How to Make a Drawbored Mortise and Tenon Jointcomments (14) March 29th, 2011 in blogs
A great thing about woodworking is that there's always something new to learn. On a recent hayrake table project, I decided to use draw-bore pegs for the first time. They helped solve a tricky glue up where clamping proved to be difficult. They came to the rescue again on a small sewing table I just built for my wife.
I've known about draw-bore pegs for quite a while, but it's one of those techniques that seemed antiquated or fussy and difficult to get right. Whatever the reason, I never got around to giving it a try. But now that I have, I realize what a great weapon it is to have in my glue-up arsenal. Basically it's an offset hole in a mortise and tenon joint. When you drive in a peg, it pulls the joint tightly together. No clamps necessary. It really works and it's really easy to do.
The trick is to drill the holes in 2 steps:
|Step one:||Start by drilling a hole through the mortised piece. Dry-assemble the pieces and mark the center point of the hole on the tenon with a drill bit.|
|Step two:||Pull the pieces apart and drill a hole in the tenon offset 1/32 toward the shoulder. I think it was the 1/32 offset that always scared me. It sounded techy, like something I needed to get exactly right in order for the joint to work. In reality, it's as easy as taking an awl and eyeballing a center point just toward the shoulder from the drill-bit mark.|
To make the pegs, I pounded some square stock through a dowel plate and tapered the end in a pencil sharpener.
You can watch me execute this technique in an excerpt from my Video Workshop series on building an Arts & Crafts-Style Hayrake Table:
