Rust repairs, getting started!

My earlier experience of sheet metal work is very limited! To get started I have purchased 2 square meters 1.0 mm cold rolled sheet metal. This should be fairly easy to shape I've been told.

I bought a used MIG welder for my iceboat project that will be used here also. 

I could't help the temptation to purchase a small sheet metal bending tool.This one is small and can only (barely) handle max 1 mm sheet. Also the width is limited to 760 mm.

Manufacturing of repair pieces.

The "leaf spring fastening point".

The welding was started where the smallest repair was needed, left sub frame. Hoping to gain some experience before the more demanding repairs.  

The welds looks like crap but it will not be visible on the ready couch! Hopefully the welding quality will improve before the quarter panel needs to be welded.

As the right side sub frame was in worse shape I welded a temporary stiffener before cutting away the damaged part.

New piece of "sub frame" in place.

I rebuilt something that would look like the rear leaf spring fastening point even if it is basically not needed now. I'm thinking it might come in handy when installing feet or wheels or combination of the two under the sofa. Also it looks better when both sides are alike.

Next on the agenda is to try and bring the right corner back to life.Starting with re manufacturing the piece below.
