Because I am ripping thin parts in this demo and the riving knife opening on the throat plate is wide enough for the thin parts to fall in and catch. Since the rip side is only 1/4" or so and I am ripping short parts, there is NO chance for the kerf to close and pinch the blade. The thin rip is simply too narrow to exert any force to pinch the blade. Having the thin rip fall into the riving knife opening at the back of the throat plate is a much bigger risk.
4:04. looks like you cut into your quarter inch leg there. Plus we all know the demos are for short boards once you start getting longer and now you have to buy two of them and do the hand over hand technique that's getting up there in price. So really if you only wanna buy one you need to put it on the wood at the very end once it's ready to finish up through the blade
Don't position the 17:27 stick next the rip fence. That can cause a kickback. The push stick should be positioned so that it runs parallel as close to the blade as possible. I have a grr ripper and it is a great tool but your video is somewhat deceiving. The cut could be made safely either way. Also, I am not seeing a riving knife. Lack of a riving knife can cause kickbacks.
Pat, if you are referring to 07:27, the 1/4” cut as shown is perfectly safe. The only possibility for damage is to the legs of the GRR-RIPPER. There is no riving knife since I am cutting 1/4” strips and the riving knife opening on the SawStop throat plate is wide enough for the thin strips to get caught. Ripping a 1/4 by 3/4 strip into two pieces leave no material to be able to pinch the blade and kick back. There literally is not enough wood to move.
Yeah! Super excited about the new stops. Thank You😊
Thanks Ralph, enjoyed chatting with you at the Hartville Hardware Tool show.
Always a great show at Hartville, glad to talk with you too.
I have two older GRR-RIPPER that I need to upgrade with SafeRip kits.....glad the system has been kept upgradable.
Awesome products as always. Looking forward to working with you in 2025
Why don’t you have a splitter or riving knife on the table saw behind the blade?
