Finally got my brick corbel right on the third try

Last week I was working on a chimney rebuild in Springfield and the plans called for a 6-inch corbel. My first two tries looked okay from the ground, but up close the line was wavy. I went back to my old teacher's advice about marking every course with a story pole. Spent an extra hour setting up, but the third course went in perfect and straight. It's a small thing, but it felt good to nail it. Anyone else have a trick for keeping corbels true on taller work?

Wait, a 6-inch corbel? That's a big jump per course. Most codes limit you to a third of the brick depth. A full 6 inches out would be over 2 inches per course on standard brick, which is asking for trouble. You sure the plan didn't mean a 6-inch total projection over several courses? For tall work, I mark the full profile on the wall with chalk first. Story pole is good, but you need the full angle laid out.

Yeah, it's like when people skip steps in a recipe and wonder why it fell apart.

So what's the actual total projection then?
