closing the firewall

First off i want to apologize for the hideous welds!
I find it super tricky to weld thin sheet metal with a stick!
I should really really really practice more…

anyway, there is some progress to report.
I’ve started with closing up the big gaping hole in the firewall of project hategenerator.
Aided with cardbord samples, then transfer that to thin steel.. and somewhat voila… it somehow sits in place.
