How to make a Drawbore Mortice and Tenon | Paul Sellers

3-Second Blueprint (English)

1. Boring the 3/8-inch mortise hole from both faces as soon as the auger bit's snail protrudes prevents exit blowout.
2. Marking through the seated mortise and shifting the tenon bore 1/16 inch toward the shoulder creates drawbore clamping force.
3. Sizing a riven peg through a mild-steel plate and tapering an offset tip pulls the joint permanently tight without splitting.
