Let's take this one piece at a time.

The wooden ramp at the base of the Grand Gallery was necessary for your initial conjecture (that the blocks were stored on the floor of the grand gallery), which you then go on to debunk because they wouldn't have fit on the floor of the grand gallery.

The ramp was where they were stored.

From this photo (courtesy Jon B.), one can see where the ramp's southern end rested on top of a lowered area of the floor of the Grand Gallery, thus giving it extra length and support.

This picture shows the "direct shot" the blocks would have, sliding down their wooden ramp.

We already discussed, over a year ago, how the block could be inched down the passage, from behind, by alternating wedges into the opposite side in the back from the one that was binding in the front. You agreed you had not thought of this and were convinced it was a practical solution to the matter. No new evidence has been produced since then, ergo nothing has changed. It is still a practical solution to the challenge.

Now, about your tolerances...

Here's what Petrie has to say about it:

Quote

The granite plugs are kept back from slipping down by the narrowing of the lower end of the passage, to which contraction they fit. Thus at the lower, or N. end, the plug is but 38.2 wide in place of 41.6 at the upper end

Clearly the plugs fit into an area 41.6 inches wide, and it took a 38.2 inch wide space to get them to stop.

You're now somehow saying that a space of 3 inches is insufficient?

I think I see where you've gone astray. You make this claim in your first post:

Quote

These granite blocks total just under 15 feet in length (there is a 4” gap between two of them).

The upper end of the uppermost block measures 41.6” in width and 47.3” in perpendicular height.

The lower end of the lowermost block measures 38.2” in width (and therefore tapers in 1.7” from each side) and 47.3” in perpendicular height.

I think you are misreading Petrie's measurements... and I don't think he wrote them well, either, so I don't blame you. The stones aren't 41.6 inches wide... the passage is 41.6 inches wide at the place where the plug stones end. Read it again from my quote above and you'll see how he changes what he's supposedly measuring in mid-sentence.

Here's a picture of that "upper end", by the way. It's frankly amazing that anybody thinks they could get an accurate reading of it under nearly any circumstances, after Mamun hacked the stuffing out of it to get past it.

So, the blocks fit into the Grand Gallery for storage, and they easily fit into the shaft with over 3 inches to spare on the side. (38.2 inches at the bottom, versus 41.6 at the top). The top never narrows (as it did in the Trial Passages outside - A correction they made???), so that's not a concern.

I fail to see any difficulty here, except in the interpretation of Petrie's grammar... unless, of course, you have a corroborating measurement from another source? M&R, perhaps?
