Since the legs of the lectern are angled, it was imperative to use the strongest joint possible. I decided on the drawbored mortise and tenon.
Making the pegs from white oak.
The try-square is placed next to the piece being drilled. The try-square is used as a reference, so I can line the drill bit up with the square and know that I am boring a straight hole.
The hole in the tenon is offset by just a few mm toward the shoulder. This creates a very tight, very solid joint.
The drawbore pin aligns the joint.
As the peg is tapped into place, it is deformed slightly towards the shoulder of the tenon, which tightens the joint. Although this joint is not common today, it was used regularly in the past on pieces that would see a lot of use. Drawbored mortise and tenons were also used on pieces that were exposed to the elements such as doors and windows.
