Norman,
Great questions, as usual!
When I've needed to make a block with a rock pitched face that is 18" tall
for example, I start with a quarry block with a good clean split face, and
then pitch the ends and corners. You have to plan ahead and save the split
face surfaces, or get a block that you can drill and split in half so you
have 2 split face blocks that are usable. Pitching slabs over 12" thick is
very difficult with hand tools, and the waste of stone when using a bull set
makes is very expensive, when you are working with expensive slabs of
granite. At this thickness , drilling and splitting is way more efficient.
When you have a ridge of stone in the middle that did not get pitched off,
you have to get creative. A point or splitter can sometimes knock the high
stuff off, or cutting a ledge do the tools can get a good bite is needed. Of
course any time you hit the stone you leave a mark.
Pitching off an angled , beveled or rounded surface is very difficult, and
sometimes impossible. You just have to try, or do the pitching first, and
then the carving.
George Graham, PS, I haven't been using the spell checker recently, as some
may have noticed, sorry!

Norman asked,

Quoted text begins.How do you pitch when the stone is too large or improperly shaped to be
positioned so that you can pitch downward? Is it at all practicable to
pitch non-horizontal lines?
