When purchased Aldermog had a lose gear knob. Removing it revealed one screw missing and the others tightened almost to the point of falling out the other side in a vain attempt to secure the knob.
Removing it all I found that the gear lever on the Roadster is an alloy casting that has been machined to a round at the end. So the set screws can bite nicely into the alloy, but if they are not properly tightened they damage the shaft, as had happened.
I had to re-finish the end of the shaft, first repairing the deep pits gouged by the set screws with Epoxy aluminum filler and then secured the knob with new grub screws, tightened firmly with but a dab of thread lock "to be sure". Getting new grub screws was interesting, they are a metric thread but a non standard length, so I had to cut them down and file new points on the end.
