GRR-RIPPER - What do you think?

I viewed a couple of videos at http://www.jointech.com/gripper.html on a
push jig called the GRR-RIPPER. Whenever I see a commercially made gizmo
like this, I try to figure out how to adapt the ideas to something I could
make for myself. But there are too many nuances in this one to consider
making it myself. This device could be viewed as ingenuous or another
widget whose time will pass as another fad.

I'm never thrilled with anything that depends on working over an exposed
sawblade, but some of the cuts in the video could not be made any other way
(that I know about).

What do you think?

Bob

I bought one recently and have only used it 3 or 4 times. Like Larry, I
used it to cut narrow strips - in my case to make 1/4" thick banding for
some cabinetry. In the past I would have indexed the table saw fence, and
moved it incrementally as I cut the strips off a wider piece. With the
Grripper, it saves a LOT of time for these operations, and since you're not
moving the fence all the strips come out exactly the same without any trial
and error.

In my case I only have one of the units, but I was cutting on a board about
7 feet long. I didn't use the Gripper until the last 2 feet or so and just
fed the rest of the board by hand. I don't really see why this is a
problem, and I don't think I'll ever buy a 2nd one unless I damage the first
one.

All in all, I'd say this gives the user a lot of control and allows you to
make these otherwise tedious and/or dangerous cuts safely and quickly.

I use mine whenever I'm cutting narrow strips or short length pieces. You
do need two of the things when you cut pieces longer than about 18 inches.
Below is one way I use it.

I have one that I used to cut narrow strips for a mission-style coffee table.
Very good for that purpose--I wouldn't have wanted to cut those strips without
it. It is expensive, and I damaged one while using it, requiring an expensive
replacement part. All in all though, I thought it was worth it.

Yea. Me too. Looks like a good idea, maybe.

Just how narrow can you cut with the thing?

I just recently acquired a table saw. Been using a RAS for about 30 yrs
and made a
"device" to hold material to "rip" narrow peices on it, up to the
"crosscut" limit
at least.

After having seen the online video of this, I'd definetly say its worth
the money, and not worth trying to copy.

I don't have one, but I too would be interested in hearing some comments.
It certainly does look interesting, and if it works well, would be a
valuable addition to the workshop.

Not having a table saw myself, I could simply not have a clue what I'm
talking about, but what happens if it slips and the thing hits the
blade? I know it has rubber nonslip pads, but that doesn't always
guarantee you won't accidentally lean on it hard enough to push it
into the blade.

I've had one for a year and a half. I use it a lot. I think it's a
good deal, but pricey! But then I do a lot of cutting of small pieces
and not many large construction projects. I feel a lot safer using
it - - - -so I use it! My hands/fingers are worth a lot to me.

The video shows the user ripping 1/4" strips without any trouble.
Impressive.

Pricey, but worth it to me. I reach for mine a lot for those narrow cuts.
Easy to set up and change as you go.
Just wipe the rubber grips clean of dust every now and then. Damp paper
towel works for me.

It's made out of fairly tough plastic. I would think that if you were to
push it into the blade, it would protect your hand fairly well. You'd
probably have to buy a replacement grr-ripper, but that's far cheaper
than a new hand.

I bought one on sale at Rockler, and love it for cutting small parts.
My only wish is that it would have some sort of drop down tab to catch
the back of the work piece. It's never slipped on me yet, but the extra
assurance would be nice.

Seem to me a 2x4 scrap with a piece of rubber will do the same thing and
will not limit you to 1/4" and larger rips. IIRC cutting narrower than 1/4"
cuts the jig.
