Just need some insight on an Allan Block corner. We are doing a wall with 6 degree AB block, which we've used in the past. The problem is this wall needs corners that are more than 90 degrees. The last wall we did with these stones only had 90's and I assume that they don't make another block for corners that are more than 90. I know that they changed to this new corner block but just wanted to confirm the cutting to achieve the new corner( more than 90). Any help would be apprecitated.
