![]() This will give me a very slight oblong hole in one axis only and provide me a little wiggle room for final assembly to keep the front (edge banded edges) perfectly flush while still maintaining tight hole in the other axis. 010" of play so I can plunge once then slide over the. I think the best/easiest thing is to build my fixture with an extra. In the end nothing is perfect everything has some type of tolerance/error including the material and dowel itself. Being able to dial in the amount of slop you need or want would be really nice. If festool ever updates the Domino a infinite slop dial would be awesome instead of just having 3 settings. This is the big benefit of the domino over the Dowler but the domino also puts in a little to much slop for me. Turns out after further investigation part of the issue was the ddf40 fence is not Perfect either. I was actually more than happy with the overall accuracy of the cnc before getting into this but I was recently working on making some vacuum fixtures for the DDF40 to end bore holes for dowels to match the cnc face bored dowels and had an issue that one side was off. So, this got me wondering if the steps per inch was wrong or was my tape off and prompted the class 1 tape purchase. 040" out over 95" using the steps per inch from the R&P specs. This all started because when I checked with this method using my stanley tape I was. Much more than that and I really need to start questioning my OCD. At what point do you draw the line building furniture and cabinetry? The class 1 tape isnt only for the cnc but to quickly check/verify other tapes and rules with "reasonable" certainty. ![]() ![]() At some point the accuracy is just overkill. Not to mention wood movement, temperature, humidity etc. Most R&P machines wont come close to that tolerance anyway. 030 depending on my eye then divided by 96" of travel is. The class 1 tape specs out to +-.3mm at 2 meters. The biggest variable at that point is the tape not my eye. I can really pin point that v bit to the center on the line on the tape very accurately. But its all good, The tape measure and a very fine v bit (the one im using is 3mm bit and 20° the things needle sharp and never used for cutting) actually works surprisingly well believe it or not. There is no need to convert the fractions as you must do when using English units or Imperial units.No I dont. To read a metric ruler you simply count the sections. Metric rulers use marks called centimeters which are divided into 10 sections called millimeters. While The Ruler Game only teaches you how to read the standard English Ruler, or Imperial ruler, there are also Metric rulers. Measurement is just one reason to learn fractions. As you can tell, reading a ruler is a valuable skill that you will use almost every day both on and off the job. Computer programs like Microsoft Word and Adobe PhotoShop have electronic rulers that you can turn on to help you with the exact placement of items. For more information, see How Do I Read a Ruler? at .Ĭheck out TechEdLearning's excellent video tutorials on how to read a ruler!Īlthough you are probably familiar with rulers, yard sticks, tape rules, folding rules, and tape measures, you will also find rulers on many machines that you use such as saws, sewing machines, photocopiers, and computer scanners. If you use The Ruler Game to learn to read down to sixteenths, you will have no problem reading thirty-seconds and sixty-fourths if you ever need to. You can use the optional "Increment Leve" to learn the larger marks before graduating to the smaller marks. Some rulers will even show you thirty-seconds and sixty-fourths. And each of those eighths are divided in half to give you sixteenths. Each of those quarters is divided in half to give you eighths. Each of those halves is divided in half to give you quarters. The standard English ruler, or Imperial ruler, is divided into inches. ![]() Without measuring devices like rulers (and people who can read them) we would still be living in caves. Reading a ruler is a valuable skill that you will likely use on your job, in your hobbies, and in your personal every day life. You should really Check it OUT > Why Learn to Read a Ruler?
