2 granite carving sequences

George!

Thank you yet again for stepping up to the plate to swing
at my "granite ball" pitch.  I wonder if that tool in your
old T and H catalog isn't a hand facer.  I've talked to
them about that tool and they say it predates the carbide
era and won't say if it will retain the carbide tip any
better than my 9 pound rock drill is doing.  On that tool
I am using 3/4 in carbide bush tip they make for their
11/16 shank hand facer.  They solder it onto a 7/8 shank
which my rock drill uses.  Soon as I turn the air up to
where it's really moving stone, the carbide tip leaves the
shank.  It takes alot of self control and an air pressure
gauge.  I haven't yet determined the maximun air pressure
allowable but I think its around 60 pounds.

As far as other hammers you must be thinking of chipping
hammers.  As with the rock drill, I don't believe anyone
in the US makes a carbide tip bush tool for air tools.  I
just spoke with Ajax, one of the leading manufacturers of
hammer chisel and bits.  All the demolition carbide tip
bush tools are for electric hammers, SDS and spline drive.
 Perhaps I could wangle to use one of those in my rock
drill or a chipping  hammer which I don't have.

Any guess what those tool marks on page 2 of the second
secquence are from?

Are the drill holes?  Has he drilled so close to the
surface of his face?  I'm thinking he has.

In the first sequence of the abstract piece.  They show
what looks to be flush mount sawing with a large blade.
It looks as though it is done after the driilling breaking
and point work and before the bushing.  I was surprised to
see sawing done like that along with the plane of the
surface.  They also so sawing with the 4 inch blade
perpidicular to the surface in the hollows along a ridge.
That I expected.  I wonder it they broke those ridges by
hand or went in with the bush chisel.
(An easier way to do it
may be to count to the ninth
set of question marks below
the set of question marks that
consists of two large question
marks, a space, one large
question mark, a left hand
parenthesis and five small
question marks and click.
Now click the purple question
marks here and the sequence
will begin.)

Any way thanks George!
