Page 3: Introduction
The Fantasy Machine has gone through a period of extensive testing – tweaking – modifying – getting it right. That period included learning – a learning that continues – but clearly, it was time for the Fantasy machine to be introduced. -
Page 4: Unpackaging The Unit
These are the included items: Please note that the Fantasy Machine is heavy, so you may want someone to help you with lifting it out of its shipping box. Have a sturdy surface to set it onto. -
Page 5: An Overview
Slitting tools (disc “grooving” tools). These are the positioning features: ● Initial Alignment – the faceting Mast is set onto the Fantasy Machine and aligned to a “home position” – an initial retrievable 0 reference. ● X (in-out) directional positioning (“parallel stepping”) of the grinding/polishing tool, relative to the workpiece is provided - Dial indicator readout. -
Page 6: Setting Up
3.0 SETTING UP 3.1 The Machine – The machine should be placed on a workbench or desk surface. It is fairly heavy, about about 65 pounds, so be sure the work bench is sturdy and you may need assistance in lifting it to the surface. - Page 7 3.3 Install Drip Tank - The Drip Tank post slips into a black Bushing in the left rear of the Reciprocating Table (see the picture on right). Place the Drip Tank onto the post, position the Post into the Bushing, tighten the set screw, and it is ready. The flow rate is adjusted by turning the valve stem, and the water shuts off with an easy pressure.
- Page 8 3.5 Install Lamp The Lamp mounts onto the pre-assembled stud located in the right rear corner of the Baseplate. The Lamp Mounting Lock has a Snap-On design. Pull back the nylon ring, place the Lamp onto the stud, and push down the ring.

4.0 OPERATION 4.1 The Control Panel The Electronic Control converts AC current to DC, which the motors require. It contains controls for both motors that are part of the unit, the Tool-drive Motor and the Reciprocation Motor. Note that the motor controls are independent –... -
Page 10: Tool-Drive Motor Position
Tool-drive Motor position. There are two optional positions for the Tool-drive Motor. Position 1, shown in figure 1, is the position in which the unit is shipped, and the position in which the initial setup alignment of the Mast to the machine is made. Position 1 is the “main setup position”... -
Page 11: The Mast
Position 2 continued: Slide the Motor into position – push the Drive Motor firmly against the rear of the Spacer Bar - the rear pins on the Bar will engage the notches on the face of the Motor Housing. Lock the Drive Motor there. The Mast-Most often, preparation of the workpiece is done on the standard flat Faceting Machine, and after the preparation is complete, the Mast, holding the stone, is moved to the Fantasy unit for further work.(in “concave”... - Page 12 4.3.2.1 Affixing the Lateral Stop Bracket to the Mast. For fantasy cutting, it is necessary to eliminate lateral swinging of the Yoke – to align the Quill, and the dopped stone it holds, on the centerline of the Grinding- Polishing tool. To do this, a “Lateral Stop Bracket” is provided – it mounts onto the Mast. Here are the mounting steps.
- Page 13 Mounted. The forward Screw pointed at the Yoke is treaded in, making contact with and stabilizing the Yoke. Tightening (or loosening) that forward screw can be used to tweak the set lateral position. Now, - final setting of the aligned HOME position The Position 1 “Home”...

d) Then, set the quill at 90°, pointing forward, with the Mast height position set so that the dops are in the same horizontal plane. This level setting is not critical, it just needs to look ok by eye - it will look something like this photo (there has been nothing “critical”... -
Page 15: Horizontal Positioning - X, Y, Θ
Set the right-angle Alignment Plate in place (down onto the plate) the back edge pushed against the face of the Drive Motor Spacer. Slide it toward the tool. The V groove in the Brass Rod will engage the tool - the Brass Rod moves in and out - longer or shorter - to manage engagement with the tool. -
Page 16: Y Positioning
Plate in position, set the Quill of the Mast onto the top edge of the Alignment plate (as in 4.4, figure 4 – but keeping the Mast firmly locked to the Mounting Block), drag the Quill along the top of the Plate toward the notch by rotating C. -
Page 17: Tools
Note that when the Y traveling Plate is rotated to a new θ position, it carries with it the Reciprocation Mechanism – continuing the reciprocation in line with the cutting action. At time of alignment, θ is set at 0º (left photo). To change the θ... -
Page 18: Cylindrical Tools
5.1.1– Cylindrical tools Cylindrical tools (commonly referred to as “mandrels”) are used when the Drive Motor is in Position 1. In that position the reciprocation action is always in line with the axis of the tool. Regardless of the θ position, the reciprocation action remains in line with the axis of the tool and the tool’s rotational axis is aligned to the rotational axis of the θ... -
Page 19: Cutting And Polishing Tools
It is a situation in which the selections are many, and the choice is growing. It is also a situation in which we understand that many purchasers of a Fantasy Machine have already ventured into this sort of work and have a collection of favorite tools. -
Page 20: Cutting Information
Special materials—that have been very successful in flat faceting – “Lightning Laps” and “Batt ● Laps” have made mandrels available. From the Lightning Lap page – “ The advantage of the LL- Mandrel is in the ability to have just one lap to do all your work, just by cleaning and changing the polishing medium. -
Page 21: Appendix
● When using a ball end cutter, straight forward plunging leads to swirl marks (the dead center isn’t moving much – it’s a dead center all right). Approaching the stone from the side at some angle or other provides the same cutting profile, but much swiping action. ●...
