than digital? Because a dial is much better for keeping track of faceting (just as it's better for most "action" tracking--for example, remember those digital speedometers? Incidentally, what kind of wristwatch do you use these days?). The design dampens out indicator flutter, and dual ball-bearings eliminate backlash.

THE GUIU DOPPER

The Guiu Dopper is an accessory that lets you set your dop in an optimum position on the rough, to assure maximum yield. You position and control the rough relative to the dop mechanically—precisely (the picture tells the story better than words). The depth of insertion of the rough is settable, and then X and Y positioning is easily done. No more “eyeballing” it in. As you well know, a very little off on a small piece of rough, will lose a big percentage of the stone. The Guiu Dopper gives you control that translates into minimum material loss—and maximum yield.

Guiu Doppers come as Kits, including an Aluminum Pencil for marking the target on the rough, and a Centering Guide for aligning to the marked target. You use it in your Transfer Fixture—and you use whatever dopping technique you prefer, hot or cold.

Order Code:1746.1 Standard Size Guiu Dopper - Round Kit, holds rough up to 17.5mm (0.7 inches)

Order Code 1746.2 Standard Size Guiu Dopper - Emerald Kit, is for up to 16mm (0.6 inches) wide.

Order Code:1747.1 Large Size Guiu Dopper - Round Kit, holds rough up to 25mm (1 inche)

Order Code 1747.2 Large Size Guiu Dopper - Emerald Kit, is for up to 22 mm (0.9 inches) wide.

DOPS

We offer a large range of DOPS in Flat (F), Cavity (C), and V configurations. Standard F and C Dops are keyed, while V Dops are not--(because long-sided stones, like those cut in the V dop, are best aligned using the long girdle facet--but if you insist, there are keyed V Dops, at some increased price over the standard unkeyed). See the price list for sizes, (a 12 dop set is included with the faceting machine).

There are also SPECIAL DOPS, such as rectangular Emerald Dops, in F and V configurations, Thin Emerald Dops for tourmaline, and Pot Dops--which are oblong ("roasting pan" shaped) for transfer of Marquise or Ovals. For the same reason that V Dops are not keyed, Pot Dops are not keyed. Refer to the price list for sizes.

Order Codes: Various (see price list)

GUIU GIRDLE ALIGNER

Guiu Girdle Aligner—a parallel bar 2 inches long that can be affixed to your stone to allow you to adjust girdle position after transfer to almost perfect. The long bar allows a much better straight edge to align to.

Order Code: 1750.1 - Guiu Girdle Aligner

FACET SAW KIT

SAVES TIME--it's fast!

SAVES MONEY--it uses a low cost saw blade rather than a lap.

SAVES MATERIAL--the most important feature--the piece that is sliced off is most often large enough to facet--a nice "bonus". You dop your stone, pay attention to how it is oriented, and then, instead of grinding your material to dust, you slice it.

The standard Saw Blade in this kit removes only .009" of material, so your loss of material is minimized (some pro's report they can eliminate rough grinding of the mains). For cutting inexpensive material, a 012" more rigid blade is offered.

Order Code: 1357.7

INDEX GEARS

The Ultra Tec Mast comes with a 96 Index Gear--the most often used. Faceting designs specify the Index Gear, and the 96 and 64 cover about 80% of published designs. Changing Index Gears takes only a few minutes. The symmetry of a design depends on which numbers divide evenly into the available number of teeth on the Index Gear. For example, a 5-sided design will use an 80 Index Gear, a 3-sided design will use a 72 or 96, etc. Why does a designer choose one or another when both will allow the same number of sides?--well, the more teeth, the more subtlety of design is possible. Index Gears available are: 32 - 64 - 72 - 77 - 80 - 96 - 120.

Order Code: 1905.XX

-- Replace XX with the number of Teeth (example: 1905.77)

LAMP

There is a stud, that holds the Lamp, preassembled at the rear of the Baseplate . The Lamp's vinyl-coated gooseneck is 30 inches long, allowing easy location of the illumination relative to the facet surface. The Lamp accepts a 100 watt bulb. The double walled shade stays cool on the outside, avoiding accidental burns.

