While waiting for the 3d print of the seatcowl I started work on the frame of the chair. The original chair has a bent/welded metal tube frame. I dedided to make the frame in 4mm messing tubing (1/4 of 16mm original) wich is easy to bend and solder. A cleaner technique then spotwelding metal rods and thus -hopefully- less work with cleanup afterwards..
In the tubes I put some fitting coper wire to prevent the tubes from deforming while bending. Making a male and female ‘connection’ between the different parts of the frame made it easy to fit the together and solder.
