My first drawbored joint

I tried my hand at drawboring for the first time today, inspired by Peter Follansbee's hearty endorsement (skip to 10:00, and then 20:00 for the impatient).

The project in question is a toolbox made from salvaged pine. I was pleased with how the mortised sides turned out, so I didn’t want to spoil the look with fasteners. Enter the drawbore: The perfect solution to cinch up those joints and make the pesky cracks disappear.

As for the choice of peg material, split oak is commonly used given its toughness. I however opted for another resilient material: the ubiquitous bamboo chopstick! I cut the chopsticks in half, saving not the round end but the square end, so that I would have the satisfaction of driving a square peg into a round hole. I drilled 1/4” holes through the mortises, and offset the holes on the tenons by about 3/32”. With a few taps of the hammer (and a little beeswax to smooth the operation) those chopsticks sunk surely and smoothly. Pure satisfaction!

I’d like to hear your stories of drawboring, and any special techniques you may have developed.

Very nice, where did you salvage the pine from?

I found some generous sized packing crates / pallets close to where I live. They yielded full 1”x8”s, which I hand planed down to about 7/8” to keep the box from being too heavy.

Not only functional, it is very visually appealing. Good work,

Thanks doc. I’m sure a good measure of patience helps, but when shavings are flying time seems to fly right along with them!

good point,

If I think about the size of a task it is often daunting. Then I figure it will still be daunting if I don’t do anything? then I jump in, and if I don’t screw it up, about a few hours later I’m done. LOL!

Like your modelling and prototype approach. formal trainning?

You know what they say, time flies like an arrow but fruit flies like a banana.

I haven’t taken classes, but I have watched my share of Woodwright’s shop, Woodworks and other tutorial videos. Having CAD experience helps too. So many design challenges can be worked out ahead of time in 3d CAD. I know what you mean about making mistakes, they can really throw you for a loop until you invent a solution.

Have your say...
