Now the pedal are painted, I'm going to waste everything if I try to weld the holes now

. But thank you for the advice.
But I I have an idea : you see the crimped collars ("ferules") of my brake lines? They have a 6mm inside diam and a 8mm outside diam, with a small flange, so I will cut 2 of them 10mm long, and use them as hat-spacers on each side of the pedal shaft
