Breadboard Ends - How do you elongate your holes?

Hey Rob,
I don’t know why you are elongating the holes. What I do is taper the end of my dowell before pounding it through.
Here's a page on drawboring.

If I understand you correctly, you’re having trouble drawboring your breadboard ends. You drill the hole with the right offset, but then when you try to elongate them you end up wallering them out so that the offset is lost. What I’d do is mark the exact, centered location for the hole. Then I’d mill a piece of material that’s a 32nd thinner than the distance from the shoulder of the tenon and use it to strike a line parallel to your shoulder. At that point I’d use a drill press and a forstner bit to drill two slightly overlapping holes on either side of your original mark, but centered on your struck line. (Unless your stock is really dry or really wet, in which case you’d shift them appropriately for the potential change in moisture content.)

Good luck.

I only made one project that called for a draw bore and it came out ok using the procedure bentlyj posted only I clamped the bread board before I marked the hole in the tenon it makes a difference of about a 64th then when you pull it out mark your drill hole 3/32 away from the joint and it should pull in nice and tight.

You just tilt the drill bit back and forth a little and test fit while drilling the tenon part of the bread board end.

I agree with JIm.

I drill two overlapping holes, remembering the most important edge of the hole. The edge of the hole closest to the end of the top is key, because it keeps the breadboard against the main section’s tenon shoulder. The breadboard can’t move in the other direction, as the shoulder won’t let it. A chisel will connect the holes.
