Swedish-Estonian style breast drill - part 2



In Part 1, I discussed the inspiration for and the first steps towards building a unique breast drill that I found in the classic "Woodworking in Estonia". This post continues that project.

With the lower body completed I moved on to the pad, the part to which chest pressure is applied to both steady and advance the auger bit. The book shows that the chest stock is made from a piece of tree branch. The hole for the stock tenon is bored through a knot, enabling the grain to flow around the hole which should help prevent splitting.

I selected a likely looking piece of maple from my firewood pile and started after it with a variety hand adzes and hatches.

Pretending to chop the knot swell flush to the rest of the wood.

Bark removed and rough layout lines drawn on.

Starting the work with a hatchet

More work, now with cooper's adze

More adze work, getting close now.

I love the texture left by the adze. Some of this will remain.

All in all, a very successful attempt. This is after one quick coat of my preferred finish for tools, a blend of pine tar, linseed oil, and turpentine. Several more coats will be applied after all other steps are completed.




Next up, I'll be choosing and fitting an auger bit to burn into this stock and pouring some pewter. It's about to get smoky in the wood shop (usually a very bad thing).

Swedish-Estonian style breast drill - part 1


A couple of weeks ago, I finally had a chance to pick up Lost Art Press's version of "Woodworking in Estonia". Despite being an avowed acolyte of Roy Underhill, who states that this particular book is his favorite, I'd never before read Vires's masterwork. Well, that has now changed and, frankly, it is eye opening. It made clearer so many of the relationships between tools, names for tools, and how their usage has evolved. I highly recommend the book, available here.

The book, coupled with a reread of Issue Six of Mortise & Tenon Magazine, led me to undertake a new tool project. You can see the original in the upper right hand corner of my opening image, a Swedish-Estonian breast drill. Being sans lathe at the moment (a situation to be corrected soon), I opted for the simple style shown on the right.

Vires says that many, if not most, of these drills were constructed predominantly from birch and I just happened to have an appropriate piece.

The work began with laying out the rough blank then ripping and crosscutting it free.


I then planed to my layout line giving me a square blank which enabled me to accurately lay out the center of the piece on both ends.

 I then used a center bit, with the central pike in the center of blank, to lay out the end tenon which will ultimately go into the chest stock. Using a crosscut backsaw, I sawed in to rough depth on all four sides before splitting away the waste with a chisel.

 I then used my Stearns hollow auger to cut the tenon perfectly round.

Some basic shaping, a chopped mortise in the center, and a long turning bar were then made completing the lower part of the drill.



The next post will be a detail of creating the chest stock from a piece of maple firewood. After that, I'll cover the process of fitting a pewter collar and burning an auger bit into the stock.

To Jamie Bacon: friend, craftsman, and raconteur
It's very difficult for me to believe it but it will soon be five years since Jamie Bacon of the Plane Shavings blog left our mortal world. I never had the privilege of meeting Jamie in person but, if you've ever read his blog, you'll understand why we were frequent correspondents.

His blog was superb and remains so. It is well worth another read through.

To friend Jamie, wherever you are, I hope your planes are sharp and that the walnut is all air-dried.
