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. Newton nhunt@jagat.com
