Tape Measure Comparison Stanley Komelon Quickdraw Trust Stanley Powerlock Pink Box eTape Ubante Magnelex Lufkin Size (Inches) x x   Having a good quality tape measure may not be in the forefront of most people’s minds until they need one. It is a good idea to have at least one tape measure in your tool box but since they can easily disappear, you might be better off having several around your home or workshop. There are many types of tape measures on the market, from simple, fabric styles to high-tech digital models. They are used for tasks that require measurement and are critical tools when it comes to ensuring correct project measurements. With a digital tape measure, you can measure lengths on a great distance, and they can calculate area, volume, and much more.

I used these guages which we called air probes, way back in They were perfect because they would show exactly where your out of roundness was located. We were able to show deviations in the tenths.

We would mark the area and allow the electroplating shop onsite to build up the area out of spec. Saved many expensive parts for further machining processes. Three-point Bore Micrometers tri-mics, as we called them will not show out-of-round conditions very well, because they show an average for the location being measured.

Dial bore gauges give the best picture of what the bore actually looks like at each location being checked short of a CMM.

Air gages ar fine but must have a Super good r. Self centering Self aligning. Tri-mikes require calibrated ring gages to check the low, center, and high ends of the measuring range. They also have a cone that is prone to wear when used in one area. Close tolerance work also requires a temperature controlled environment of 68 degrees F.

The problem og getting an accurate measurement can lie with the hole at least as much as the gauge. If the hole is well finished and round and not irregular the problem itself is easier thna otherwise.

There is another type of gauge with two almost circular measuring elements forced apart by a tapered wedge, that is also accurate, but it sits on the peaks of any surface imperfections more than the 2 point opposed buttons type in the article, so a practical hole, with a less than perfect finish, can look to be a different size depending on which of these measuring approaches is used.

A part of my working life is to measure the bores to fit bushes that I make to accomodate things like the camshafts in classic motorcycles and I usuually end up using more than one method and going for the one that seemed most reproducable when I was doing the measuring. There is anothe method I use a lot, and that is the tapered hole measuring wedges that Starrett used? These are very reliable, they can be padded out with parallels to increase their range, and when you use a micrometer to see how far apart the measuring faces are, you quickly get a feeling of confidence.

I have done measuring with these to 2 tenths and they delivered OK. Just my views. Dentists are also into boring — whether it is entertaining depends on whether you are the boreR or the boreE….. I cannot agree that telescopic gauges are not accurate. To use a telescopic gauge lock the gauge in the bore at an angle to the bore then full the handle to be parallel to the bore.

The faces of the gauge will move to the precise diameter. Then use a bench mounted micrometer Telescopic gauges will measure accuracy to microns provide you have a good surface finish The telescopic gauges do eventually wear out. After 60 years in the trade I have a number of worn out gauges These gauges are especially convenient when boring on the lathe , mill or line borer.

Digital calipers are easy to use and require very few steps to get started. However, not taking the right steps can lead to inaccurate measurements. The most important step is to ensure that you start from zero every time. The best digital calipers reset to zero as soon as they are turned on, if this is not the case with your, then press the zero button and you are ready to go. Positioning is the next most important step. The position of the jaws is different for each type of measurement you need to undertake.

Measuring outside dimensions — to accurately measure the outside dimensions of an object you need to position the inside of the jaws parallel to the object. This gives you the most accurate reading. If you want to measure thickness, then the inside jaws need to be perpendicular to the object. Measuring inside dimensions — to accurately measure the inside dimensions of an object to need to position the outside of the jaws perpendicular to the object.

Measuring depth — to measure depth, you need to engage the depth gauge and position the caliper perpendicular to the surface that is being measured. Measuring step — You need to use the step gauge to measure the distance from one edge to the edge above it.

Comparative measurements — to compare one set of dimensions to another, you zero the calipers while they are in place. Digital calipers are precision measuring tools. If they are not looked after properly, then they will take inaccurate measurements and could cause major issues with any project you are undertaking.

Proper care includes ensuring that the caliper is turned off and stored correctly at the end of every use. If it comes with a custom-made case, then ensure this is used. Other steps that you can take to ensure that your digital caliper maintains its accuracy include:. A: A digital caliper is a precision tool that is used to take very accurate measurements.

It is more accurate than a dial caliper and includes a digital LCD screen, so it is easier to read the measurements. The caliper can be used to take internal and external measurements on an object.

It can also take depth readings and step or comparative readings on different parts of the same object. The caliper is calibrated when it is manufactured to ensure the most accurate reading possible. However, because it is an electronic, calibrated tool, it requires additional care. Failing to care and maintain it properly can affect the calibration, resulting in inaccurate readings.

A: Digital calipers work using a series of capacitance sensors. These sensors run the length of the beam. As the distance between the jaws is changed a change in the electrical charge is triggered.

This change is detected by the sensors. All of this is possible because of a number of engraved rectangular plated placed on a glass or copper strip. A circuit board is present on the underside of the movable jaw. This along with the engraved plates forms the grid of capacitors. The rectangular plates align and misalign as the sliding jaw travels along on the main scale; this changes the amount of electrical charge between the plates.

The signals are sent to a chip in the caliper, this, in turn, creates the readings that are then shown on the LCD display. The caliper contains a Vernier scale alongside the main scale and is made from high-quality stainless steel. The caliper has a measuring range of 0 — 6 inches and includes an extra-large LCD display.

The best digital caliper should have at least the following features: Depth gauge — this allows you to measure the thickness of an object as well as hole depth. Locking screw — As its name suggests, this locks the caliper jaws in place so that they do not move or slip during measuring. Step gauge — this allows you to measure from the edge to the point of an object. ABS button — allows to you set your measurement to zero temporarily.

Outside jaws — for measuring the inside dimensions of an object. Inside jaws — for measuring the outside dimensions of an object. Care is needed with these jaws as they are often delicate, making them prone to breaking.

Zero button — this sets your current position to zero and is often also the power on button. The very best calipers also convert measurements to fractions. Automatic off — this save battery power by turning the unit off if it is left idle for a period of time.

Most switch off after five minutes of inactivity. Stainless steel construction — makes the caliper sturdier and offers a smoother finish for a smoother movement, making them more accurate than calipers made from other materials.
