From Close to Perfect, In Just One Tool !
By Bob Feeser
Commonly we use a tape measure to mark our work piece before cutting. The small tab at the end of our tape measure is always loose. Some argue that it was built intentionally that way, so that when you stretch it, it slides to make up for the allowance of the thickness of the tab. When compressed, it slightly shortens the length to once again make up for the tab. That sounds good, until you actually measure something with it both ways, and come up with a 32nd of an inch or more difference. If we are rough framing that is fine. When we are doing anything that doesn't demand close tolerances, it suffices.
What is interesting, is that the smaller the cut, or the finer the project, critical tolerances become all the more important. Installing a set of kitchen cabinets, and you have to nick a 1" corner in something. That can be difficult to do perfectly. If cut wrong, it stands out like a sore thumb. What this Precision Marking Rule will do is give you perfect lines effortlessly. Less time spent, and undeniably exact markings.
Incra designed this so that each measurement, whether you are measuring to a 32nd or a 64th can be done almost without your glasses on. Each measurement is marked with a small hole next to it. In there fits the tip of a .5mm mechanical pencil, or sharpen a regular pencil to a fine tip, give it a couple of twists to center it in the hole and you are ready to go. What I did in the past was use a framing square, park my pencil on my measurement, then try to hold it still on the square, while I glided it along. It normally wouldn't hold totally true. With this rule, it prevents the pencil-marker from floating. It stays in the hole for a flawless measurement along the entire line. It is not harder, it is easier.
You can see how ultra fine this capacity is. As a matter of fact the incra system is the most exacting measuring, fencing, and marking systems available. Some things we don't need this level of accuracy. On the other hand, once you get into the "incra"mental system, their is no going back. It takes less time, for better results. I just bought the Incra TSIII-32 table saw fence system, and I am sold on the timesavings, and ease of use in doing it right, instead of getting it close.
It is nice to know that if I am dealing with tight tolerances, this is standing by to give me the flawless measuring I need. Even if I am scribing a line along a board, that I need to run through the jointer, I know it will be exact. If I had to be critical on the piece, I would say that since it is for fine measuring, the T-slot aluminum track is substantial, but the metal on the measuring face is thin enough that you wouldn't want to step on it. A thick framers square could be dropped off of a second story, but it won't give you this kind of exactness. For the money, you can't beat this rule. Highly recommended, buy it you won't be sorry.

Absolutely Repeatable Marking. Best Tool Ever for Mortises!
By Jeffrey A. Smith
I echo the words of the other reviewer. I use this thing all the time. It is the only measuring device I ever use when laying out mortises.
Try this with your ruler. Mark 3-31/32" from then edge of your wood and then lift your ruler, move your wood around and try to use the same ruler to make the same measurement. I'm not saying it can't be done, but with this thing, you can draw a .5mm line E-X-A-C-T-L-Y over the one you previously drew. It's not off by a "hair" or a "smidgin" or "a little", it's dead-on.
By sliding the "fence" on this t-rule across your edge as you make your mark, it's possible to make a repeatable and exact measurement from the edge of your board all the way down the length of the board in any increment (down to 64ths).
I stress repeatability because that's very important when trying to mark two separate pieces exactly the same.
Since this ruler came into my shop, I occasionally amaze myself, and that alone makes it worth the price!

Do you cut a lot of tenons and mortises?
By B. Bachman
Here is my summary for this tool. "Wow". That's it.
Do you cut a tenon now and again? Buy this. Do you cut a LOT of tenons like me? You HAVE to get this T-rule. With a 0.5 mm mechanical pencil and this tool- well it takes me less than 30 seconds to lay out a tenon- and the mortises are even easier. And the marks are perfect. It took about 4 tries to get the sliding down a board while marking- but now it seems like the easiest, fast, and most natural way to mark anything. I'm not a production shop- this is my "spare" time hobby. And the amount of time saved and accuracy I've gotten from this meager investment... I would honestly say having used it now for a few months I would pay 4 times the price. Okay, that does sound corny. But I'm serious. I have the Powermatic 719A Mortiser, a cabinet saw, Forrest Woodworker II, and this T-rule... and I swear the hardest thing I do now is sanding before the finish goes on. Buy the 06. The 12 and 18 are just too big to use on most furniture parts.
