For this particular project we went with a more straightforward fit — the joints were cut clean and seated well without needing to pull them tight with a drawbore. It still came together solidly, but drawboring is definitely something we might try on a future build.
When we built a couple chairs for Preonicke day in '22, it was decided drawboring would be something to look into in the future. Last year, those chairs were taken apart and reassembled with sap to try and keep the joints from wobbling so much.
My understanding has been that drawboring isn't to make the joins seat well, but to keep them seated tight after repeated stress on the joint. Outside of a timber frame building experiencing frequent earthquakes, I'd say something like a tenoned chair would be an example of joinery most in need of securing that way. I did notice the design was tweaked to allow green and seasoned wood to be exclusively used in mortise and tenon parts respectively, so perhaps that will be enough to take care of joints loosening with use, as last time we had pieces that served as both mortise and tenon...
