26. Use a black permanent marker for high-spot check. Cover the end surface being squared.


27. Place a 3/4" x 3" bolt (anvil blank) in and pressing the head against the end surface, give it a twist. Where the black is rubbed off is the high spot which is where material needs to be removed. Repeat until good contact all around.


28. Place the bolt in the 3/4" piece, and drive it into the 1¹/4" piece to 1¹/4" protrude from the end. Weld in place.
