LU6X-130
Instructions and Parts List
(including LU6X Basic)
Operating Instructions
Introduction
The LU6X is one the most versatile pieces of equipment available to the lapidary enthusiast.
It combines sawing, grinding, and polishing operations in one machine. Please read the
following specications and directions prior to using your Model LU6X.
Set-Up
Unpack the machine and check for shipping damage. If damage is found, you must notify the
carrier immediately and le a claim.
The LU6X should be mounted to a solid workbench with four 1/4” bolts or wood screws through
holes provided.
Motor Mounting
The motor is installed on the clip-on motor mount which slides directly onto the machine. A
2-1/2” motor pulley is supplied for proper shaft speed. We recommend a 1/3hp, 1725 rpm motor
(LORTONE # 300-022). A motor of at least 1/4hp is required for adequate operation.
The Model LU6X-130 comes with motor.
Install the motor on the motor mount using the bolts provided and tighten the bolts nger tight.
Slide the motor mount into place on the mounting clip on the back of the machine. Position the
motor so that the drive belt is just tight enough to eliminate belt slippage - an overly tight belt
can cause excessive bearing wear, noise or vibration. Motor rotation should be clockwise to drive
the shaft (show on next page, Fig. 1).

Blade Installation
A 6” diameter diamond blade with a 1/2” arbor hole is required.
Remove trim table from unit (see parts list drawings). Remove the
arbor shaft nut by turning it CLOCKWISE and remove the outer blade
ange from shaft. Slide the blade onto the shaft. If the blade comes
with an adapter bushing, be careful the correct bushing remains in
place during installation. Re-install the outer shaft ange and
replace the arbor shaft nut. Tighten the arbor shaft nut by turning
it COUNTER-CLOCKWISE. DO NOT OVERTIGHTEN the arbor shaft nut
as this can distort the shaft anges. Reinstall trim table.
Slight blade wobble is normal with thin lapidary blades. Loosening
the arbor shaft nut and rotating the blade slightly will often reduce
wobble.
Vise Attachment Installation
Vise attachment should be installed on trim table with self tapping
sheet metal bolts in holes provided as shown on the parts list
drawing. Care should be taken to assure that the vise runs parallel
to the blade. Alignment can be checked by clamping a pencil in the
vise with the point lightly against the side of the blade at the front.
Slide the vise with pencil to the rear of the blade – The pencil point
should lightly touch the side of the blade as the vise is moved
towards the back. (Fig.2). If the pencil point pulls away from the
blade or digs into the blade, loosen the vise mounting screws and
adjust the vise until the alignment is good.
Grinding Wheel & Sanding Drum Installation
The LU6X-130 machine has enough space on the right side to use
one grinding wheel, a sanding drum and a screw-on polish head
(items included with LU6X-130; not included with Basic LU6X). If
using a grinding wheel or sanding drum with a different inside
diameter, make sure to use bushings of the correct size. Check
with the manufacturer of the wheels for the correct bushing.
The grinding wheel is installed on the section of shaft that is ¾” in
diameter. Install the ¾” ID plated ange onto the shaft and slide it
up against the retaining ring. Install the 6” x 1” grinding wheel onto
the shaft using the correct plastic bushing. Install the second ¾” ID
ange onto the shaft. Install and tighten the ¾” Hex Nut against the
second ange. (Fig.3)
The sanding drum is installed on the section of the shaft that is ½”
in diameter. Install one ½” ID plated ange onto the shaft and slide
it up against the step on the shaft. Install the 6” x 2-1/2” sanding
drum onto the shaft. Install the second ½” ID ange onto the shaft.
Install and tighten the ½” Hex Nut against the second ange. (Fig.4)

Polishing Head Installation
The LU6X-130 machine comes with a felt-faced polish head. Insert
the ¼-20 threaded end of the polish head into the end of the shaft
and tighten by turning the polish head clockwise. Avoid contaminating
the polish head during installation.
For versatility, additional polish heads can be purchased either with or
without the felt. Leather discs can be attached to the rubber face
polish-heads with feathering disc cement. If these heads are used for
sanding and are threaded 1/2” N.F.R.H., they may be installed on shaft
as show in Fig. 5. If they are used with a polishing pad, it is
recommended they be installed on the shaft by themselves (see Fig. 6)
to eliminate possibility of contamination.
Sawing
Pour coolant into saw case until 1/4” of blade is emerged in coolant
(see Fig. 7). We recommend using water with a rust preventative or
quality oil formulated for lapidary use. CAUTION: DO NOT use
Kerosene, Motor Oil, Transformer Oil, or Automobile Antifreeze.
Feed material into the blade with even pressure. Never force the
material into the diamond blade. The rate of feed should never be so
great that the blade slows down. For difcult to handle shapes, clamp
the material in the vise.
Grinding
It is important to remember that the saw is still running while the LU6X
is being used for grinding, sanding or polishing. To reduce coolant mist
from the saw when using the grinding side of the machine, place a
small household sponge on the trim table directly in front of the blade.
When you are ready to use the saw, remove the sponge.
The LU6X is designed to be operated with either a water drip system or
a recalculating system.

Periodic Maintenance
The bearings used in this arbor are sealed and lubricated for life. The nuts and collars are plated to
resist corrosion. The shaft is stainless steel which will also resist corrosion.
Helpful Hints
If it is inconvenient to hook up water valve and drain on grinding wheel side of unit, an acceptable
option can be to place a small amount of water in pan and carry it to the grinding wheel with the use
of a house hold sponge (see Fig.8).
The LU6X-130 is supplied with a 2-1/2” pulley & V-belt. A precision turned, ground, and polished shaft
is mated with sealed for life ball bearings for smooth, quiet operation. The point to remember is that
the basic machine is a smooth running unit. Vibrations and noise, which can occur during operation
of your machine, can often be traced back to the items being installed on the arbor shaft (grinding
wheels, sanding drums, polishing heads, etc.) not being trued and balanced.
