Jerry and Phil,
You should both watch the Grripper demonstrations on Youtube or buy Micro Jig's DVD to learn how to use them properly.
The Grrippers aren't intended to be used the way that you plan because there is no part of the Grripper that is holding down the piece of the stock that's between the blade and fence. This is the piece of stock that will give you kick-back if you don't hold it down during the cut. The fence will hold the offcut against the blade and as soon as the off cut is cut completely free from the stock, the friction of the blade rubbing against it will lift it up to the blade teeth and then the teeth will throw it at you.
Micro Jig makes a side piece for the Grripper that is 1/8" wide ,so it can handle cuts down to 1/8" with this side piece installed. But the way the Grripper is shipped, it only has 1/4 and 1/2" sides, making 1/4" is the narrowest cut that can be safely made using it. You will need to buy and use the 1/8" side piece for one side of the Grripper to cut strips between 1/8" and 1/4". If the piece being cut off the stock is narrower than 1/8", you should be using a thin strip ripping guide instead of the Grripper. To avoid kick-back you should always have a way to hold down the stock on both sides of the blade, and a way to push both pieces of stock completely through the cut.
To be certain that the Grripper is positioned properly for narrow cuts it's best to position it on your stock and against the fence, then bend down and look under the Grripper to see where the blade will be cutting, then decide what adjustments need to be made to the Grripper to be certain that it will be holding down both the stock and the off cut without the Grripper being damaged by the blade as you make the cut. The center piece of the Grripper will need to be moved frequently if you are doing rips of varying widths and you may need to occasionally make adjustments to it to keep it out of the blade path. With the Grripper on the stock to be cut and against the saw fence, with the fence set for the width of cut sight through the bottom of the Grripper before you make the cut to be certain certain that the position of the Grripper can hold down both the stock and the off cut. This is the time to make any needed adjustments before you begin the cut.
A Grripper isn't intended to be used like a push stick and it will greatly increase table saw safety if you learn to use it correctly. Having two Grrippers lets you use them hand over hand when feeding long stock, while holding down both the stock and the off-cut and feeding them forward continuously.
It took me a while to get comfortable with my Grrippers, but my problem was the mental block that I had planted in my head from over 50 years of woodworking. This mental block was so strong that it still makes me hesitate when I'm about to make a table saw cut using my Grrippers. My mental block is "the 6" rule". This rule simply states that "Thou shall never allow fingers or body parts to get closer than 6" of the spinning blade". This rule has kept me safe for 50 + years and I have no scars to show from table saw use. When I use the Grrippers the way that they are designed to be used, while holding the handle of the Grripper, my hand passes only about 2" above the blade. That old 6" rule gave me fits, until I managed to convince myself that while holding the handle of the Grripper there was a heavy piece of plastic between my hand and the blade teeth, and this made it OK. I still hesitate each time because of that old 6" rule, but I can get myself past it to use the Grrippers and do it safely. Please watch the videos and learn how to use the Grrippers properly.
