1. Getting Your Grinder Ready

You must first remove the current set-up on your TwinSpin™, Impulse™, or WizCG™ including all work surfaces, reservoirs and bits You should have only the main grinder body. Refer to the exploded view during assembly.

Page 2

2. Setting Up the Work Surface

Locate the reservoir drain stem on the bottom back of the white reservoir / work surface (A). Attach one end of the plastic drain tube to the stem. NOTE: Placing the plastic tube end in hot water a few minutes makes this easier. Place the large white reservoir / work surface (A) on the grinder body. Secure in place with the T-lock pins (D) by inserting and turning to the 'lock' position. Press the pin covers (E) in place. Put the white reservoir cover (B) in place. Set the white mini-beveling work surface (C) in place over the larger reservoir / work surface. Place the other end of the tube in a container to collect excess coolant.

 

 

3. Setting Up the Coolant Feed System

Insert the wire stand (N) into the stand supports on the back of the main grinder body. Attach the clear feed hose to the stem on the underside of the white coolant reservoir (J). NOTE: Placing the plastic tube end in hot water a few minutes makes this easier. Attach the coolant hose holder (L) to the front of the reservoir using the thumb screw and nut (M). Feed the end of the hose through the coolant flow adjustment screw nest and attach to the stem on the back of the coolant hose holder. Insert the nylon flow adjustment screw (K) into the threaded brass hole on the front of the coolant reservoir. Hang the reservoir on the stand. 

Setting the Bevel Width

1. Process Overview
The beveling process involves setting the bevel face width; grinding the initial face; grinding the final face and then polishing. The initial face width made with the coarse wheel is slightly short of the final width. This allows the fine grit wheel to remove the deeper scratches and put a more uniform, frosted finish on the bevel face before polishing. Both the coarse and fine bevel wheels have built-in stop rings so you don't over-grind the face. The beveling wheels must stay in the same position on the motor shaft as you change from coarse to fine. The adjustable brass adapter lets you set the width of the bevel and then maintains the correct wheel positions as you change from coarse to fine.

2. Setting the width of the bevel face.

a. It is extremely helpful to tape off the width of the bevel face on your glass or stock bevels before beveling. It serves as a visual guide when setting the bevel width and protects the rest of the glass from being scratched while beveling. Use a good scotch tape, water resistant tape, contact paper or etching resist.

b. Place the brass lifter / adapter (H) onto the motor shaft and align the set screw with the flat side of the motor shaft. Do not tighten the set screw at this time. Place the fine wheel (G2) onto the adapter but do not tighten to the adapter at this time. Always use the fine wheel to set the position of the adapter.

c.Most stock bevels have a 1/2" bevel face. The bevel width gauge included has a 1/2" and 3/8" setting face. The gauge is used to set the position of the adapter and wheels. Place the beveling gauge flat against the work surface with the desired face width facing down toward the beveling wheel and the edge of the gauge against the stop ring. Make sure that the gauge sits on the higher and wider portions of the surface and not in a drain channel.

d.By turning the screw at the top of the adapter you can raise or lower the wheel. Adjust the wheel position until the diamond surface completely rests against the face width portion of the bevel width gauge. Make sure that as you adjust, the edge of the gauge remains against the stop ring on the beveling wheel.

e. Now lift the adapter and wheel off the motor shaft making sure not to disturb the position of the adjustment screw. Remove the fine wheel and put the adapter back onto the shaft making sure that the adjustment screw comes to rest on top of the motor shaft. Secure in position to the flat side of the motor shaft by tightening the set screw. The adapter is now in correct position for both wheels and will remain in this fixed position through the beveling process.

Beveling

Step One - The Coarse Wheel

Slide the coarse wheel (G1) onto the adapter and secure in place by tightening the set screw to the flat side of the adapter. Insert the two white sponge pins (Q) into the holes in the back of the mini-beveling work surface. Dampen the yellow sponge (O) from the 'Rough Cut Beveling Wheel' bag and place it over the pins and behind the wheel as shown. The sponge will help control over-spray. Fill the coolant reservoir. Position the end of the coolant hose holder so that coolant drips onto the beveling wheel just to the left of the stop ring as shown. Adjust the drip rate by turning the nylon flow adjustment screw (K) to provide a steady, continual drip that keeps the wheel wet while grinding. NOTE: If you notice a white paste or powder anytime while grinding, increase the flow of coolant onto the wheel and check the coolant level in the reservoir.

