MICROJIGGRR-RIPPER GR-100 3D Adjustable Table Saw Pushblock, 2-Pack, Yellow

If you use a table saw, router or jointer these are an invaluable safety addition to anyone's workshop. They are easy to put together and easy to use. The control over your workpiece is significantly enhanced over a simple push stick, as is the peace of mind that there is now a large amount of protective material between a rapidly rotating piece of metal and your hands and fingers.I use a pair of these on a Bosch 4100-09 Table Saw and they work great! I am building a redwood potting shed for my wife and cut a number of boards this weekend. It took a couple of tentative cuts before I became comfortable with the necessary technique to get the most benefit and safety from these tools.I have a Bosch 1617EVS mounted in a Bosch RA1171 table and I have yet to try them, but I can foresee that I am going to have to either use featherboards or these, as well as remove the clear plastic bit finger guard.I HIGHLY recoomend these to everyone who works with table saw, routers, band saws and more.In response to one of the questions asked above: I believe that the question is specifically asking if the package includes the Micro Jig GRHB-010 GRR-Ripper Handle Bridge Kit as shown in one of the sample pictures. I just received my Gripper(TM) Deluxe package yesterday and it _does not_ have the Micro Jig GRHB-010 GRR-Ripper Handle Bridge Kit.UPDATE 15Sep16: I am building custom red oak wall and base cabinets for my den, both of which have doors with a top 4-inch rail which is arched. I am using the Yonico 12238 Rail and Stile Router Bits to create the rails and stiles. I succeeded in creating the rails and stiles for 11 wall cabinets doors; the stiles and bottom rails were easily routed using my Bosch 1617EVS router mounted in a Bosch RA1171 Router table, and four Kreg PRS3020 True-FLEX Featherboard (2 horizontal on the table and 2 vertical on the fence). Those parts came out beautifully; perfect routs with no sniping or burning. However, when I went to freehand rout the arched top rails, two top arch rails literally got away from me (flying at least 20 down the driveway...red oak has good hang time :) ), despite taking several shallow passes. After the second one got away from me (both top rail arches were ruined beyond repair), and after applying a band-aid to a badly scraped knuckle, I started to ponder how I was going to SAFELY rout these arched top rails. After much thought, I decided to use my GRR-RIPPER.I have the GRR-RIPPER Deluxe package, the GRGH-040 GRR-Ripper Gravity Heel Accessory, and a single Gripper 100 Upgrade Kit (although I could seriously use at least three more of these for various purposes). I normally use these on my Bosch 4100-09 Table Saw, and they perform amazingly.I rearranged various the components of the GRR-RIPPER to:1) Maximize contact of the rubber feet to the workpiece without contacting the router bit.This was achieved by moving the wide sliding piece towards the workpiece edge that I was going to rout, and using the large, flat piece with the hook (hereafter refered to as "stabilizing plate" from the Gripper 100 Upgrade Kit to brace the left side of the workpiece.2) Ensure that I had forward feed at all times for the workpiece compared to the angle at which I was approaching the router bitAgain the hook from the Gripper 100 Upgrade Kit "stabilizing plate" was helpful, but I had to be sure that the rotation of the router bit did not cause the workpiece to twist out from underneath the GRR-RIPPER, so I disassembled one of the GRGH-040 GRR-Ripper Gravity Heels, removed the small piece that slides on to the GRR-Ripper, turned around the Heel and attached it directly to the GRR-RIPPER. This aligned it more precisiely with the hook on the "stabilizing plate" and provided more support closer to the router bit.3) Ensure stability of the GRR-RIPPER on the workpiece as well as the router tableMaking sure everything was the same height while maintaining contact with the workpiece was easy due to a well-engineered product.4) SAFETY!I had to be certain that that I wasn't going to lose any more skin or blood, and I didn't want to waste any more wood with damaged pieces. It was critical that I maintained forward control while making a curved rout, without the workpiece twisting, slipping or flying away at high velocity, as well as maintaining all my digits.I assembled all of the pieces as described (see photos 1 - 3), donned my goggles and hearing protection, and nervously prepared to make my cut. Taking a deep breath, I powered on the router and began the first shallow pass...success! There was not one indication of movement of the workpiece other than how I wanted it to move. A couple more shallow cuts before the final pass resulted in a perfectly routed top rail (see photo 4...already glued up in the door, sanded, masked and ready for ruby shellac). The next ten pieces took less time than the first and involved _a_lot_ less anxiety on my part.Once again, the folks at Micro Jig have come through, proving that their product works on table saws, routers, band saws and more. The GRR-RIPPER and all of its accessories are invaluable safety additions to any shop, are amazingly flexible in terms of application, and add amazing value and safety to every project.Thank you Micro Jig for making my hobby safer!

What every woodworker needs or would use if someone gifted them. Excellent safety and accuracy device.

I am a occasional user of those lethal weapons called power tools. As a result I must "relearn" their use each time that I use them. I especially have a major concern over the use of my table saw since being made aware that a successful orthopedic surgeon acquaintance, and experienced wood worker, sliced off the tips of his forefinger and middle finger using his table saw, thus effectively ending his career. So when I encountered these GRR-Ripper push blocks on Amazon, and after reading positive posts on their design and construction, I figured that it was a no brainer to purchase them. I agree that they are overly expensive; but then again, they are about 1/10th the cost of an emergency room visit. These blocks are well constructed-- takes me back to a time when ALL tools were well constructed and not made of cheap steel or flimsy plastic! I suppose that there are viable alternatives to this product-- push sticks, or long blocks of wood-- I have read the posts of proponents of these methods. It seems that most of these alternatives are suggested by experience wood workers who have their own "pet" way of doing things and are quite good at what they do. But I feel that safety should never be compromised by procedures or use of tools that aren't the most safe ones available, especially by novice users. Accidents with power tools are just like wipeouts on a motorcycle-- its not "if" its going to happen, its just a matter of "when" its going to happen. I think that these push blocks add a major factor of safety factor to this dangerous hobby.

Well worth the money.

I feel much more confident using these with my table saw. Even with these still do not remove your riving guide/blade behind your blade. I bashed my index finger REALLY BAD from kickback because I had removed the riving blade and I wasn’t using any kind of push block. I am a weekend warrior. Now I have the riving blade always installed, use these push blocks and I even wear a face shield. Kickback is dangerous and happens before you even know it. I was lucky. My fingertip healed nice after a trip to the emergency room but I definitely damaged some nerves and have very little feeling on the top of that finger. BE CAREFUL AND CAUTIOUS. I know other people who have cut fingertips off.

These things are amazing and met all my expectations. I had to rip several pieces and these let me do that with speed and accuracy. First of all, these things are well made and the design is spot on. MicroJig obviously knows what they are doing when it comes to woodworking. Iam not a master carpenter or cabinet builder, but I have done enough to say that I am competent. I recently wanted to build a nice workbench and was using 3/4" MDF. These grippers made the job of ripping the sheets so much easier and safer!This is 100% my own personal opinion. I base my purchases on reviews of the product from others as well. I know that honest and helpful reviews provide insight to the company and to the purchasers as well. I am not connected to this company or any of the companies of products that I review. No monitory compensation was received and I was not required to write a positive review.

I should have purchased this years ago. This is a game changer when using a table saw, Safety is always first and this provides a safe way to cut wood on the saw. I purchased 2 and love using them. Makes cutting thin strips so easy and safe.
