Townshend Excalibur I tonearm-cueing lever loose

A query for Townshend Excalibur I tonearm users:

Have you ever had your cueing lever come loose & fall out of the rotating cam?

Apart from sending it off for repair, has anyone successfully glued it back in?

If so, what glue did you use?

Suggestions also welcome.

For info, both the lever and the cam seem to be anodised/coated aluminium, and it looks like it was assembled by just pressing the lever into the cam.
