Grr-ipper

Gr ripper is highly touted as the ultimate safety device to use on a table saw. Aside from SawStop. I would like to know if any LJ's have had a slipping problem? All that I read is that it is great but a little expensive. I did read the blog about a kick back incident but nothing more. There is nothing more important than shop safety and regardless of the cost is this the item to add?
Thanks

I think safety is important enough that I have a SawStop and an Excalibur overarm guard, but I don't see the need for a GRRRripper.

I'm a big believer in purpose made consumable push devices. They're super fast and simple to make, and pretty much free, made from plywood and MDF offcuts. Most are various iterations of notched blocks, often where the blade is allowed to cut into them. As they pass directly through the cut, they fully push and hold down both the keeper and scrap.

Most are simply a suitably sized rectangle with a notch along the bottom. I don't bother shaping them, cutting handles, etc…

Here's an example from the web:

I agree with Barry. With a decent sized pushstick, the worst that could happen is the saw flies it out of your hand, and your hand is already above the saw blade, so not too bad if you stay to one side as you should. I can't see how a GRRRipper could possibly hold a piece of wood that is totally in reverse due to a 2 or 3HP motor turning a saw blade that has caught.

GRRRRIPPERS are GRRRREAT …but, until you try them for yourself, you will probably remain a skeptic.

True, they can't hold a piece of wood that is in a kickback situation … what they WILL DO is give you absolute control of the piece to prevent the occurrance in the first place.

Barry said the magic words as far as I'm concerned.
Purpose made CONSUMABLE push devices.
You get the best control of the wood and the blade, when near your hand, is completely covered by the pusher.
Mine look sort of like a shoe.

I like the idea of the grippers - so much that for the past few years I've been meaning to make some… but I simply find myself using a scrap piece of wood from the cutoff bin/trash and usually use that and don't worry about cutting into it or what not…

maybe one day…

Remember, the best prevention of kickback is not a push device at all, but a properly installed riving knife.

If the rising teeth on the rear of the blade can't get a decent grip on wood, kickback is physically impossible.

If the rising teeth get a good enough grip, on a saw with decent horsepower, the board is leaving like a Navy jet on a catapult, regardless of what's in your hand.

The thing about the GRRIPPERS is that they give you confident control of your stock in many applications … they are not limited to ripping on a table saw … if you've never used them or viewed them in use, you will never understand their full potential.
