I am having trouble making the cuts for the cap stones on a 90 degree bend using cst block. I have a straight run that makes a sharp 90 degree bend at the end of the wall. I need the caps to line up on the front and back of the cap before it all the way around the bend evenly. I can't have any gaps. I wanted to end the wall with a square 90 degree, but the homeowner wants all curves. How do I make these cuts? I think the answer is to make a bunch of small keystone shaped pieces around the bend, but I would really like to avoid making a bunch of small cuts, since it won't "flow" with the rest of the walls.

Can you provide a drawing, are you using a die grinder?
Draw a Double Radius and reduced scale and draw what you want, Lot easier to correct with an eraser.
Good Luck

It would be nice if you foun a round disc of the material you want.
Cut into 4 pieces like a pie, 90 degrees, and use 1 at each corner?
