It does not appear on examination of the cylinder whether the jacket was cut out in order to reach the broken dome, or whether it was broken out originally by the damage. However, in attempting to put it back, the cracks kept on extending until the cylinder was cracked through two port plug holes. In addition to this, the corner of the cylinder as welded was much natter than it should be, the result being that it would have been impossible to grind out the cylinder without going through the weld.
