The Kawai has two wedges at the end of the tenon. These wedges can be
driven deeper into the tenon to tighten the joint. Once these wedges
are driven they will not get loose again for several years.
The Yamaha has a single wedge which also can be driven further to
tighten the joint. If the wedges are bottomed out then you will need to
use the CA.
The tape idea from Roger is excellent. I like to spray accelerator
around the juncture which also helps prevent drip out.
