L-W Slow Speed Drive - The Slow Speed Drive is designed to automatically rotate the headstock at differing speeds, and can be engaged or disengaged using a simple clutch mechanism. The headstock can still be turned using the hand crank, however, when a slow speed is required the drive can be instantaneously engaged or disengaged.

There are many advantages of using the Slow Speed Drive. These include better finishes on your final cuts by turning the headstock at a slower rate with no jerkiness in the movement, allows you to concentrate on the slide rest when making adjustments, using the drilling frame to drill large holes in boxes, reduce tennis elbow, you can leave the ornamenting to the RE while you drink coffee.

The Slow Speed Drive is driven by a DC parallel shaft gear motor and V belt, which allows for extremely low speeds yet can attain higher speeds due to the variable speed control attached to the motor. It is not possible to rotate the headstock at such a constant slow speed using the hand crank. While the drive was specifically designed to work with the steel stand it can easily be fitted to a shop built base especially those made according to the L-W plans.

3/16” end mill holder , 3/8” end mill holder, and 60 degree thread mill cutter Threading Attachment

The threading attachment mounts to the outboard end of the spindle by means of a collar and set screw and functions in the same way the traditional Holtzapffel lathes did by means of engaging a threading chaser into a threaded bobbin of the same pitch. The attachment comes with four sets of thread pitches or threads per inch (they are 4 tpi. , 8 tpi., 12 tpi.,and16 tpi.) and is capable of making one, two, three, or four lead threads which gives a wide variety of threading options. The thread chasers are made of brass and the attachment holder, collar and four threaded bobbins are coated in black oxide to prevent rust. The lever is used to engage the thread chaser firmly into the bobbin and hold it while it’s being locked down by the cap screw.

Cutting the threads – The Threading Attachment is used with the Drilling Frame using a 60 degree cutter to cut a thread in the work piece. There are two options for cutting threads. The first is to use a 60 degree cutter held in an end mill holder. Only the 3/16” end mill holder is supplied with the purchase of the Drilling Frame. The second option is to use a 60 degree thread mill cutter which is held in a 3/8” end mill holder. Both parts for the second option can be purchased from Lindow-White.

The Threading Attachment can also be fitted to most MDF rose engines.

Expansion Chucks - The expansion chucks are designed to hold objects both internally and externally. Internally they tighten against the work piece by means of a draw bolt and conical shaped nut which forces the slotted section to expand. Externally they perform like a cup chuck being closed by means of a hose clamp. Both methods offer a secure and accurate means of holding your work piece with a low profile. These chucks are the perfect answer for holding objects where space is at a premium such as on the Dome Chuck. The chucks are made of Delrin, a high impact plastic that is durable enough to hold an object firmly yet flexible enough to effectively expand. They can also be turned to any specific size needed to hold your work piece.

The Expansion Chucks are either sold as a set of 18 pieces, or can be bought individually.

A set consists of 18 chucks. Included are 8 chucks threaded 1”-8, and 8 chucks threaded ¾”-16. 2 blank chucks, with both thread sizes, are also included. The set also comes with 10 conical nuts and flat head ¼”-20 bolts.

For internal holding the diameters of the chucks are 1 1/4”, 1 3/8”, 1 1/2”, 1 5/8”, 1 3/4”, 1 7/8”, 2”, and 2 1/4”.

For external holding e.g. as a cup chuck, each expansion chuck can clamp a work piece ¼” smaller than the diameter of the chuck. For example, a 1 ½” chuck will be used to clamp a 1 ¼” work piece.

For a set of 18 chucks, $350 with nuts and bolts.

Individual Chucks, $24 each without nut and bolt.

Nut and Bolt set, 5 for $20

Engine Turning Tool Holder - The engine turning tool holder is designed to allow traditional engine turning or guilloche work to be done using a tool slide and quick change tool post. It incorporates the traditional cutter (high grade Mirco 100 carbide) with a guide (geed) immediately next to it. The cutter is ground with a front angle of 10 degrees off each side and a relief angle of 20 degrees. The guide is adjusted by means of a thumb screw which in turn sets the depth of the cutter. The cutting tool is made from extremely close grain carbide of the highest quality and honed to a mirror finish for exceptional cutting and a highly reflective finish cut. The tool holder will accept ¼” square cutters for additional tool profiles.

Crossing Wheel - The Crossing Wheel allows for very quick and extremely accurate phasing of the rosettes without moving the position of the work piece being ornamented. The Crossing Wheel is constructed of four main parts. They are the barrel, the crossing wheel, the worm, and the worm wheel. Barrel – the barrel rotates on the spindle and holds the rosettes. Crossing Wheel – the crossing wheel has sets of three notches for each of the 12, 18, 24, 36, 40, 48, 60, 72, 84, 96, and 120 count rosettes. There are also three sets of graduation notches for 96 divisions, 200 divisions, and 300 divisions. A spring loaded detent is inserted in the notches to secure the crossing wheel. Worm - The worm turns the worm wheel using a detachable handle. Each full turn of the handle moves the worm wheel 2 degrees. For even more accuracy the worm itself is also divided into 10 divisions. Worm Wheel – the worm wheel has 180 divisions cut into the wheel surface. If the worm is turned 180 times the worm wheel is moved 360 degrees one compete circle. The Crossing Wheel is supplied with an instructional video explaining its assembly and maintenance.

Phasing Using The Crossing Wheel – A simple example of phasing is to first insert the detent into the notch that corresponds to the count of the rosette that is being used in the phasing process. For example, if you want to phase using a 24 count rosette first insert the detent into the 24 notch. By moving the detent to the notch on either side of the 24 notch the phase is changed by half or 50% of one valley or bump of the rosette. By moving the detent backwards and forwards in the notches basket weaves and barleycorns patterns can be made. Also, using the graduation notches of 96 divisions, 200 divisions, and 300 divisions basket weaves, herringbones and chevrons, as well as many other designs, can be made. For those trying to accomplish engine turning the Crossing Wheel is a must.

Phasing Using The Worm - The worm is not only used to make designs using odd numbered rosettes and making moirés, it is also used for quick alignment of the spindle especially in regard to the Dome Chuck, Double Eccentric Chuck and Straightline Chuck.
