I like to use C.A.D for templates (Cardboard aided design) (IMG:style_emoticons/default/lol-2.gif)

Didn't use carboard as compound curve so it didn't work for me,cut the repair panel and bolted it on as mentioned and profiled to the hole,however the welder was way smarter than me (electronic ) and only got good welds near the end cause have little or no experience in welding panel steel.
Last build I did after buying this machine was building a heavy single axle farm trailer and used 5mm thick box section,so easy on verticals a great machine.
End result was a little messy but will clean up ,mostly enjoyed getting that "education" after years of welding heavy stuff.

All cleaned up with light skim of filler to tidy up after leveling off the welds with my new Dremel copy rotary tool which for the money has been a real asset .
Real pleased with end result for huge hrs spent which is not an issue as I have retired as of Oct this year.
Take my hat off to the guys doing rustorations ,the welding is quick but getting patch panels perfectly profiled and with least gap in is very challenging, I feel blessed as my car is not rusty.

Cheers.