Order Code: 1301.7

OFFSET ATTACHMENT

This allows the preforming of Marquise, Oval and Shield shapes. Fitting onto the outside diameter of the Spindle, it provides up to 30mm of offset, calibrated in increments of .1mm. Four keyed dops are included. Instructions include tables for standard stone sizes, and a method for calculation of offset for any combination you'd like--You should understand that preforming is not an absolute necessity--after preforming, you are still going to put the dop into the Spindle and proceed with faceting, and you might want to do that in the first place. But, if you like the controlled feel of having a preform before faceting, the Offset Attachment is for you. It is easiest to use along with a Dial Indicator Attachment.

Order Code: 1816.7

OSCILLATOR

Developed for tables, but OK for any facet--it's slow, but accurate. It maintains steady speed and arc on the lap. At times, impatient people, finding a large table isn't polishing "fast enough" decide to "lean a little extra". The next thing they find is a new table advancing across the stone. So, if you're impatient--develop some patience, or stop cutting such big stones, or get an Oscillator and let it do the work.

Easy bracket assembly--The easily disengaged linkage allows you to leave it mounted when you use the machine manually. The kit also includes a set of weights to add pressure to the Tabling Adapter--Adjustable for any arc.

Order Code: 1379.7

90° TABLING ADAPTER

The machine comes with a 45° Tabling Adapter. This 90° Adapter allows greater working height off the lap surface, for large stones (but if that's your need, read about the Two-Inch Base, and then decide). Aside from height, there are some who say that the 90° position works better (does it?--we've learned not to argue with customers--so if you want it, here it is). Sturdy outside diameter type of mount.

Order code: 1310-7

2 Inch Base

This provides two inches of extra height for the Mast while maintaining its firmness. It's for cutting very large stones. Now, for an occasional large stone, the 90° Table Adapter can be used, but you have to scrunch down to view the Table. So, if you do many large stones, the Two-Inch Base lets you work comfortably, using the 45° Table Adapter (which provides an upward-pointing Table in the inspection position)). Lever actuated locking mechanism.

Order Code: 1365.1

FAUCET KIT

Many people prefer this to the traditional Drip Tank. The Faucet's main advantage is that it accommodates a larger supply of water (a gallon or two). Users also like the Faucet's small size. Keep in mind, to use the Faucet best, you would have a permanent place for your machine, since it will work with a larger water container. If you sometimes move your machine to other locations, that's OK--at such times just leave the faucet where it is, and take along the Drip Tank that came with the machine.

The Faucet is set into a fitting in the Baseplate (the same fitting that accepts the Drip Tank post). The bushing is located at the Faucet's base. The Spout is flexible and can direct the water to any position on the lap. In its most typical setup, the Faucet draws water from a container set above the level of the Baseplate (see the illustration), or, it can be plumbed to a water line. You supply the container--the typical water bottle available at the market--we supply the faucet, hose, fittings, and instruction.

Order Code: 1501-7

ROTATOR

It rotates the Spindle at a constant speed for round pre-forming. It's slower than you can do it, but it works while you're doing something else, and doesn't fatigue. It makes the preform very accurately round, using the Angle Stop to control the depth of the cut.

It installs and removes easily, mounting on the close side of the Mast, (so your Dial Indicator Attachment remains in place). It's handy for people with limited time who would like to have the stone ready for faceting when they get to the machine (if you're an evening faceter, it can pre-form your stone while you are having dinner).

Order Code: 1407.7

STOP INDICATOR

The Stop Indicator signals contact with the stop, offering both a sight signal and a sound signal--a red-light comes on when contact has been made with the stop, and also a buzzer (which is optionally-on).

The buzzer feature, in particular, is for speed. There's no need to look away from your faceting--just hear the "beep" and index to the next position--off you go---moving along very fast. The buzzer is located in the box--with a control so that its sound is muted enough so as not to drive one's spouse crazy (on the other hand, one's spouse might be pleased to hear the faceting moving along so fast). There is a switch to turn off the buzzer, when you want to.

Both the light and the buzzer are very sensitive indicators, detecting a step of only .0001". So, it's a better end-point indicator than the Dial Indicator Attachment (but it doesn't have that device's

constant positional readout. Does it make sense to have both? Yes--many people do.).

The Stop Detector is housed in a small (2.5" X 2.5" X 4") separate box that can be placed conveniently in the work area. The unit uses a standard 110V outlet--no worry about whether batteries are working. There are only two wire connections (they are supplied) to the Mast and a plug into the box. It's a very easy installation.
