BMW racing outfit titanium linkages
I’ve just finished what is probably the hardest job i’ve done. The tube is 18 1/2″ long and drilled 7.7mm all the way through, the waisted rod is 12 1/8″ long, 10mm diameter waisted to 5mm. Both of them were beyond the extreme of my machines, but with perseverance, lots of tea and sheer doggedness i got them something like.
The short rods will be welded into the ends of the tube to take rose joints.
