Some more rust repairs.

 Before cutting the "car" I want to have "healthy" metal where the cut is made. Right side quarter panel is in bad shape. Tape shows where the cut is planned.

Shaping of this piece is mainly done by hand.
   

To check the shape I'm comparing repair piece to my car. Reshaping and comparing until I'm happy with the result.

Masking tape on backside of repair piece to not scratch the paint. 

Welding preparations.

I use a technique where I tack weld the repair piece on top of the damaged piece, this is just to hold it in place for now.   

Then I cut along the top side of the repair piece and and push in so that the repair piece and car sheet metal are flush and tack weld in place. 

When one have cut around all sides of the repair piece the replaced piece should hopefully be possible to take out as demonstrated in the video. 

After some more welding and grinding this is how it looks. There are still some holes in the welding joint that will require some more welding and grinding.

Frame for the sofa.

Although not all rust repairs are done yet I decided to get started on the frame for the sofa.

I bought some 30X50X2 mm pipe for making the frame.

Frame for couch bottom ready!

Manufacturing of backrest frame.

 Mocked up. Not happy with how it looks! Reluctant to weld in place. 

After some thinking back and forth how to proceed I decided to use backrest and weld it in place. Preparations.

Welded an angle bar behind the backrest frame for making it easer to install the backrest. Uncertain if this will be left on the ready product, basically it should be enough to just leave the parts connecting backrest to car. 

This is a milestone and next one is approaching fast! Soon time to cut the "car" to its correct length. 

Spin off project, bending brake modifications.

The sheet metal bender or bending brake that was acquired earlier in the project would have been better left in the store... Now that it is in the garage I might as well try to make some improvements to it.

So far I have been using 1 mm cold rolled sheet metal. 1 mm sounds thin but is actually a hard material that requires quite sturdy tools for shaping. Specification for the bender says max 1 mm but it is not optimal or even suitable for 1 mm sheet metal. The clamping bar and its fastening is the biggest issue. One is supposed to use loose clamps for fixing the clamping bar and the bar has a tendency to not stay in place when starting to bend the metal.

This is what the bender looked like before modifications. (I need to clean that table...!)

Preparing to weld stiffener to clamping bar.

I spot welded the stiffener bar in place going about it symmetrically and using compressed air to cool the spot weld after every spot. This to avoid heat distortion of the piece.

 

Preparing to weld stiffener to the bender. Removing paint where welding will occur.

Stiffener made out of flat bar welded in place.

Holes where drilled for fixing the clamping bar. The hole in the clamping bar is 3 mm bigger than the bolt witch gives some room for adjustment before tightening the bar in place. The use of drilled true bolts will limit the width of the piece worked on a bit but the alternative solutions would have been much more complicated and  time consuming to build. I spent enough time on this shi..eet metal bender as is.

 

Nuts welded to the bender for limiting the amount of needed tools when tightening the clamping bar. Common hardware store M10 bolts and nuts of 8.8 hardness are used.

Black paint applied to make it look ready.

The plan was to be done after applying paint.

But then I released it should not take long to make a "lift" for the clamping bar.

 

Reinstalled on the work bench. I haven't tried the bender since the modifications (and I haven't cleaned the table yet).

Rust repairs.

I cut away the piece of trunk floor that connects the trunk floor to the quarter panel.  The plan is to try and rebuild this part to look close to factory made. Measures can be taken from the left side witch is in better shape and re fabricate right side part to resemble.

In order to "mirror" the part from the left side of the car a template out of paper was made.

Something like that.

I wanted to try and make stiffening beads to the  repair piece! Not that they are needed but would look nice. Should have made the beads before bending the plate!

Made a groove in a piece of plywood and tried to form the sheet metal by hammering and using the plywood as mold.

The result was terrible!

In an attempt to rescue the situation I called a friend with a bead roller and went over to him and made the beads now the problem was that I had bent the repair piece witch limited the movement when using the bead roller. 

Well now I have beads not exactly as on the original piece but they will have to do!

Hammered the "lip" that connects to the quarter panel on free hand towards a piece of wood! As the edge of the metal is not in a straight line it causes the piece to get bent.

I don't have tools for shrinking and stretching sheet metal so the "lip" was cut to enable bending as needed.

Mocked up. It Looks OK!

Before welding in place the surface that will be facing outwards towards the quarter panel was painted with rattle can spray for rust protection as it might be hard to access later on.

Tack welded in place.

I wanted to try and make a "real" repair piece although this part will not be visible on the couch. The piece came out far from perfect but I'm still quite happy with the result.
