Omni-2 Plus+ Wire Saw
Frequently Asked Questions
1. How do I choose the saw that is right for me?
The Omni-2 Plus+ cuts in any direction and is virtually maintenance free. It is the most economical saw in its class. It trades speed for simplicity, so it is somewhat slower than other saws, but not enough so to be distracting. You will be able to cut your patterns easily and in a modest amount of time.

2. Is there a video showing the setup and use of the Omni-2?
Yes. Follow this link to view the video.
3. What is the easiest way to install a new blade?
Some people encounter difficulty installing a blade for the first time or into a new chuck. This is because a new chuck tends to be tight, and it can seem difficult to push the blade into place. If you are installing a blade for the first time, and you experience difficulty in pressing the blade fully into the chuck, you may find it easier if you complete remove the nut from the chuck. Place the blade at the tip of he chuck, and loosen the nut and allow it fall down the blade. You should find at this point that the fingers of the chuck can be moved more easily to allow the blade to be inserted. Once the blade is in the proper position (with a little of the red portion outside of the fingers of the chuck), you can bring the nut up into place and tighten it. Do not tighten past the end of the fingers. If you are installing a new chuck in a saw, it is a good idea to insert a blade into the chuck a few times before you install the chuck into the saw. This will make it easier to install the blade later.
4. What is the best way to mark the pattern before I cut?
As you undoubtedly have or will discover, the glass gets wet when you use a diamond saw. For this reason regular markers, such as Sharpies, quickly wash away. There are markers available that use paint rather than ink, and these are well suited for marking patterns on glass. The most popular of these seems to be the Pilot Extra Fine Gold and Silver Creative Marker. We have found these at our local Staples, and Office Depot has something similar. You can also copy your pattern onto overhead transparency material and glue or tape the pattern to the glass. Your stained glass dealer can probably recommend some commercial products that can be applied over a regular felt marker lines to improve their resistance to water. In a pinch, you can use Chap Stick or Vaseline.
5. How do I reduce the vibration?
The blue washers that you saw as you assembled the saw are special vibration washers. If you are experiencing too much vibration, it is likely that these washer were compressed too much and are not doing their job. The solution is to loosen the two screws that attach the top of the saw to the base.
6. How can I increase the flow of water to the blade?
Poor water flow is usually the result of either air or debris in the hose. You can use a small squeeze bottle of similar object to draw the air bubbles or debris though the hose. If your pump is old, it may be worn out and a new pump can be ordered at low cost from Gryphon.
7. How can I reduce the flow of water to the blade?
You cannot really have too much water on the blade, and although you may find it distracting, we encourage you not to reduce the water flow. Water cools the diamonds, allowing them to cut better and last longer. If you feel that you must reduce the flow of water, you can use a spring clamp on the hose to restrict the flow. Be sure to keep a close watch on the blade as it cuts to make sure that it remains wet.
8. What kind of oil should I use when lubricating the two round shafts?
You should use the lightest possible oil: either clock oil or sewing machine oil. Never use 3-in-1 oil or spray lubricants such as WD-40. These latter lubricants contain additives that gum up when hot, and actually turn into a glue that will cause a sticky mess on the shafts.
9. How do I tell if I need a new pump?
The pumps wear out after a while, due to the constant movement of the blade inside the pump. If you experience a gradual descrease in the water flow, you should be able to restore full performance by replacing the pump. Put about an inch of water in the base before you remove the pump to soften the glue-like glass dust. Use a pair of pliers to pull out the old pump. The pump pulls straight out (like a cork). There is a ring around the pump that is the same color as the pump. You will need to save the ring for the new pump.
