Young Chang lyre supports buzzing

Not with Yamaha oval tenons with double wedges. A nightmare to take apart
and a bigger one to try to glue the polyester surfaces.

It is better to use electrical tape to seal around the posts and top 
block or box
and fill with thin epoxy. I have even counter sunk a long hex head sheet metal
screw alongside the tenon to lock it all together afterwards. Another method
on the top block is to install the screws from the rear completely 
through the tenon.
