Topic tags/keywords: question jig tablesaw sawstop

I hope I am posting this question in the right forum. I am very new to woodworking and I am working in a vacuum. We live on a ranch in a very rural area and my only contact for questions is over the internet. I have a SawStop table saw and my husband purchased me a Microjig Grr-Ripper for Christmas. I just unboxed it and have not assembled it yet, but I have viewed the accompanying DVD. It appears to me that in order to use the “Gripper” I would need to remove the riving knife (as well as the blade guard). Does anybody else have a SawStop and have experience with the Gripper? I’m just unsure if I should in fact remove the riving knife (how safe is that?) and if I should even keep the Gripper. Input is welcome.

Thanks, CTW

I don’t have a Grr-ripper so I’ll leave that to people who do.

But I do have a table saw and I would caution you about removing the riving knife and the anti-kickback pawls. The SawStop will probably keep you from cutting off your fingers. But it won’t do anything to prevent kickback. That’s what the splitter and pawls are for.

Just my two cents.

You need to remove the blade guard but put in the riving knife when making rip cuts less than the whole width of the gripper. Or you can just use the riving knife and no blade guard all the time. The safety device should protect you in case of a mishap. The gripper should prevent any mishaps.

Since the riving knife moves up and down with blade height, there is no reason to remove it. For a standard through-cut, there shouldn’t be any problem.

The blade guard on the other hand, needs to be removed, as it will get in the way of the Grrripper. For this reason, I very rarely use my Grripper.

Thank you to everybody who answered. I will go out to the shop tomorrow and spend a little time looking at this.

I think you’ll find the riving knife just a hair shorter than the blade. That may vary depending on the blade, but on mine it’s maybe 1/16” or so shorter than the blade. You will have to remove the guard, but other wise the gripper should work with the riving knife in place, obviously the blade can’t be too high for that.

As others have said, the guard needs to be removed to use the Grr Ripper. The riving knife should still be used and is compatible with the Grr Ripper. I use my Grr Rippers all the time with the riving knife.

As others have said you can’t use the guard for obvious reasons, but I used mine on my sawstop for about 6hrs yesterday and worked just fine with the riving knife in place. My feet are killing me but they worked just fine.

I’ve been using two of those for years and love em. !

Just a quick note to thank everybody. I did go out and take a close look at the saw and realized I had the total blade guard installed instead of the riving knife. And yes, the riving knife did track to the blade height. So that mystery is solved, but I have many more.

Thanks, CTW
