Yeung spoke about using classic Chinese joinery for making furniture and showed his book, Classic Joints With Power Tools, plus a book on Chinese Domestic Furniture(see links below)
He discussed the shape and use of many different joints, including tongue and groove, dovetail, mortise and tenon, as well as more complicated joints such as mitered mortise and tenon and three way miter joints.
A lap joint combined with mortise and tenon increases the strength of the joint
.
For through tenons, he advised to always cut the mortise from the outside of the board so any tearout will be on the inside and likely hidden.
Yeung then talked through the range of joints he used to make a chair while assembling that chair as we watched.
Assembling the frame of the chair
Assembling the chair seat
Adding small panels in the arms for strength
He demonstrated frame and panel construction with a center support that he used for the seat. Assembly of the seat started with joining boards together into a panel using tongue and groove as well as sliding dovetails.
Yeung showed the curved scarf joints he used to lengthen the continuous curved arm rest. All of these joints are designed as interlocking, non-glued joints held together with bamboo pins. Many of the joints he demonstrated were originally used centuries ago for building construction and then migrated to furniture.
During the presentation Yeung covered how these intricate joints can be cut accurately with a tablesaw, flat top blade and carefully built jigs.
Assembling a 3 corner interlocking miter joint

Yeung also showed two tall stands

Frank talked about two very large wardrobes he recently built
and the how the client and a Task Rabbit were able to carry them up several flights,
including a corner, of stairs in his client's home.
He was impressed by they use a pair of Forearm Forklift Moving Straps to lift them.
