Unpopular opinion: a 2x4 kicking out at the top of my arch after 3 courses taught me more than any YouTube tutorial
I was rushing a garage arch last Tuesday and skipped the corner block tie-in, so when the lumber came out everything above it spread about 3/4 of an inch by the time I got to the spring line, and now I want to know if you guys mortar those back in place or just tear it down and start the course over.
