I'm A Welder Now! Not Really, But Trying.

Dan, you'll have fun with that patching (you previously mentioned chinese water board torture?) It can obviuosly be very tedious............
Sometimes it is easier to cut the patch a bit larger and then trace out line over hole and cut carefully with a jig saw....then fit .....check....... grind ......fit..... check..... grind.....
get it perfect then try not to blow a hole in it and start over...

Keep at it..........you'll get it............practice makes perfect..........
Just my non expert 2 cents
