It is obvious from the comments being made that there has been no real "in-depth" examination of the study of the Great Pyramid, but only a few remarks given to mislead and influence others away from any actual "in-depth" study of God's Stone Witness in Egypt.
In ancient times the easiest way to measure things was to use the most convenient measuring tools available that anybody could afford to own: your OWN BODY PARTS!
Yes, Yahweh, of course, has no use for measuring things with body parts. Yahweh knew that diameter of the earth between its two poles. Although there is a general assumption that a cubit was originally the length of a person's forearm, there is no indication that Noah was told to use any part of his body for measurment.
1.Had a unit of measurement accurate within one-ten millionth of an inch.
Whether the ancient Egyptians knew of this measure or not is irrelevant, as God knew measurement of the earth. Evidently, the measurement was known amongst the Hebrews, and the Egyptians, having been descendants of Noah, would probably also know of the measurement. It would not be necessary, however, for either the Hebrews or the Egyptians to know the significance behind the measurment.
2.Had knowledge of the earth's radius
Again, no, the ancient builders did not need know of the earth's radius. God, of course, knows the earth's radius, and its diameter.
3.Had the physical means to trim sandstone with one ten-millionth of that inch.
Again, whatever "abilities" that were needed by the builders could certainly be supplied by the Creator of the earth.
4.Erected a stone edifice whose SOLE INTENTION was to inform Charles Taze Russell that his Divine Plan of the Ages had the correct time alignment with history!!!
This conclusion is obviously inaccurate, and is stated simply to leave one with a false impression, since the Great Pyramid displays much, much, much, much, much, much, much, much, more than just a corroboration of the chronology that Russell adopted from Barbour, who, in turn, had adopted the chronology of Christopher Bowen. Russell himself, however focused on corroboration of the chronology by the measurements of the Great Pyramid. John and Morton Edgar presented a tremendous amount of other information.

607 B.C.E. has as much scientific actuality as the Pyramid Inch of Charles Taze Russell.
I believe the the phrase "pryamid inch" is misleading; I believe "earth inch" would be more correct. Many refer to this inch as the "sacred inch". Nevertheless, this "inch" did not originate with Charles Taze Russell. The discovery in recent times of this inch is usually attributed to Sir Isaac Newton, long before Russell was ever born. Nevertheless, Newton himself showed that this form of measurement was known long before himself.

Charles Taze Russell was forced out of necessity to use charts (Divine Plan of the Ages) and Great Pyramid speculations to PROVE his theology.
No, I have absolutely no reason at all to think that Charles Taze Russell (or Barbour) was forced out of necessity to use charts (Divine Plan of the Ages) and the Great Pyramid to PROVE his theology. This is totally ridiculous! Russell did use the Chart of the Ages as a means to illustrate the various features of the God's Divine Plan as presented in the Bible. Was he forced out of necessity to do so? Absolutely NOT! The Chart of the Ages is simply an aid to help to the reader see an application of the scriptures to the various time elements of God's purposes.
It was evidently Barbour, or someone associated with Barbour, who first presented the measurements of the Great Pyramid as corroboration of the Biblical chronology. Was Barbour forced out of necessity to use them? Absolutely NOT! He already had an abundance of evidence from the Bible itself.
Russell adopted Barbour's conclusions in the year 1876; over the years Russell rejected some of Barbour's conclusions, but not the overall chronology. The GP, however, is only a very, very, very, very small amount of the evidence supporting the chronology.
What most people don't know is that after he got the approval, Russell CHANGED his computations and printed the Thumb's Up AS THOUGH the new figures had been reviewed.

I have no reason to think that the text sent to Smyth did not contain the same text as appeared in the Studies. I could not find any verification that the text sent to Smythe was different from the text that appeared in the Studies.
I assume that this is concerning the measurement given by Russell of the floor of the descending passageway, since all of the other measurments are the same as that of Smyth. As far as I know, Smyth had the text in which Russell wrote concerning the descending passageway, and that text was what originally appeared in the THY KINGDOM COME.
The problem concerning the decending passageway was that Smyth did not take a measurement of the floor, but of the ceiling. A floor measurement could not be taken since the passageway was filled with debris. Probably Barbour or Russell, or someone else associated with them, tried to use Smyth's ceiling measurements and project those measurements down to the floor. It was not until 1909 that the debris was removed and an actual measurement of the floor was taken.
It was not until 1905 that Russell changed his understanding of the measurement as given for the descending passageway. Of course, Smyth had died a few years earlier, and he could not be consulted concerning that change. It appears that Russell, or someone associated with Russell, had come up with evidence of a different measurement for the floor of the descending passageway. Russell sought to the correct this in the 1905 edition of THY KINGDOM COME; he failed to note, however, that the letter from Smyth would not apply to the new calculation, and such a thought probably never crossed his mind.
Indeed, in 1904 Russell changed his viewpoint concerning the beginning of the time of trouble. He had before 1904 thought that the time of trouble was to end, not begin, in 1914, which thought he had adopted from Barbour. In 1904, he adopted the view held by some of his associates that the time of trouble was to begin, not end in 1914. Although a few changes were made to reflect that 1904 change of view in the Scripture Studies, no exhaustive overhaul of the Studies was ever attempted, so that, unless one is aware of the history, some statements in the Studies as he left in them in 1916 may seem to be confusing to some.
Many have made much ado over this, and evidently either being ignorant of the situation, or deliberately desiring to mislead others, have misepresented this matter, leaving the implication that Russell was willfully misleading others.
