DIAMOND GLASS GRINDER

FOR PERSONAL SAFETY THIS MACHINE MUST BE PROPERLY GROUNDED

The power cord of this machine is equipped with a three-prong (grounding) wall receptacle to minimize the possibility of electric shock hazard. Where a standard two-prong wall receptacle is encountered, it is the personal responsibility and obligation of the customer to have it replaced with a properly grounded three-prong wall receptacle. DO NOT, UNDER ANY CIRCUMSTANCES, CUT OR REMOVE THE THIRD (GROUNDING) PRONG FROM THE POWER CORD.

UNPLUG YOUR MACHINE:
A. Before making any repairs - (Note: We strongly recommend that any servicing be performed by a qualified person.)
B. Before cleaning.

USE ONLY IDENTICAL REPLACEMENT PARTS TO REPAIR THIS MACHINE.

EYE PROTECTION
When operating the grinder, always protect yourself against eye injuries from flying glass. Either wear safety glasses or use the eye shield that mounts over the grinder's cutting head. The eye shield is preferable to glasses because it eliminates glass chips flying toward the face.

ASSEMBLY

  1. First remove the work surface by pulling it straight up. Then, install the pump stanchion (2) by plugging it into the housing next to the grinding head. Make certain that it is pushed all the way down.
  2. Next, you'll need the brass alignment collar. Install the collar on the end of the motor shaft (3). If the collar is touching the pump stanchion, the stanchion has not been pushed down far enough.
  3. Them, screw the 1/4" grinding head (4) into the end of the motor shaft (through the alignment collar). Use the white nifty tool to tighten the head.
  4. Replace the work surface.
  5. Install the rubber splash guard on the peg directly behind the pump stanchion.
  6. Add water. It takes a minimum of 16 ounces to start the pump working. Another 16 ounces (one pint) can be added before the housing overflows. If you keep the reservoir full all the time, you will find that the heads spray a good deal more water than if the level is kept lower.
  7. Turn the grinder on, and you're ready to grind.
  8. If, for some reason, you do not want to use the pump, the pump stanchion can be unplugged and the sponge inserted in its place.

OPERATION

When you start to grind, push the glass against the grinding head with firm, even pressure. The diamond surface cuts better and lasts longer with heavy pressure against it. Excessive pressure will not harm the diamond cutting head or slow the motor.

Some manufacturers suggest the use of an industrial coolant to protect the diamond head. Glastar does not recommend or discourage the application of a coolant. Coolants may prolong the life of the Glastar diamond head by 10 percent, but their costs far outweigh the money saved. In addition, coolants create a mess.

If your finger touches the diamond cutting head when it is rotating, it will feel smooth. The diamond surface is not nearly the hazard to fingers as is a belt sander or a silicone carbide grinding wheel.

As you grind, the water level lowers because of the spray. If it falls too low, the pump will stop pumping. Therefore, check both fountains (5 & 6) frequently to be certain that water is geting to the grinding surfaces. It is possible for the lower fountain (6) to plug up. If this happens, remove the stanchion and clean it out.

WATER PUMP

The pump automatically keeps the grinding surfaces of both heads flooded with water. This means that the heads will grind much faster and the life of the grinding surface will be increased tremendously.

The grinding head slings water as it rotates. The rubber splash guard catches most of this water, and it returns to the reservoir. Some of the water is thrown toward the operator, so an apron would be helpful. Although the spray is a nuisance, this increased water supply is a distinct advantage.

DIAMOND CUTTING HEAD
The diamond cutting surface of the head is 5/8" high. Glastar has installed the head so that the full 5/8" of diamond extends above the working table. If all the glass you grind is 1/8" thick or less, you will only use the lower one-fifth of the cutting surface. When the diamond cutting surface dulls, lower the head 1/8". This will provide a new, sharp grinding surface. When that area dulls, lower the head another 1/8" and so forth. This will allow five surfaces; each surface should last approximately 25 to 75 hours, a total of 125 to 375 hours of grinding from one head. If you grind 1/4" thick glass, you lower the head 1/4" to change to a new, fresh surface. This gives you two grinding surfaces per head.

It is difficult to quote a specific number of hours that the diamond cutting head will last. Like sandpaper, it does not wear out all of a sudden. Instead, the cutting head gradually begins to dull. The head's durability depends on the type of glass you are grinding and your definition of dull. The 25 to 75 hours per surface is an estimate. Some claim more than 100 hours per surface, while others change to a fresh surface after 10 hours. Of course you should expect far less life if you are grinding rocks.

Never grind any metals (i.e. lead, copper) with the diamond head. This will make the diamond surface unusable for glass in a matter of seconds.

To lower the diamond cutting head, loosen the set screw near the top of the head with the Allen key. The loosened head will slide up and down on the motor shaft with ease. Each time you re-position the cutting head, Glastar recommends the application of a lubricant such as Vaseline, to both the motor shaft and the cutting head. When re-tightening the set screw with the allen key, make certain the head is set against the flat side of the motor shaft.

To remove the 1" head, unscrew the 1/4" head and remove the brass alignment collar and unplug the pump stanchion. The small 1/4" grinding head can be used to grind holes in glass. Hold your piece of glass at approximately a 45° angle to the work surface and work your way through.

MAINTENANCE

The grinder's only moving part is the electric motor and no mainteneance is required. After using the grinder for a short period, you will find that a very fine white paste, made up of glass particles, collects at the bottom of the reservoir. The glass may also collect in the pump. Therefore, after two or three hours of use, remove the pump stanchion and rinse it out well. Also, wipe out the reservoir.

TIPS FOR USING YOUR GRINDER

Despite the grid-type of work surface, some finely-ground glass may stick to the top plate, and it can scratch smooth, soft glass, such as 3/16" or 1/4" plate, and some antique glasses. If you are working with soft glass, it would be wise to place several strips of masking tape on the bottom of the glass to raise it off the table.

If you use a paper pattern when grinding the glass, water from the cutting head will get it quite wet. If you intend to make two projects from one set of patterns, let the paper dry out before attempting to grind the second set. After the paper dries, it will resemble its original shape and size. However, the paper patterns do shrink after getting wet several times.

For instance, if you are working on a Worden lamp, where the same set of patterns is used six times, Glastar recommends making a second set of patterns. Use each one only three times. Better yet, make original patterns from a sheet of acetate or mylar. Unaffected by water, these sheets can be used over and over again.
