Welding on a steering shaft gives me memories of Senna's demise,

From Wiki:
"The criminal charges focused on the car's steering column, which was found to have sheared off at a point where a modification had been made. The prosecution alleged that the column had failed causing the accident and the Williams team conceded to this failure, but only as caused by the crash impact. Senna had not liked the position of the steering wheel relative to his seating position and had asked for it to be changed. Patrick Head and Adrian Newey satisfied Senna's request by having the FW16's existing shaft cut and extended with a smaller-diameter piece of tubing that was welded together with reinforcing plates. The modification was carried out in this manner as there was insufficient time to instead manufacture a longer steering shaft in time for the race."
