    I never had any "maths" exams. MATHEMATICS was a very strong subject for me in high school and my minor in college. I rarely relied on rote memory when being examined. I preferred to understand the...

    Don't look now, but I believe you are arguing against yourself.

    Not so many years ago I had my first personally owned computer. At first it only used magnetic tape (cartridges). Then floppy...

    Store digital data forever? Probably impossible. On the other hand, one should never assume that anything that has been put on the web is completely lost. All those Hillary e-mails are still out...

    Curse you Red Barron. I will never get that version of "Pop Goes the Weasel" out of my mind.

    His simplified method took the internet equivalent of several A size paper pages.

    I can write the good, old fashioned quadratic equation solution on a single line.

    x = [-b +/- °√(b^2 - 4 ac)]...

    First I would make an accurate CAD drawing. Paint sucks for mechanical drawing. And there are enough inexpensive and free 2D CAD programs out there to give you a great selection. (I use FastCAD, but...

    How could I possibly make a suggestion when I don't know if this is a round hole in the end or a groove around the OD? And you say the flat is about 1" deep, but the sides are only 0.005" long? It...

    Woah Doggie!

    And I would bet that you will be the first one to rave about the virtues of form taps which also deform metal past it's elastic limit. Well past that limit. And a form tap will...

    Yea? Well I have met with idiots that can get past anything that you think is idiot proof. And they are a lot better with ordinary things.

    A lot here on why a company does not want to have a tech. on call. My answer to those reasons is that if it is a well designed product that is properly made, then there would be very few calls and...

    I noticed that only one reply mentioned a good tapping fluid. So I will second that. Do, DO, DO use a good tapping fluid. I also like Tapmagic, but there are others.

    You talk about a sharp tool vs. a dull one. But I suspect, well I know it is not that simple. A tool is sharpened to some degree. Some new tools are "razor sharp" while others come from the factory...

    Having used both digital and analog scopes for over 55 years I must disagree with the ease or use. Analog scopes, at least a decent one, are far easier to use and will provide displays that are far...

    The problem with any kind of circuit or meter that just averages out the pulses to give you a DC value to display is it will respond to noise just as readily as to the actual signal. I don't think...

    Wavelength and distance. Bingo!

    Noise canceling microphones have two pickup elements or entry ports, one facing the speaker and the other facing the opposite direction. These two are very close to...
