MICROJIG GRR-RIPPER ZP9-B2S2 Zeroplay Miter Bar 2 Piece

I could have made my sled guides myself (and I still need to try this on my next sled) but these were at a fair price and I like how they can be adjusted to make the jig extremely square, snug and make your cuts very accurate and repeatable. Assembly instructions are pretty good and easy to follow. Prepping the rails themselves was easy, but building the crosscut sled was a bit more challenging. I manually measured for the 4” on center holes and drilled the 1/4” thru hole and then the 1/2” recess for the mounting screws, but two of the holes were ever so slightly off center by less than a 1/32” and, the jig is so snug by design, that it doesn’t leave much room for error on drilling the holes. In hindsight, I’d probably clamp the rails to the sled and use an awl to mark the holes so they are more precise. Live and learn! Anyway, I was able to make the two offending holes a bit more oblong and I was in business! These rails are very nice quality and easy to assemble as part of your jig or sled. I’m sure I’ll buy more when the time comes, as well as learning how to make some of my own! It’s a great product!

These are really great. Definitely watch a video about the setup. They really help.I bought two packs of these because I needed to make a 36" crosscut sled. I already have a 24" with an 18" steel bar runner. I looked for a longer runner, but nobody seems to make them. So I bought these, a little skeptical, particularly about the third runner entering the miter slot okay. The first two will start in the slot, but by the time the cut is finished, the first runner will be out of the slot and the third will have to enter. After I got it all set up, they work perfectly. No slop at all, and the runners don't even catch the least bit as they go in and out of the slot.Since I used 15/16" MDF for my sled, I bought 1" knob screws from the hardware store along with fender washers. Then I countersunk 1" holes for the washers. It's much better than the screws and washers that come with the slides.I used three for the main sled, and the fourth one I used to make a zero clearance stationary sled for the right side of the blade.Like others have said, the slides are very well conceived and made. Some complain that they are expensive, but for the quality that these are, the price is just about right. We'll see how they hold up, but I think as long as don't abuse them, they should last a long time.

I would have given this a "5" except it didn't fit my table saw. In fact, it didn't fit anything in my shop with the name RYOBI on it. Nor did it fit anything I have from HARBOR FREIGHT! It's just a hair too wide. Which is what I get for buying cheap tools. But when you live on an allowance provided by your Uncle, and never increases more a few cents a month no matter what inflation is doing, you tend to keep costs as low as possible. So this is a great product and would add value to my cheap tools, if it were just an RCH narrower.

The only complaint I have is they are expensive. They do perform better then I expected and zeroplay means zero play in this case. If I hit the lotto I would buy them again and I recommend them for the person that wants the more perfect cut on a table saw. I have not used them on any other shop equipment / tools. Arrived on time, packaged well, easy to install and adjust.

My only complaint is that they are a bit short., but the system works well. Had a sled completed in less than 30 minutes.

I have most of the Micro Jig products and I think they are some of the finest tools out there. The GRR-Ripper is probably the best tool I have ever seen for saws, routers, etc. Very innovative. I bought these bars and stops with the intention of making some custom jigs in the future and wanted to use the stops in combination with some hold down clamps. These stops are ONLY designed to work in a full size T slot and will not work in a normal 3/4" miter slot as I was lead to believe. So basically the stops are useless to me. It's the only product from Micro Jig that has not thrilled me so far. I wrote to their sight and they were very helpful and supportive, but in the end, it just isn't going to work as shown in their video.

this is my second set. I build oversized, heavy furniture and I am constantly upgrading my table saw slide/sled. As an Engineer I am very OCD that my 90 deg angles... have to be 90 degrees.. not 88.. .not 92... but 90 +/- 0.5.I used to make my one bars our of hardwood but couldn't really get a nice fit. They would work fine the first few times but then wear out and there was a slightly little play to each side which I was fixing with tape to increase the width by mils. \these ZEROPLAY are amazing. follow the instructions. use a nickel and a thickness gauge and you don't have to worry. my sled is 4ft long x 2.5ft wide. and I used specialty extruded aluminum as the fence with a wooden backup at the saw cut line.Highly recommend these miters bars.22JUN17 UPDATEI STILL LOVE THESE... I NEED ZEROPLAY TO BUILD LONGER ONES THOUGH - JUST TO FIT MY NEEDS! :)

Setup in your mitre slot is extremely easy. You’ll be in business in 90 seconds. Building a sled is far more time consuming but not impossible if you take your time and have some basic woodworking skills. The included directions give you basic plans for a sled but using your imagination, the possibilities are endless.Having a drill press and the necessary forstner bits are almost a must for building a sled which I didn’t foresee when I purchased these. Just another reason to buy more tools to the wife’s dismay.For my sled, I used 3/4” cabinet plywood and glued on a 3mil PVC sheet which makes gliding on the table surface smooth as butter. I bought an extra handle for my GRR-Ripper and used that for extra control. I painted the finished product and plan on adding a plexiglass guard to protect against any possible kick backs.Overall, a great and well thought out product and definitely recommend.
