I saw a GRR-Ripper demo at Leevalley and liked it a lot until I found out I could not afford something that was so simple to make. I went home and came up with this little unit. I still need to put on some router pad on the feet.

Everything was out of scraps, 1/4” baltic birch for everything except the middle core which was some junk 3/4” MDF.

Sides:
(2pcs) 6.75” x 3” x 1/4”

Center Foot:
(2pcs) 6” x 1.5” x 1/4” glued together
(2pcs) 2.75” x 3/4” x 1/4” glued and braid to above

Body:
(Top) 4.5” x 6.75” x 1/4”
(Middle) 4.5” x 5.25” x 3/4” with LV 12K79.22 T-Slot cut into two 4.5” pieces.
(Bottom) 4.5” x 6” x 1/4”

One thing I like about this unit is you can move the center foot to the right and saddle your fence with the gripper giving you a 3/8” support right against the fence when ripping thin stock. I may add a side fence if I happen to need it but so far I have not.

I like. How is the back or end facing you supported? Is there another wing nut there also? Think I may try to make one of these if you don’t mind me copying your design.
Thanks for sharing

Simple and effective. Great idea to saddle the fence for ripping thin stock. Thanks for sharing.

Thanks all, I will take some measurements when I get back into the shop so you guys can easily duplicate it. The movable leg is attached with a 1/4” x 3/4” bolt and wing nuts to make it easy to adjust. Only cost me $1.50 to make as I only bought the fence handle.

Hello uMinded

Woaouh the best idea since a long time : Simple and very effective

I like it
In my favorite if I want my finger say to me : thanks !!!

You can add some sand paper under your piece for the grip or the special grip for skate board no ?

It’s just an idea …
Thanks for sharing

Great idea, skateboard grip is dirt cheap in sheets and its sticky backed already.

The Grriiper product is American made, a family run business and probably the best $79 you can spend for your shop. If you can at all afford one, I would encourage supporting that company over building your own. Or buy one and build a second. That’s what I did.

WOW! $79.00 for a push stick?? I’m too cheap to pay $7.95 for the plastic ones.
I tried one at a demo once and I really didn’t like the bulky feel … but that’s just me.

I agree with the “bulky” when its plastic but the same dimensions in wood feel “solid” lol. It does take some getting use to using as it obscures the blade while cutting but since its got legs on either side is safer than just a feather board and push stick. I got a GRR-Rip block on clearance missing the front flaps and I use them probably 50/50.

I’m favoriting this one. I agree with Chris’ sentiments about supporting American family businesses, to a point. $79 for a push stick is a no-go at least for me. And I’ll take wood over plastic every day! Part of being a DIY craftsman is being able to craft your own tools and jigs to get the job done, which is exactly what you’ve done with this design!

I bought 2 and it is some of the best money I ever spent woodworking

I do wish they were less money only so I could by more or lay around the shop like I do safety glasses so they are always within reach

I was sceptical about the Grr-ripper until I got one. I have a lot more control of the wood as I push it through while keeping my hands safely away from the blade. The ability to perfectly cut thin strips has also come in handy. I cant live without it now. I will say that it is over priced though. I got mine for 30% off with a 100% return policy, so I thought trying it out wouldn’t hurt.

I agree for the most part with supporting a domestic family business, but with the price where it is combined with the DIY mentality (we all have it here), I see nothing wrong with making one. I plan on making a wooden carbon copy of mine as a second in the near future.

I’ve had my grrr-ripers for quite a few years. There use to be a DVD magazine (short lived) that was one of the first to advertise and use them. I bought one very early one in the production of them. They really do help. Recently I added the additional hook to help and thing it’s money well spent. With the adjustable side “leg”, it allows you to have total control over wood.

Regardless of if you do it like this DIY, or simply buy the real thing, it’s a great idea and better than just a ‘push stick’ because the grrr-riper is actually a bit more useful than just a push stick.

I agree with SawdustTX.

I’ve been using push sticks more than 45 years and they have done the job safety for me. I’m all for making your own jigs and tool and projects whenever you can but if I can’t I’ll support American Made. Most of us look for ways to cut our overhead cost and this is a good and effective example.
Nice job on that “DIY GRR-Ripper” uMinded
