Infact, looking back at my logic; a 15,000 kg block cannot be fully processed in one day, using copper tools, and even with a 15-20 man team. It would
take half the day to just cut out a rough rectangular shape, and at least another day to accurately shape and possibly a final day to polish it to
significant flatness and ensure all the dimensions are correct. I'd say a 15-20 man team, could AT BEST with the assumed tools, prepare a block
completely in about 3 days.
That just #s up all my maths, and even puts my extremely generous and unrealistic assumption at almost 200 years completion time, and my realistic
model at 1500 years. 2 days is the absolute minimum for a 15-20 man team to prepare a 15 tonne granite rock to significant flatness and shape, polish
it and ensure all dimensions - using copper tools. This is not including transport time.
This is annoying me, it is really tricky to get the maths to say anything realistic for the total time (< 50 years) without making ridiculous
assumptions for everything else. The only way it could have hit the 20 year range is with the use of machinery, as a block would have to be processed
within a few hours across all teams.
At my work, if I was to head down to the manufacturing bay with a 16 tonne piece of granite, and say to all the workers there:
"Lads, can you cut this down to a 15 tonne, rectangular block of X by Y by Z dimensions and with flat faces to a 1/1000th of an inch accuracy in
relation to eachother, polished to a surface roughness of Z, by the end of the day please"
I would get multiply bombarded from all angles with: "# off, mate". I know they can't do that without working their arses off for the whole day and
that's with the use of many great machines and cutters we have at our bay. At best, it would take them 5-6 hours in that exact scenario - being
realistic since humans are not 100% working machines and need breaks/time to think and things tend to go wrong at some stage etc. But if they had
everything plannen already and the correct system set-up to transport the block from machine to machine/work space, then we are talking 2-3 hours, and
to a good accuracy and finish.
By that comparison, there is NO WAY a copper tool wielding, 20 man team is completing a rock in one day. The more I think about it, the more I'm like
'not a chance'. I don't know whether to laugh or cry at the established 'one block every 150 seconds' figure lol.
