If you cut with a cut off wheel and make your cut at a 45 degree angle ( or thereabouts), it will make that gap a lot smaller. My problem with tracing is if you deviate from your line at all you’ll have a big gap or tight spot there.At one point I did it that way, however I now position the patch panel and then trace the outline where it will be welded. Then I remove the patch and cut inside of that line. This gives a much better fit and eliminates the gap for the most part.
