ROCKLERJIG IT Shelving Jig & Self Centering Drill Bit Set – Drill Guide Jig Ideal for Adding Shelves to Cabinetry - Cabinet Jigs – Kit Includes JIG IT Shelving Jig, Self Centering Bit & Hex Wrench

I bought this to bore holes for shelf pins in a custom master closet. Mainly, I needed something reasonable to speed the task up. Looking back, it totaled up to over 1800 holes.While this isn't a high-end jig with lots of features, it did a decent job maintaining my hole spacing. My application already had the shelf-support walls, so I had to drill these in place.However, I feel I should warn about a few issues:* You can get 11 holes in a row from this jig. I wish I could have had a few more, but this wasn't that much of an issue.* The indexing hole that holds one of your pins (helps to maintain an constant spacing when having to move the jig up the line for the next run) does not hold your pin very snug- this can be an issue when you're trying to hold the jig steady with one hand and drill with the other in situations where clamping isn't an option.* The screws that attach the lexan plate to the raised black, plastic rail sit proud of the plate. This wasn't the biggest deal, but still a less-than ideal setup.* When used with typical plywood (as opposed to hardwood, which I haven't tried this with yet), the drill bit does not pull all of the wood shavings from the holes. It does pull some, but not all. - This presents a problem in that the sleeve will sometimes not spring back into place all the way because it will get clogged. This can require you to pull the jig off the work while you do a quick pump of the sleeve, and then put the jig back up. - I ended up with 85% of holes having shavings left inside of them. Most of these shavings aren't loose enough that you could just blow them out, so I first started digging them out with a nailset (best option available at the time). I eventually figured out that the simplest method was to insert a pump needle, like you use to blow up a football or soccerball, in a blowgun kit on my air compressor. This required on a few seconds per hole to get them all clean, as opposed to 20-30 seconds.All of these were issues that can be overcome, and for the price, the hassle wasn't a big deal. If you plan on using this jig for daily use, you may want something slightly more durable- I can see where the lexan has worn slightly where the sleeve would rest around the hole.I'm happy with the results so far.

Had seen the product used on New Yankee Workshop and thought it would be a good jig to have. Have used peg boards in the past to do the shelf holes. It works, but left something to be desired. The day my jig arrived, I was building some upper kitchen cabinets and had just finished a small pantry cabinet. All these cabinets needed the adjustable shelving. In the past this process for me would have taken about 2 hours to have done, with all the measuring pencil marking and double checking. Then making sure the tape was at the right depth on the drill bit, and rechecking every few holes. With the Rockler Shelf Jig all I needed to do was to find my center points on the front and back of the sides and line up the marks on the jig itself. Next I had to decide which row (A or B) of holes to use. The jig works great with either framed or frame-less cabinets. The jig was very easy to assemble with the 3 screws supplied. The self-center drill bit made short work of getting the holes centered and aligned. Once the cabinets were hung and the shelves placed, a level was placed on the shelf and it was level. This has been the best jig I have obtained lately. I will be using it to finish my kitchen redo and then the new workshop/garage cabinets.

I needed to make several shelf pin holes in a custom shelf/cabinet that I was making out of melamine boards. For the most part I really like it. Saved me a ton of time in measuring. It's so easy a caveman can do it! All you have to do is make sure the surface is flat and square it up against the edge and just drill. What I do to keep it consistent is drill one hole and then using a shelf pin in an indexing hole drill the rest to keep it straight and repeat. Tested to see if they were straight with some shelf pins and a board; straight as an arrow. In terms of quality, I didn't really notice it being that cheap. Maybe the black plastic bar is a bit thin, but the acrylic indexing board is pretty sturdy. My only issue is the aggressiveness of the spring on the drill bit. It springs up fast if you try to go too fast and it will chip around the hole a bit. Using melamine you can tell right away, but since I'm going to cover the unused holes with plugs, not a huge deal. I tried the tape method, but it did not work. Going slow helped a lot more. I definitely recommend this if you do small projects here and there. Works like a charm and it's dead on accurate. Just be careful drilling on softer stuff. Tends to chip. 4/5.

I have a similar product from another manufacturer that is not as convenient to use as this JIG IT, and bought it to work on already build cabinets and longer cabinets and shelving where many holes need to be drilled. I like the overall approach to the item, but the drill bit/shank assembly will hang up in the sleeve if not adjusted exactly right. I would like to see a reengineering of that. Otherwise, it is convenient to use.

I purchased this to use on a custom built desk/bookshelf unit I was building in a client's house. The jig worked great. I did crack the plastic by pushing too hard when drilling. When you attach the black guide to the clear plastic jig, the screws used to attach it do not sit flush/countersunk, but rather stick out a bit which added to the pressure being put on the plexi jig instead the being pushed onto the bookshelf.Also had a moment of user error. I was drilling using a 10.8 v driver that had the clutch engaged as I was installing face plates on electrical outlets & switches. I forgot to change the clutch setting back to drill, so consequently the drill bit would stop before reaching full depth. I didn't notice the clutch at first so was trying to adjust the depth of the bit by adjusting the set screw which lead to it coming apart into pieces, the spring shooting off, etc. This is in no way the bits fault, but can be chalked up to user error.

I'd always thought that a shelf-pin jig was a bit of a luxury item, as I don't really build many things with movable shelves, however it came in REALLY handy when I wanted to put a shelf extra low in an Ikea bookshelf.Really easy to figure out and use, and accurate. I can see myself using this a lot more.

Excellent!