1. Hold the glass flat against the work surface and begin feeding it into the wheel using a back and forth motion. This helps you grind evenly across the piece. It is important to keep the glass flat against the work surface as you grind so you grind to a uniform depth across the entire piece of glass.
2. It is very important not to force the glass into the wheel. Let the diamond do the work. Using excessive force may leave scratches too deep for the fine or polishing wheels to remove. Continue grinding the face until you reach the stop ring. CAUTION: Do not run the glass into the ring. This can chip the edge or cause the glass to break.

This is what a good coarse ground face should look like

Step 2 - The Fine Wheel

Turn off the drip feed. Remove the sponge and coarse wheel. Remember -- the adapter stays in place! Place the fine wheel (G2) onto the adapter and secure in place to the flat side of the adapter. Rinse out the sponge and replace as before. Check the position of the coolant drip and set the drip rate to a steady, continual drip. Use a lighter touch and the same back and forth motion as you feed glass into the wheel. Continue grinding until you reach the stop ring. Make sure that you maintain an adequate supply of coolant to the wheel. The fine wheel not only grinds the final bevel width, it also removes the coarse surface created when initially grinding the bevel face.

It is extremely important that you have a uniformly thick, smooth, frosted finish across the entire bevel face before proceeding. Taking time now will make polishing that much easier!

Step 3 - Polishing the New Bevel Face

When the bevel face is a straight line or outside cure, the 5" disc is the fastest and easiest to use for polishing. An inside curve requires the smaller inside curve polishing wheel (optional). The grinding process leaves a series of tiny parallel ridges and valleys on the bevel face. Polishing pushes the ridges into the valleys to create the smooth, clear polished surface. Polishing involves creating enough surface heat in the glass to accomplish this without heating the glass to the point it fractures. It is extremely important that you always keep the polishing pad wet with coolant. Resting a finger on the glass helps detect the build up of heat. Practice on scrap first to develop a feel for the polishing process and know when to let up and let the glass cool before continuing.

Polishing with the 5" Disc

Remove the sponge, fine wheel, adapter, mini-beveling surface and the white disc reservoir cover. Clean out all grinding residue from the previous steps. Install the 5" polishing disc (I) so it sits about 1/8" above the work surface. Position the coolant hose holder so coolant drips just to the left of the wheel hub. Fill the reservoir. Insert the two white pins (Q) into the holes on the disc surface. Place the yellow sponge (P) from the 'Polishing Wheel' bag over the pins in front of the 5" disc as shown. This will help contain over-spray. Mix up the polishing compound by filling the bottle with water to 1/4" above the label. Shake well to insure thorough mixing. Use the sponge brush to apply compound to the entire wheel. Adjust the coolant drip rate to a steady drip onto the disc.

1. Turn on the machine. Holding the glass securely, place the newly beveled edge flat on the wheel so the wheel rotation is perpendicular to the direction you ground the beveled edge. You want the disc to rotate into the grooves, not parallel to them. Working in the same direction you ground the edge will not polish! Polishing involves creating enough heat to cause the glass to flow from high areas to low creating a level surface. Make sure you have a firm hold on the glass. The spinning disc has a lot of forward momentum. The friction between the glass and the pad creates the heat needed to polish the surface. 

 

2. Put downward pressure on the glass while moving it slowly back and forth across the disc, keeping the face in contact with the pad. Alternately increase pressure until you feel the glass get very warm then decrease the pressure or remove the glass from the surface and allow to cool slightly. NOTE: Keeping your finger against the bevel during polishing lets you feel and monitor the temperature of the glass while polishing. Do not use so much pressure that you stall the disc! Periodically re-apply additional polishing compound to the bevel face. It is extremely important that the polishing disc is always wet. A dry surface won't polish, can cause the glass to heat crack and will damage the polishing pad. 

 

3. Keep polishing until you have a clear and scratch free surface. Remember, polishing takes both time and practice! Most of the time spent making a beveled edge is in the polishing step.

Polishing with the Inside Curve Wheel

The optional 2.5" polishing wheel is needed to polish inside curves which cannot be done on the flat 5" disc. Although you can polish straight line and outside curve bevels with it, it is easier and much faster to use the 5" disc for those applications.

