2 granite carving sequences

[abknight@zzzzzz]

Hi everyone, hope everyone is well.

George, in particular I have more questions about the
granite carving sequences if you do have the time.
It regards the first carving sequence of the bell like
shape where you have to go to the set of question marks
with the five lower case question marks that are following
three or so upper case ones, then count down to the ninth
set of question marks below and click!  I don't know if
anybody did that, but there is much of interest to the
beginning granite carver there.

In particular I would like to know what the blue four inch
grinding disc might be that the artist is using to smooth
out the bush chisel marks of his helper.  George what do
you use for that purpose?  And George is that a T and H
hand facer the young worker is using?   Thirdly in the
picture where there are three at work what is the guy in
the middle doing while the guy in the back bush hammers
and the artist to his right grinds?  I get the impression
they did this work on location, away from home and they
knocked it rather quickly.  Any guesses on a time frame?
