Re: THe NAC Lots-O-Post Thread
What's fancy max load? I hear you want one with a dial on it. Looks like I have most of the tools I would need and the ones I don't I wouldn't mind buying. Know a good place to buy the micrometer and dial indicator(and accessories)? Also do you think a micrometer is really necessary or could a good pair of digital calipers get the job done? I will need this stuff for when I rebuild my TH400.
A max load torque wrench is a fancy beam style, where it has a dial on it, and has 2 needles. One needle moves and tells you the current torque that is being applied, where as the second need is a "max load indicator," and is moved by the other needle, and is moved as the first needle increases, but stays put to the highest torque that was applied, after the load has been removed. This is so that you can focus on turning something to get an accurate reading, and not try reading the gauge at the same time.
Now stay with me while I type the response to calipers vs. micrometers.
Alright, mircometers are more accurate than vernier calipers (digital vs analog doesn't matter, its just the method of reading the measurement that is different, they make the same measurements).
With vernier calipers, you can easily get a false reading by the amount of pressure you put on the tool. If you have ever measured something flexible, the reading you get can change greatly by how hard you squeeze it. Also, the reading changes the farther away the object you are measuring is from the body of the calipers. If you are measuring something at the very tips of of the instrument, then there is more leverage on the measuring arms, they can bend slightly, and the body can twist on the slide slightly.
With Mics, they actually have a mechanism built in that once it exceeds a certain torque, it skips gears, so that you can not over tighten the instrument and obtain a false reading. This will give you a more consistent reading, that is more accurate.
