Scenario: You make it out to the woodshop after a hard night of drinking. = As the acetaldehyde takes it's effect on you, you drop your Starrett square= on the concrete floor. What do you do? Continue to use it and hope for t= he best or check to see if it's still of 'Starrett Quality'? How do you ch= eck?
My sentiments exactly.
I'm by no means a teetotaler, but I haven't had a "hard night of drinking" in over 20 years. And if or when I did, I sure wouldn't head to the wood shop afterwards. And if I did, I probably wouldn't use one of my Starret squares. And if I did use the Starret, probaly wouldn't drop it. And if I did happen to drop it, after a hard night of drinking, I probably wouldn't care enough to check it.
What was the question again?
Then why did you buy a Starret? :)
Yes, there was just probably some confusion aboutnotation. I just don't think his present work is "camera-ready" yet, for publication. I think the work needsmorediagrams.
Thanks, Bill

Not at all. The red d2 is above the red line. d denotes distance.
The passage "take a reading at the bottom of the square (d2 in Figure 1)" should have clued you in that d was a distance. We are, after all, discussing a dial indicator method. Dial indicators measure distances.
" Tilt your miter gauge to approximately 5 degrees." You can't tell that the miter gauge and square are tilted in Figure 1?
Point out what you think needs a do over. If you have other questions let me know.

Yes, usually. It is however, not incorrect how I used the term.

That'll work. Feeler gauges will probably work better.
answer that question so why bother checking in the first place?
Of course you can easily answer that question. Decide what percentage error is acceptable in your project, and you can easily calculate the permissible gap between the marks. Suppose you want accuracy to one part in 1000 (99.9%). The gap between the pencil lines at a distance of 8" -- double the error in the square, remember -- must be no more than 8 * 2/1000 = 0.016", which is easily measurable with feeler gauges, a dial caliper, or a mike.

When you submit your work for publication, the publisher will advise you in no uncertain terms how it it should appear. While your idea may be just fine, having reviewed a few books and papers before, it is my humble opinion your your paper needs work. I would look forward to seeing your ideas presented again. As has been suggested, this isn't rocket science, but the application of using the magnetic cubes to check for accuracy in squares is an interesting application. Why settle for good-enough.

I guess that we never had a "meeting of the minds" as to what your procedure was. More descriptive writing would probably help.
Sorry for any mix-up I may have contributed!

A distance of 0.016" equates to an angle error of 0.5 degrees for your 8" square. Would you calibrate anything with that "Square"? I wouldn't.
What is your limit of detection for measuring gaps between lines? I hope it's less than 0.016", but I can understand if it's not.
You mean between two points--or two parallel lines. I agree that feeler guages seem suitable.

Doesn't happen in my shop. That's a hard and fast safety rule here: if I drink, I stay out of the shop until after a full night's sleep.
That doesn't mean I can't or won't ever drop the square, of course -- just means that if I do, it will be the result of my own innate clumsiness, not of inebriation.

Your imagination is lacking, Brian . I can think of at least half a dozen things I could check it against:
-- angle between the jointer fence and bed (previously set using the same Starrett square)
-- angle between the fence of the Incra 3000 miter gauge, and the miter bar (ditto)
-- angle between the Incra 3000 and the table saw blade (ditto)

I've read more than my fair share of peer reviewed scientific publications. And as a scientist, I've written a few peer reviewed as well. I have never heard of a reviewer who had a problem with using 'References' in the fashion that I did.

Good. The math is sound. Let's see something from Bill to the contrary.