The setup for using the inside curve polishing wheel is the same as for grinding the bevel face. Place the inside curve wheel onto the adapter and place on the motor shaft. Adjust the position of the wheel so that it sits about 1/8" above the mini-beveling work surface. Carefully remove the polishing wheel, secure the adapter to the flat side of the motor shaft, then replace the wheel onto the adapter and secure to the flat side on the adapter. Fill the coolant reservoir. Position the coolant hose holder to drip just to the side of the wheel hub. Place the yellow sponge (P) from the 'Polishing Wheel' bag over the pins behind the disc as shown. This will help contain over-spray. Mix up the polishing compound as instructed on the bottle. Shake well to insure thorough mixing. Use the sponge brush to apply compound to the entire wheel. Adjust the coolant drip rate to a steady drip onto the disc.

1. Turn on the machine. Holding the glass securely, place the newly beveled edge flat on the wheel so the wheel rotation is perpendicular to the direction you ground the beveled edge. You want the disc to rotate into the grooves, not parallel to them. Polishing involves creating enough heat to cause the glass to flow from high areas to low creating a level surface. Make sure you have a firm hold on the glass. The spinning disc has a lot of forward momentum. The friction between the glass and the pad creates the heat needed to polish the surface.
2. Put downward pressure on the glass while moving it slowly back and forth across the disc, keeping the face in contact with the pad. You may have to work different sections of the glass or change the angle of attack depending on how tight the curve is. Alternately increase pressure until you feel the glass get very warm then decrease the pressure or remove the glass from the surface and allow to cool slightly. Do not use so much pressure that you stall the disc! Periodically re-apply additional polishing compound to the wheel and bevel face. It is extremely important that the polishing disc is always wet. A dry surface can cause the glass to heat crack and will damage the pad.
3. Keep polishing until you have a clear and scratch free surface. Remember, polishing takes both time and practice!

Trouble Shooting

Below is a list of common problems and possible solutions. Remember that beveling is an art in itself and takes some practice. Being patient and not rushing through the steps will soon make you an expert beveler!

Problem: I can't get a final polish on the bevel; there are still scratches.

1. You didn't use the fine wheel long enough to smooth out the rough cut face. You can go back to the fine wheel, re-grind the face and then polish.
2. You didn't grind the bevel to a uniform thickness and left high and low areas on the face. Use the fine wheel and light pressure to even out the face and then polish.

Page 7

3. You used too much pressure when grinding the bevel face and created scratches too deep to remove. Use light pressure against the diamond wheels when grinding and let the diamond do the work!
4. You didn't have enough coolant to keep the wheels wet while grinding. Improperly lubricated wheels allow the diamond to dig into the glass; let grinding residue stay on the wheel and make deep scratches on the face and prematurely wears out the diamond, especially on the fine wheel. Increase the drip rate of coolant while grinding.
5. You didn't use enough pressure while polishing. You need to let the glass become very warm. Try increasing downward pressure (without stalling the disc). Make sure the entire bevel face contacts the pad and moving back and forth more slowly. Be patient.
6. You didn't apply polishing compound. Make sure you coat the disc before starting to polish. The porous nature of the pad holds compound. Increase the frequency you apply compound to the pad and bevel face. Apply compound as you would paint on a wall. To apply excess amounts only wastes compound. When you can't see any whitish slurry under the bevel face, it's time to re-apply.

Problem: The glass cracked when I was polishing.

1. You allowed too much heat to build up in the glass causing it to heat fracture. Try reducing the pressure you are using; move the glass back and forth a little faster or allow it to cool more before continuing.
2. You aren't keeping the pad wet enough while polishing. Increase the drip rate or add more polishing compound to the disc surface. The polishing pad needs to remain wet during the polishing process.

Problem: The new beveled edge doesn't seem to match the other edges of my stock bevel.

1. You didn't set the initial width correctly. Make sure you use the fine wheel when setting the position of the adapter. If your face is just a little narrower you can loosen the set screw on the adapter; raise it slightly; re-secure; and then widen the face using the fine wheel. If you're quite a bit short, go back and repeat the steps for setting and grinding the bevel on page 3-5.
2. Stock bevels are machine ground and polished. Different machines make different face widths, degree of bevel, and each manufacturer has their own standard for acceptable end product. If you don't get a perfect meet, you will have to determine whether it's better to under or over-grind the bevel depending on its intended use. A standard beveled edge is 14⁰, which is what the wheels in this kit produce.
